In other words, ICT consists of IT as well as telecommunication, broadcast media, all types of audio and video processing and transmission and network based control and monitoring functions.
The expression was first used in in a report by Dennis Stevenson to the UK government and promoted by the new National Curriculum documents for the UK in There are large economic incentives huge cost savings due to elimination of the telephone network to merge the audio-visual, building management and telephone network with the computer network system using a single unified system of cabling, signal distribution and management.
This in turn has spurred the growth of organizations with the term ICT in their names to indicate their specialization in the process of merging the different network systems.
They have brought about changes in other areas, particularly in knowledge management and human resources development. Increasing capacity of ICT has further been empowered by the growth of a global network of computer networks known as the Internet.
It has impacted the way business is conducted, facilitated learning and knowledge sharing, generated global information flows, empowered citizens and communities in ways that have redefined governance, and have created significant wealth and economic growth resulting in a global information society. Stands for "Information and Communication Technologies. It is similar to Information Technology IT , but focuses primarily on communication technologies.
This includes the Internet, wireless networks, cell phones, and other communication mediums. In the past few decades, information and communication technologies have provided society with a vast array of new communication capabilities. For example, people can communicate in real-time with others in different countries using technologies such as instant messaging, voice over IP VoIP , and video-conferencing.
Modern information and communication technologies have created a "global village," in which people can communicate with others across the world as if they were living next door. For this reason, ICT is often studied in the context of how modern communication technologies affect society. Many countries around the world have established organizations for the promotion of ICTs, because it is feared that unless less technologically advanced areas have a chance to catch up, the increasing technological advances in developed nations will only serve to exacerbate the already-existing economic gap between technological "have" and "have not" areas.
The definition of ICT needs a serious consideration of the general confusion in the understanding of the word 'Technology' - for without a clear understanding of 'Technology' much of the rest of this site cannot hang together.
G B Harrison Ex Trent Polytechnic gives us this definition: Technology is the process of using scientific, material and human resources in order to meet human need or purpose.
The definition of ICT therefore became: the use of information in order to meet human need or purpose including reference to the use of contemporary devices such as the Internet. However, in an ever-changing world of Video-phones, mobile computing, blogs, Skype and OSS perhaps we should no longer just include the Internet, but leave the definition at 'contemporary devices?
For example, personal computers, digital television, email, robots. Importantly, it is also concerned with the way these different uses can work with each other. In business, ICT is often categorised into two broad types of product: - 1 The traditional computer-based technologies things you can typically do on a personal computer or using computers at home or at work ; and 2 The more recent, and fast-growing range of digital communication technologies which allow people and organisations to communicate and share information digitally Let's take a brief look at these two categories to demonstrate the kinds of products and ideas that are covered by ICT: Traditional Computer Based Technologies These types of ICT include: Application Use Standard Office Applications - Main Examples Word processing E.
Microsoft Word: Write letters, reports etc Spreadsheets E. Microsoft Excel; Analyse financial information; calculations; create forecasting models etc Database E. Microsoft PowerPoint; make presentations, either directly using a software computer screen or data projector.
Publish in digital format via email or over the Internet Desktop E. Adobe Indesign, Quark Express, Microsoft Publisher; produce publishing newsletters, magazines and other complex documents. Graphics E. Accounting E. Specialised CAD programs exist for many types of design: architectural, engineering, electronics, roadways Customer Software that allows businesses to better understand their customers by Relations collecting and analysing data on them such as their product Management preferences, buying habits etc.
Often linked to software applications CRM that run call centres and loyalty cards for example. This is often achieved via networks of sending and receiving equipment, wires and satellite links.
The technologies involved in communication tend to be complex. You certainly don't need to understand them for your ICT course. However, there are aspects of digital communications that you needs to be aware of. These relate primarily to the types of network and the ways of connecting to the Internet. Let's look at these two briefly further revision notes provide much more detail to support your study.
Internal networks Usually referred to as a local area network LAN , this involves linking a number of hardware items input and output devices plus computer processing together within an office or building.
The aim of a LAN is to be able to share hardware facilities such as printers or scanners, software applications and data. It offers many more capabilities than analog phones. And it can do it all for less than half the cost.
Cloud phone service providers include powerful features not found with standard phone service. Auto attendants, call recording, custom caller ID, voicemail to email, and so much more. Plus, you can take calls and work from anywhere. We've expanded this guide to take a closer look at what you need to know about Voice over Internet Protocol. We'll cover everything you need to know, including the benefits of VoIP phone service.
VoIP is an acronym for Voice over Internet Protocol that describes the method to place and receive phone calls over the internet. Most people consider VoIP the alternative to the local telephone company.

IP telephony is a massive innovation from the century-old telecommunications system. For phone calls, the conversation is exchanged using small data packets. The internet can send these data packets around the world in less than a second. For internet telephony, these packets travel between your phone and a VoIP provider. A VoIP phone system facilitates calls between other phones or over to another telephone company. It also provides other useful functions like voicemail, call forwarding, call recording, and more.
Voice over Internet Protocol bypasses the telephone company entirely. Wherever you have a broadband internet connection, you can use VoIP. You used to need expensive, proprietary equipment to use VoIP — but that was over 20 years ago! SIP provides complete interoperability between different desk phones, conference phones, and VoIP apps. Cloud-based PBXs are responsible for features like voicemail, conferencing, and call routing.
When you think about it, they act as their own full-service phone companies that you control. Here's an honest look at the benefits and drawbacks of voice over IP. Check out our comprehensive comparison between VoIP and landlines. It'll help you understand the differences.
