Introduction of ICT |Information and Communication Technology|

Introduction

Today, from the time awaken in the morning to the time before we sleep, we are surrounded by media, such as newspapers, radio, television and computers. Sometimes we are not even aware about them. All these media come under the overall umbrella of what are known as today’s ICTs. Knowing and using ICTs is important in today’s fast changing knowledge society, but we very often are confused about what these media are.

Introduction of ICT  |Information and Communication Technology|

Information and Communication Technologies (ICTs) are often associated with the most sophisticated and expensive computer-based technologies. But ICTs also encompass the more conventional technologies such as radio, television and telephone technology. While definitions of ICTs are varied , it might be useful to accept the definition provided by United Nations Development Programme (UNDP): 

ICTs are basically information-handling tools a varied set of goods, applications and services that are used to produce, store, process, distribute and exchange information. 

They include the old ICTs of radio, television and telephone and the new ICTs of computer, satellite and wireless technology and the Internet. These different tools are now able to work together, and combine to form our networked world a massive infrastructure of interconnected telephone services , standardized computing hardware , the internet , radio and television , which reches into every corner of the globe. When we talk of ICTs, we refer not only to the latest computer and Internet based technologies, but also to simple audio visual aids such as the transparency and slides, , tape and cassette recorders and radio, videocassettes and television and film.

Definitions of ICT - Information and communication Technology

These older and more familiar technologies are referred to under the collective heading of analogue media while the newer computer and Internet based technologies are called the digital media.Basically ICT is the technology required for information processing , in particular, the use of electronic computers, communication devices and software applications to convert, store, protect , process , transmit and retrieve information from anywhere, anytime.

1-INFORMATION

Information refers to the knowledge obtained from reading, investigation, study or research, The tools to transmit information are the telephone, television and radio. Information is knowledge and helps us to fulfill our daily tasks.

 2-COMMUNICATION

Communication is an act of transmitting messages. It is a process whereby information is exchanged between individuals using symbols ,signs or verbal interactions. Communication is important in order to gain knowledge.


3-TECHNOLOGY

Technology is the use of scientific knowledge, experience and resources to create  processes, products that fulfill human needs. Technology is vital in communication.  The acronym ICT (Information and Communication Technology) includes all technical means that are used  for handling information and facilitating communication, including computers, network hardware, communication lines and all the necessary software . In other words, ICT is comprised of information technology, telephony , electronic media, and all types of process and transfer of audio and video signals, and  all control and managing functions based on network technologies.
