In recent years the ASP model has evolved in to the software-as-a-service model, which is described later. &lt;b&gt;Authenticity&lt;/b&gt; is a way of conclusively verifying and demonstrating records, evidence and other information are in fact true and what they purport to be. &lt;br&gt;&lt;b&gt;Bar codes&lt;/b&gt; are a well-established method for fast data entry. In essence they are a series of varying vertical lines (called bars) and spaces. Bar codes typically only have ID data in them. A bar code scanner linked to a computer reads this ID. The computer then looks up all the pertinent information associated with the ID data. The correct use of bar codes can decrease employee data entry time, increase data entry accuracy and enhance an organisation&amp;#39;s operational efficiency. &lt;br&gt;&lt;b&gt;Benchmarking &lt;/b&gt;is a comparison of the cost of service delivery in one business with the costs incurred by other organisations in performing similar tasks. &lt;br&gt;&lt;b&gt;Bio-metrics&lt;/b&gt; refers to technologies for measuring and analysing human body characteristics. The market has been categorised into seven technologies: face scan, signature verification, iris scan, finger scan, voice authentication, hand/finger geometry and keystroke dynamics. Bio-metrics is seen as a way of enhancing security by uniquely distinguishing a person and to replace the need for passwords, PIN numbers or security keys. The technology is starting to be incorporated in to items requiring high security such as passports and smart cards. &lt;b&gt;Bio-technology&lt;/b&gt; is an offshoot of information technology and entails the application of technology to biology. Bio-metrics is one example of this. Other areas include gene cell research and bioagriculture such as genetically modified foods and cloned animals. &lt;b&gt;&lt;br&gt;BlackBerry &lt;/b&gt;is a wireless hand-held device from Research in Motion (RIM). It supports &amp;lsquo;push&amp;rsquo; e-mail, (an always on capability in which new e-mail is instantly and actively transferred or pushed to the Blackberry without the recipient having to formally request its transfer), a mobile telephone, text messaging, web browsing and other wireless information services. It is made available through partnerships between RIM and telecommunications vendors in a number of countries. &lt;br&gt;&lt;b&gt;Blogs &lt;/b&gt;(We&lt;u&gt;b&lt;/u&gt; &lt;u&gt;logs&lt;/u&gt;) are online journal entries of thoughts and web links that anyone can create and post. Usually they are built around a common subject matter. These can have variations such as &lt;b&gt;video blogging or vlogs&lt;/b&gt;, which consist of video diaries, as well as ones consisting only of photographs. &lt;br&gt;&lt;b&gt;Browser based business systems&lt;/b&gt; utilise a web browser as the front-end interface screen to a computer program. &lt;br&gt;&lt;b&gt;Browsers&lt;/b&gt; are a software application used to locate and display web pages. Most modern browsers can display multi-media formats such as graphics, sound and video as well as text. Browser based business systems facilitate remote access to central computer systems and provide a much more versatile and user-friendly interface to these systems. &lt;br&gt;&lt;b&gt;Business Continuity Planning &lt;/b&gt;determines how a company will keep functioning until its normal facilities are restored after a disruptive event. This encompasses how employees will be contacted, where they will go and how they will keep doing their jobs. &lt;br&gt;&lt;b&gt;Business Intelligence&lt;/b&gt; &lt;b&gt;(BI)&lt;/b&gt; is a broad category of applications and technologies for gathering, storing, analysing and providing access to data to help enterprise users make better business decisions. &lt;br&gt;&lt;b&gt;Business Process Management&lt;/b&gt; &lt;b&gt;(BPM)&lt;/b&gt; is an approach that focuses on optimising processes to help make a business more effective and efficient. BPM differs from the traditional approach to IT because it focuses on the business processes around which the organisation operates rather than the information or data needs of a department or operating unit.&lt;br&gt;&lt;b&gt;Chargeback&lt;/b&gt; entails the IT department charging user departments on whose behalf IT costs are incurred. The goal of a Chargeback system is to regulate demand for IS services by linking the user departments consumption of IT to a financial charge. &lt;br&gt;&lt;b&gt;Cloud computing &lt;/b&gt;describes the provision of IT functionality as a service over the Internet. The equipment itself, (e.g. hardware, software, communications equipment and storage) would be owned by an external service provider who would allow clients to access these resources for a fee on an &amp;#39;as needed&amp;#39; basis. Concepts such as Software as a Service are components within a Cloud computing architecture. &lt;br&gt;The advantage of Cloud Computing is that it would save an organisation from the challenges of managing and maintaining their own IT infrastructure. However, the concept is still relatively embryonic and as businesses are increasingly dependant on their information assets the jury is still out as to whether the Cloud Computing approach may impair organisations from effectively exploiting the information contained within their computer systems.  &lt;br&gt;&lt;b&gt;Computer Aided Software Engineering (CASE)&lt;/b&gt; is a category of software that provides a development environment for programming teams. CASE systems offer tools to automate, manage and simplify the software programming development process. &lt;br&gt;&lt;b&gt;Corporate Performance Management (CPM) &lt;/b&gt;is defined as the area of business intelligence that deals with monitoring and managing an organisation&amp;#39;s performance, according to key performance indicators (KPIs) such as revenue, return on investment (ROI), overhead and operational costs. &lt;br&gt;&lt;b&gt;Customer relationship Management (CRM) &lt;/b&gt;applications automate the customer-facing business processes within an organisation. Collectively, these applications serve to manage the entire life cycle of a customer, including the conversion of a prospect to a customer, and help an organisation build and maintain successful relationships with its clients. &lt;br&gt;&lt;b&gt;Data mining&lt;/b&gt; differs from traditional business intelligence query environments. In the BI scenario the user knows that certain information exists and asks it to be displayed in a certain way. In the data mining scenario the user does not know relationships exist, or even if there are any relationships at all, between different pieces of data. As such, they cannot ask a question. Instead they start with one piece of data and compare it to others to assess what relationships emerge. &lt;br&gt;&lt;b&gt;Data warehousing&lt;/b&gt; is the physical separation of an organisations operational data into a separate system where it can be interrogated without impacting the performance of the core transactional systems that run the business. &lt;br&gt;&lt;b&gt;Digital signatures &lt;/b&gt;are a specific type of electronic signature that use special software to create a unique digital fingerprint of a document (called a &amp;ldquo;hash&amp;rdquo;) that can subsequently be used to verify who the original signer was and that the contents of a document have not been changed. &lt;br&gt;&lt;b&gt;Disaster recovery planning&lt;/b&gt; falls under the umbrella of business continuity services. Disaster recovery typically focuses on the critical IT infrastructure and the need for the restoration of that infrastructure after a major disaster. A disaster recovery plan is typically a comprehensive statement of consistent actions to be taken before, during and after a disaster. &lt;br&gt;&lt;b&gt;Document Management &lt;/b&gt;is the computerised management of electronic as well as paper documents. Document management systems, typically, include an optical scanner (to convert paper documents into an electronic form), a database (to organise stored documents), and a search mechanism (to quickly find specific documents). With the growing importance attached to effective governance procedures in business document management systems are becoming increasingly important in many organisations. &lt;br&gt;&lt;b&gt;EFTPOS (online payment or epayment)&lt;/b&gt; is the capture of payment information, for example direct bank debit or credit card information, online at the merchants site. &lt;br&gt;&lt;b&gt;eLearning &lt;/b&gt;or &lt;b&gt;Online training &lt;/b&gt;entails using the Internet to deliver training to replace more traditional training methods such as classrooms and self paced studies. &lt;br&gt;&lt;b&gt;Electronic Data Interchange (EDI)&lt;/b&gt; is the transfer of data between different companies using networks such as the Internet. EDI is a mechanism for companies to electronically buy, sell and trade information via an approved set of standard interface protocols. &lt;br&gt;&lt;b&gt;Enterprise Resource Planning (ERP)&lt;/b&gt; software emerged in the 1990s as an application to address the fractured nature of the corporate data resource. Information was typically held in disparate systems from which it was difficult and laborious to provide a consolidated view of the enterprise. ERP sought to integrate all these systems into one comprehensive set of business systems which could quickly provide the executive with better insights into operating costs and profits. &lt;br&gt;&lt;b&gt;Encryption Software&lt;/b&gt; scrambles plain text and other digital information in such a way that it can only be unscrambled and read by a person with the ability to decrypt. This helps protect the confidentiality of data, applications, and users&amp;#39; identities. &lt;br&gt;&lt;b&gt;Enterprise&lt;/b&gt;&lt;b&gt; Systems Management software (ESM)&lt;/b&gt; are programs that comprise a comprehensive suite of tools to assist organizations manage all facets of their IS operations. ESM helps automate many routine and laborious systems management tasks such as software distribution, change management and backup, &lt;br&gt;&lt;b&gt;Extensible Markup Language (XML)&lt;/b&gt; is a standard that defines rules for representing data in Web documents. An XML document packages the data so it can be accessed by anything from an Excel spreadsheet to an enterprise order processing application. &lt;br&gt;&lt;b&gt;Extranets&lt;/b&gt; are defined as a network that links business partners to one another over the Internet by tying together their corporate intranets. The links enable key trading partners, (eg customers, dealers, distributors, suppliers or contractors), to exchange correspondence such as invoices, purchase orders and working documents and designs. They are a significant indicator of the rise of business to business ecommerce (B2B). &lt;br&gt;&lt;b&gt;Fault tolerant/high availability systems&lt;/b&gt; are able to respond gracefully to an unexpected hardware or software failure. There are many levels of fault tolerance, the lowest being the ability to continue operations in the event of a power failure. Many fault tolerant systems mirror all operations &amp;ndash; that is every operation is performed on two or more duplicate systems, so if one fails the other can take over. &lt;br&gt;&lt;b&gt;Firewalls&lt;/b&gt; are applications that enforce security restrictions and restrict inappropriate access to internal networks. They work by analysing each network access request against a list or database of approved source IP addresses.&lt;b&gt;&lt;br&gt;&lt;/b&gt;&lt;b&gt;Governance&lt;/b&gt; is the process by which information technology is managed in an organisation. The discipline of information technology governance derives from the increasing business focus on improving overall corporate management. The primary goal for information technology governance is to assure that investments in IT generate business value and to mitigate the risks often associated with IT projects. &lt;br&gt;&lt;b&gt;Geographical Information Systems (GIS)&lt;/b&gt; are applications for capturing, storing, checking, integrating, manipulating, analysing and displaying data related to positions on the Earth&amp;#39;s surface. Typically, a GIS is used for handling maps of one kind or another&lt;b&gt;. &lt;/b&gt;These might be represented as several different layers where each layer holds data about a particular kind of feature. Each feature is linked to a position on the graphical image of a map. &lt;br&gt;&lt;b&gt;Help Desk Management systems&lt;/b&gt; are applications that automate and formalise the process of supporting either internal end users or external customers. &lt;br&gt;&lt;b&gt;I-Mode&lt;/b&gt; is a service provided by the DoCoMo company in Japan that now offers subscribers continuous access to the Internet via the mobile telephone. The service lets users send and receive email, exchange photographs, do online shopping and banking and navigate more than 7,000 specially formatted Web sites. &lt;br&gt;&lt;b&gt;Information Lifecycle Management&lt;/b&gt; &lt;b&gt;(ILM)&lt;/b&gt; is comprised of the policies, processes, practices, and tools used to align the business value of information with the most appropriate and cost effective IT infrastructure from the time information is conceived through to its final disposition. Information is aligned with business processes through management policies and service levels associated with applications, metadata, information, and data. &lt;br&gt;&lt;b&gt;Intranets&lt;/b&gt; are a self-contained, internal network linking multiple users by means of Internet technology, enabling users with Web browsers and Internet clients to access information and applications hosted on servers. &lt;br&gt;&lt;b&gt;IT Architecture&lt;/b&gt; is the overall structure of, and interrelationships among, the data, business logic, and interfaces of a company&amp;rsquo;s computers and other hardware, applications, databases, operating systems and networks.. &lt;br&gt;The &lt;b&gt;IT Infrastructure Library (ITIL&lt;/b&gt;(&amp;reg;)&lt;b&gt;) &lt;/b&gt;is a series of documents that are used to aid the implementation of a framework for IT service management (ITSM). This framework defines how service management is applied within specific organisations. Although originally developed by the UK government it is now rapidly being adopted across the world as the standard for best practice in the provision of IT service. &lt;br&gt;&lt;b&gt;Internet Relay Chat (IRC)&lt;/b&gt; is the Internet&amp;#39;s equivalent of two-way radio. It lets people participate in real-time conversations. Using an IRC client (program) you can exchange messages interactively with other people all over the world. When logged into a chat session the user &amp;quot;converses&amp;quot; by typing messages that are instantly sent to other chat participants. &lt;br&gt;&lt;b&gt;Knowledge management&lt;/b&gt; is a formal process that evaluates a company&amp;#39;s people, organisational processes and technology and develops a solution to get the right information to the right people at the right time to improve productivity. Knowledge management software can be classified into knowledge management infrastructure (i.e. capturing information) and knowledge management access (i.e. harnessing the data captured). &lt;br&gt;&lt;b&gt;Legacy systems&lt;/b&gt; are any information system, including software and hardware, which may no longer be fully supported by its manufacturer or the user or have been in use for a long time. &lt;br&gt;&lt;b&gt;Linux &lt;/b&gt;is a Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public Licence the source code for Linux is literally freely available to everyone. &lt;br&gt;&lt;b&gt;Managed Services &lt;/b&gt;are a form of selective outsourcing in which an organisation selects a service provider to assume responsibility for delivering a specific technical function or capability. These services are typically sold on an annual subscription basis with a usage-based fee structure. The potential advantage of managed services is that it enables companies to better utilise internal staff; it could reduce maintenance costs and it might bring a commercial focus to the delivery of an IT service. &lt;br&gt;&lt;b&gt;Marketplaces or online exchanges&lt;/b&gt; add another option to the supply chain. To all intents and purposes these are electronic equivalents of the traditional shopping mall. Whereas shopping centre managers charge retailers rent to set up shop, eBusiness exchanges which host the online trading environment enlist participants for a similar fee. The idea is that competition between participants drives down prices but that the volume of business compensates for the trading discounts. &lt;br&gt;A &lt;b&gt;Mashup &lt;/b&gt;is a website or web application that seamlessly combines content from more than one source into an integrated experience. Content used in mashups is typically sourced from a third party via a public interface or API. Other methods of sourcing content for mashups include Web feeds (e.g. RSS) and JavaScript. &lt;br&gt;&lt;b&gt;Metadata &lt;/b&gt;is data that describes other data. For example, the index or table of contents in a book could be considered a form of metadata. &lt;br&gt;&lt;b&gt;Middleware &lt;/b&gt;is defined as a set of common services that enable applications and end users to exchange information across networks. &lt;br&gt;&lt;b&gt;Multi-function peripherals (MFP) or Multi-function devices (MFD) &lt;/b&gt;are single devices that can perform multiple functions such as printer, photocopier, fax machine and scanner. &lt;br&gt;&lt;b&gt;Object orientated programming (O/O)&lt;/b&gt; is a type of programming in which programmers define not only the data type of a data structure but also the types of operations (functions) that can be applied to the data structure. The principal advantage of object-orientated programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. This makes object-orientated programs easier to modify. &lt;b&gt;Offshoring &lt;/b&gt;describes an increasing global business practice for companies to relocate various parts of their operations to locations outside the country where the service is being delivered. It can be viewed as outsourcing to foreign countries. &lt;br&gt;&lt;b&gt;Outsourcing&lt;/b&gt; involves paying another company to provide services for which a company might otherwise have employed its own staff to perform. The decision to outsource various functions is a business model decision, whereby an organisation determines how and where internal resources will be utilised and how external resources can be applied to deliver value and ultimately drive operational efficiency and focus. &lt;br&gt;&lt;b&gt;PDA (Personal Digital Assistant)&lt;/b&gt; is a broad category of handheld hardware devices commonly used in place of an appointment and address book. As PDAs increase in power and speed, their functionality is also growing to include audio/video and wireless e-mail capabilities. A growing number of PDAs are being integrated with mobile phones to provide a single mobile handheld solution. &lt;b&gt;Phishing and pharming &lt;/b&gt;are ways that hackers seek to get computer users to disclose sensitive security data such as access details to Internet banking sites. With &lt;b&gt;phishing &lt;/b&gt;people are sent emails claiming to be from their bank asking them to &amp;ldquo;confirm&amp;rdquo; their account details and passwords. More recently this practice has evolved to &lt;b&gt;pharming&lt;/b&gt;. In this case hackers have devised a virus-laden email that invades computers and secretly redirects users&amp;rsquo; computers from financial sites to a scammers fake site that look almost exactly the same as the real one. As such, when people type in their account details and passwords they are unaware they have been hijacked to a scammer&amp;rsquo;s &amp;ldquo;pharm&amp;rdquo; site. &lt;br&gt;&lt;b&gt;Performance Management Systems &lt;/b&gt;is the latest term&lt;b&gt; &lt;/b&gt;for what was once called Executive Information Systems (EIS) and Business Intelligence (BI). It takes the concept further by highlighting that the role of these systems is to assist the organisation achieve desirable business outcomes. &lt;b&gt;&lt;br&gt;PKI&lt;/b&gt; &lt;b&gt;or Public Key Infrastructure &lt;/b&gt;is a system of people, processes and technology for issuing and managing digital certificates that can be used for online identification, digital signing, encryption and other information security related functions. &lt;br&gt;&lt;b&gt;Quality certification&lt;/b&gt; is a process that identifies that an organisation has achieved a level of service delivery commensurate with an internationally agreed standard. &lt;br&gt;&lt;b&gt;Radio frequency ID (RFID&lt;/b&gt;) tags are coils that allow for the reading and writing of information remotely by specialist devices. They have potential for a number of applications in the supply chain and in retail, principally in replacing barcodes. &lt;b&gt;Rapid Application Development (RAD) &lt;/b&gt;is a programming system that enables programmers to quickly build working programs. &lt;br&gt;&lt;b&gt;Routers&lt;/b&gt; are hardware devices and/or software applications that route packets of information travelling over the Internet and divert them to the appropriate location on the Internet, as determined by their destination IP address. &lt;br&gt;&lt;b&gt;Really Simple Syndication (RSS)&lt;/b&gt; is an XML based format which allows web publishers to create and disseminate feeds of data based on the content of their web site. RSS feeds typically contain article headlines, links and descriptions. When the website is updated the feeds are simultaneously dispatched to interested recipients. Readers can view the content of RSS feeds using specialist news readers which allow people to view feeds from multiple sources. &lt;br&gt;&lt;b&gt;Sales Force Automation&lt;/b&gt; &lt;b&gt;(SFA)&lt;/b&gt; are software applications to automate the business tasks of sales, including order processing, contact management, information sharing, inventory monitoring and control, order tracking, customer management, sales force analysis and employee performance evaluation. SFA is often used interchangeably with CRM. However, CRM does not necessarily imply automation of sales tasks. &lt;br&gt;&lt;b&gt;Service-oriented architecture&lt;/b&gt; &lt;b&gt;(SOA)&lt;/b&gt; defines how two computing entities, such as programs, interact in such a way as to enable one entity to perform a unit of work on behalf of another entity. SOA is a higher level of application development that, by focusing on business processes, and using standard interfaces, helps mask the underlying technical complexity of the IT environment. This ability assists the integration of different IT environments. In reality SOA is something of an IT version of a philosophy. As with other philosophies, such as Buddhism and economic rationalism, SOA is not something that you can purchase. It is a way of living and working. The gains come through long term commitment rather than instant gratification. However, this does require business users to take something of a &amp;lsquo;leap of faith&amp;rsquo; that the promised gains will eventually be realised. &lt;br&gt;&lt;b&gt;Single sign-on&lt;/b&gt; &lt;b&gt;(SSO)&lt;/b&gt; is a solution to the problem of too many passwords to too many IT applications. Single sign-on is an authentication process that permits a user to enter a single identity and password in order to access all systems and resources where the user has access permission. After initial authentication, the user is known throughout the network and additional requests for authentication are unnecessary. &lt;br&gt;&lt;b&gt;Smart card technology&lt;/b&gt; is an identification card or key that can combine an access key, identity card and cash or credit card functionality. &lt;br&gt;&lt;b&gt;Software-as-a-service (Saas)&lt;/b&gt; is the on-demand delivery of software as an internet service via a web browser, rather than as a product that must be purchased, installed and maintained. In a nutshell, software-as-a-service turns the acquisition of software from a licence sale to a subscription service. &lt;br&gt;&lt;b&gt;Storage area networks (SANs)&lt;/b&gt;, and their counterparts &lt;b&gt;network attached storage (NAS)&lt;/b&gt;, are dedicated networks of storage arrays in which multiple disk drives are presented to the attached servers as a single &amp;ldquo;virtual&amp;rdquo; storage entity. They consolidate disk and, thus, data resources into storage farms for cost savings and easier maintenance. &lt;br&gt;&lt;b&gt;Storage over IP (SoIP)&lt;/b&gt; technology allows for accessing storage devices over the Internet so data can be shared between users and separate computers at different locations. This functionality ensures more efficient use of storage and it provides for greater data security since files can be automatically backed up to off-site locations. &lt;br&gt;&lt;b&gt;Supply chain management&lt;/b&gt; entails the automation of the selling, procurement and delivery process. It aims to streamline the mechanics of acquiring and distributing product to provide cost savings for both suppliers and their customers. At its most advanced it entails the integration of systems between different companies so purchase orders, order processing, dispatch and invoicing occur online. &lt;br&gt;&lt;b&gt;Systems development&lt;/b&gt; is the task of building computer systems and applications by computer programmers and business analysts. &lt;br&gt;&lt;b&gt;Tablet PCs&lt;/b&gt; are a type of notebook computer that has a screen on which the user can write using a special-purpose pen or stylus. This handwriting is digitised and can be converted to standard text through a handwriting recognition program. Tablet PCs also typically have a keyboard and/or mouse for input. &lt;b&gt;Telecommuting&lt;/b&gt; is a term coined in the early 1970s to describe a geographically dispersed office where employees can work at home on a computer and transmit data and documents to a central office via telephone lines. &lt;b&gt;Hotelling &lt;/b&gt;or &lt;b&gt;Hot desking&lt;/b&gt; is often associated with telecommuting and entails desk sharing in a central office among those who either telecommute or else who spend most of their working life outside of the office (e.g. sales representatives). &lt;br&gt;&lt;b&gt;Thin client computing&lt;/b&gt; was first popularised by Citrix in the late 1990&amp;rsquo;s. It entails consolidating PC systems resources such as disks and software around a central server and using smaller PC clients integrated with these servers. This offers cost savings in resources as these disks and software can serve multiple users. It also simplifies the systems management tasks, eg software distribution or backup, at the desktop. &lt;br&gt;&lt;b&gt;Videoconferencing &lt;/b&gt;technology allows two or more people at different locations to see and hear each other at the same time. In addition, it is often possible to share computer applications such as Internet pages, library catalogues, documents, or software. This communications technology offers new possibilities for remote learning and is a mechanism to conduct some meetings without the need for participants to travel from remote locations. &lt;br&gt;&lt;b&gt;Virtualization &lt;/b&gt;refers to the pooling of IT resources in a way that masks the physical nature and boundaries of those resources from resource users. In effect it decouples software from hardware. The benefit is that it can help raise the utilization rates of servers and, so, facilitates server consolidation for cost savings and simplified maintenance. &lt;br&gt;&lt;b&gt;Viruses &lt;/b&gt;are a man made program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. A virus is dangerous because it will quickly use all available memory and bring the system to a halt. More disconcertingly it may even delete critical system files without your knowledge. &lt;br&gt;&lt;b&gt;Voice over Internet Protocol (VoiP)&lt;/b&gt; is a method of transmitting voice traffic over the Internet using Internet Protocol (IP). Many VoiP companies offer international long distance rates that are much lower than those offered by the major long distance carriers, making VoiP an attractive alternative for consumers who frequently place international calls. VoiP service is not limited to the international market; it can also be used to place domestic calls.&lt;br&gt;&lt;b&gt;Web services&lt;/b&gt; allow different Internet based applications from different sources to communicate with each other without time-consuming custom coding. These software-based functions can be found and accessed by other applications using standard common protocols. &lt;br&gt;&lt;b&gt;Wiki&lt;/b&gt; &amp;ndash; &lt;b&gt;a wiki&lt;/b&gt; is any website that allows users to easily add and edit content. The most recognised example is the Wikipedia online encyclopedia. However, a business could easily apply the wiki concept to many areas such as process mapping, project management or business continuity plans. &lt;br&gt;&lt;b&gt;Workflow&lt;/b&gt; software can automatically redirect files to alternative staff if a series of business rules are activated. Such a rule could be the fact that a file has not been accessed for a period of time. Therefore, workflow has the ability to circumnavigate blockages in an organisation and can accelerate the processing of work. &lt;br&gt;&lt;b&gt;Worms&lt;/b&gt; are a type of &amp;ldquo;human created&amp;rdquo; malicious code or computer virus that replicates itself on a computer, using up more and more of the computer&amp;rsquo;s memory and system resources until the computer becomes sluggish or even inoperable.&lt;br&gt;&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item><item><title>Communication terms and definitions</title><link>http://itdictionary.wetpaint.com/page/Communication+terms+and+definitions</link><author>morganhind</author><guid isPermaLink="false">http://itdictionary.wetpaint.com/page/Communication+terms+and+definitions</guid><pubDate>Sat, 02 Feb 2008 17:07:54 CST</pubDate><description> 			Communication and telecommunication terms tend to be a little more complex than other IT terms, if that is possible. This page seeks to demystify them.&lt;br&gt;&lt;br&gt;  &lt;b&gt;Asynchronous transfer mode (ATM) &lt;/b&gt;networks are widely used by telecommunications service providers and large companies to consolidate data traffic from multiple sources and different types of media (e.g. voice, video, and data).&lt;br&gt;&lt;b&gt;Digital subscriber line (DSL). &lt;/b&gt;DSL is a technology for bringing high-bandwidth broadband Internet access to homes and small businesses over ordinary copper telephone lines. &lt;br&gt;&lt;b&gt;Digital Subscriber Line Access Multiplexer (DSLAM)&lt;/b&gt; is a mechanism at a phone company&amp;#39;s central location that links many customers. The more DSLAMs a phone company has, the more customers it can support with connections to a single high-speed line. &lt;br&gt;&lt;b&gt;Fibre to the node (FTTN)&lt;/b&gt;, also called fibre to the neighbourhood, is a telecommunication architecture based on fibre-optic coaxial cable or twisted pair wiring. The area served by the node is usually less than 5,000 feet in radius and can contain several hundred customers. Fibre to the node allows delivery of broadband services such as high speed Internet. Unlike the competing fibre to the premises (FTTP) technology, fibre to the node can use the existing coaxial or twisted pair infrastructure to provide &amp;quot;last mile&amp;quot;service to the home or premises. For this reason, fibre to the node costs less to deploy. However, it also has lower bandwidth potential than fibre to the premises.&lt;br&gt;&lt;b&gt;Fibre to the premises&lt;/b&gt; &lt;b&gt;(FTTP)&lt;/b&gt; is a form of fibre-optic communication delivery in which optical fibre is run directly onto the clients&amp;#39; premises. This contrasts with other fibre-optic communication delivery strategies such as fibre to the node (FTTN) which depends upon more traditional methods such as copper wires or coaxial cable for &amp;quot;last mile&amp;quot; delivery.&lt;br&gt;&lt;b&gt;Frame relay. &lt;/b&gt;This is a dedicated, public data networking service offered by communications service providers for LAN-to-LAN connections. Its strength is that it can efficiently handle &amp;#39;bursty&amp;#39; communications by quickly adjusting bandwidth to meet demands.&lt;br&gt;&lt;b&gt;High Speed Downlink Packet Access (HSDPA)&lt;/b&gt; is a mobile telephony communications protocol which allows networks based on Universal Mobile Telecommunications System (UTMS) to have higher data transfer speeds and capacity &lt;br&gt;&lt;b&gt;Integrated Services Digital Network (ISDN). &lt;/b&gt;ISDN is a communications protocol offered by telephone companies that permits telephone networks to carry data, voice, and other source traffic. &lt;br&gt;&lt;b&gt;IP (Internet Protocol) &lt;/b&gt;is the communication method or protocol used to send data from one computer to another over the Internet. Each computer on the Internet has an IP address (analogous to a phone number) that allows routers to find and forward data to the appropriate computers on the Internet.&lt;br&gt;&lt;b&gt;IPsec&lt;/b&gt; &lt;b&gt;(IP security)&lt;/b&gt; is a suite of protocols for securing Internet Protocol communications by authenticating and/or encrypting each IP packet in a data stream. IPsec also includes protocols for establishing cryptographic keys.&lt;br&gt;&lt;b&gt;Local area networks (LANs) &lt;/b&gt;are computer networks than span a relatively small area. They usually connect workstations and personal computers so they can access common data files and share expensive devices such as printers, communication lines and software programs. It is possible to link one LAN to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a &lt;b&gt;wide area network&lt;/b&gt; &lt;b&gt;(WAN)&lt;/b&gt;. &lt;br&gt;&lt;b&gt;LAN switches&lt;/b&gt; are hardware devices that provide more efficient communications between devices attached to a local area network, such as computers and peripherals (e.g. printers).&lt;br&gt;&lt;b&gt;Local multipoint distribution service (LMDS).&lt;/b&gt; A high-speed fixed wireless service used to provide local telephone service without the need to lay fibre cable to individual customer sites. Some service providers employ LMDS as a way to provision local telephone service, high-speed Internet access, and video services without using the local telephone company&amp;#39;s network.&lt;br&gt;&lt;b&gt;Multiprotocol Label Switching (MPLS).&lt;/b&gt; This is an initiative to simplify and improve IP packet exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion and bottlenecks. In particular, MPLS will allow telecommunication suppliers to provide their clients with different kinds of data streams based on priority and service plan. For instance, those who subscribe to a premium service plan, or those who receive a lot of streaming media or high-bandwidth content, will see minimal latency and packet loss. &lt;br&gt;&lt;b&gt;Multichannel multipoint distribution service (MMDS).&lt;/b&gt; MMDS is a fixed wireless technology for high-speed data, video, and voice. It is a way of distributing cable TV signals through microwave from a single transmission point to multiple receiving points without laying fibre or cable to each customer. &lt;br&gt;&lt;b&gt;Network access control (NAC)&lt;/b&gt;, also known as network admission control, is a method of bolstering the security of a proprietary network by restricting the availability of network resources (e.g. files and programs) to devices that comply with a defined security policy&lt;b&gt;&lt;br&gt;P2P (Peer to peer)&lt;/b&gt; is a method for one computer to locate another computer on a network and then communicate directly with it once the connection has been made.&lt;br&gt;&lt;b&gt;Public Switched Telephone Network (PSTN)&lt;/b&gt; refers to the international telephone system based on copper wires carrying analog voice data. This is in contrast to newer telephone networks based on digital technologies, such as ISDN and FDDI. Telephone service carried by the PSTN is often called plain old telephone service (POTS). &lt;br&gt;&lt;b&gt;SMS (Short Message Service) &lt;/b&gt;is a type of text message sent and received from a mobile digital phone.&lt;br&gt;&lt;b&gt;Sniffer &lt;/b&gt;is a software application that monitors Internet network traffic by reviewing packets of information as they pass through the network.&lt;br&gt;&lt;b&gt;  Unified communications&lt;/b&gt; seeks to integrate the various forms of business communications such as voice, video, text, email and voicemail through a central communications dashboard. The goal is to ensure that whatever communication option is utilised you are able to reach a key executive wherever they are located at any point in time.  &lt;br&gt;&lt;b&gt;Voice over Internet Protocol (VoiP).&lt;/b&gt; VoiP is a method of transmitting voice traffic over the Internet using Internet Protocol (IP). Many VoiP companies offer international long distance rates that are significantly lower than those offered by the major long distance carriers, making VoiP an attractive alternative for consumers who frequently place international calls. VoiP service is not limited to the international market; it can also be used to place domestic calls. &lt;br&gt;&lt;b&gt;Virtual private network (VPN).&lt;/b&gt; A VPN exists between two computers by encrypting all information passing back and forth between them. The private network is virtual because, unlike actual private networks, there is no dedicated piece of wire running between the two computers. VPNs are commonly used by organisations to give remote employees secure access to internal networks. &lt;br&gt;&lt;b&gt;WAP or Wireless Application Protocol. &lt;/b&gt;This is an open global standard developed to convert data that is normally viewed on a large screen into a form that is readable from smaller screens, such as on pagers and cellular or mobile handsets. In other words, WAP allows wireless devices to have access to Internet and intranet-based information and services. &lt;br&gt;&lt;b&gt;WiMAX or Worldwide Interoperability for Microwave Access&lt;/b&gt; is a standards-based communications technology. The greater range and higher bandwidth of WiMAX gives telecommunication service providers (telcos) the ability to offer broadband Internet access directly to homes without having to worry about the problems that can arise when laying down a physical connection over the so-called &amp;ldquo;last mile&amp;rdquo;, which connects the home or business with the service providers&amp;rsquo; main networks.&lt;br&gt;&lt;b&gt;Wireless LANs or WiFi &lt;/b&gt;are a data communications system that provides wireless peer-to-peer (e.g. PC-to-PC, PC-to-hub, or printer-to-hub) and point-to-point (e.g. local area network(LAN)-to-LAN) connectivity within a building or campus environment.  &lt;br&gt;&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item><item><title>Home</title><link>http://itdictionary.wetpaint.com/page/Home</link><author>morganhind</author><guid isPermaLink="false">http://itdictionary.wetpaint.com/page/Home</guid><pubDate>Thu, 09 Aug 2007 00:17:04 CDT</pubDate><description>&lt;b&gt;Business definitions of IT terms and concepts&lt;/b&gt; &lt;br&gt;&lt;br&gt;It took Dr Johnson over eight years to complete the first English dictionary. It is a good job he did not start the task in the Information Age. With the plethora of new terms and buzzwords that abound in IT he may never have finished the task. However, this also means that businesses are vulnerable to misconceptions and false expectations about IT investments if there are no understandable definitions of what IT concepts actually mean. &lt;br&gt;As a researcher who places an emphasis on explaining IT issues in business language, Peter Hind has set out to attempt to address this deficiency. Below are a number of definitions or explanations of IT concepts and terms that Peter has encountered in recent years. A plain English description of the term is placed alongside it. Peter would welcome emails (&lt;a href=&quot;http://itdictionary.wetpaint.commailto:phind@launchpadmktg.com.au&quot; target=&quot;_top&quot;&gt;phind@launchpadmktg.com.au&lt;/a&gt;) from readers of terms not included in the dictionary for which they would like a plain English translation. In addition, if you wish to refine or challenge a definition please also feel free to contact me and I shall invite you to be a contributor to the site.&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item></channel></rss>
