Application Areas of ICT

ICT has different types of applications for different fields. These fields are explained below:
Teleconferencing
The word tele means distance. The word conference means discussion and consultation. It is simply defined as the process of holding a conference via telephone or network connection. Teleconferencing is the live exchange and mass circulation of information among several persons and machines remote from one another but linked by a telecommunication system

Video conferencing
With videoconferencing people can interact as if they were talking face to face with both images and sound relay in real-time. Thus far video conferencing has been used in the following fields; Business, Distance learning, Home offices, Legal environment and Telemedicine.

Telepresence
Telepresence also called virtual presence, is a technique to create a sense of physical presence at a remote location using multimedia such as sound, vision and touch.

Telecommunication and Networking
Telecommunication is the process of sending and receiving an electrical signal over a large distance by electronic means. A single telecommunications circuit consists of two stations, each equipped with a transmitter and a receiver. There are certain mediums of telecommunication systems such as coaxial cables, fibre optics, radio frequency and air etc. a telecommunication network is a network of nodes and links and the communication signal passes through one link to another.

Tele-computing
It is a generic (common) term referring to the use of computers for communication. The term includes communication using computers linked either one-to-one or in networks of interlinked computers. The most common use of interlinked computers now is by the way of the internet and Intranet. An intranet is a private network which serves a single organization, such as a corporation.

Messaging
The most common forms of messaging are emails, paging, Short Message Service (SMS), Enhanced Message Service (EMS), Multimedia Message (MMS) and Instant Messaging.

Information Search, Retrieval and archival
Information Retrieval is the science of searching for documents, information within documents, and metadata about the document, as well as that of searching relational databases and the World Wide Web. An Archival Information System consists of an organization of people and systems that has accepted the responsibility to preserve information and make it available for a designated community

ICT-Based Gadgets

A gadget is a small technological device or an appliance that has a particular function. An ICT gadget is therefore any technological tool that can be used to manipulate information.
Examples of ICT gadgets include computers, Automated teller machines (ATM), Dispensing machines, Radio sets, Television sets, Fax machines, Telephone, GSM, etc.
Mobile Phone
Cell phones, also known as mobile phones or wireless phones, are hand-held phones with built-in antennas. Unlike home phones, cell phones can be carried from place to place with minimum fuss.
Computer
A computer is a programmable machine that inputs, processes and outputs data. A computer system refers to the computer and all its equipment.
Fax Machine
Fax machine is a short form for a facsimile machine. It is a device that can send or receives text and pictures (graphics) over a radio broadcast or a telephone line.
Automated Teller Machine (ATM)
Automated Teller Machine also known as automated banking machine (ABM) or cash machine is a computerized telecommunication device that provides the client of a financial institution with access to financial transactions in public space without the need for a cashier, a human clerk or a bank teller.
Dispensing machine
A dispensing machine is a machine that gives items to customers automatically after the customer inserts currency or credit into the machine.

Radio Set
A radio receiver (commonly also called a radio) is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information
Television
Television or TV is a telecommunication medium used for transmitting sound with moving images in monochrome (black-and-white), in colour, and in two or three dimensions.
VR (Virtual Reality) Camera
VR employs tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. It can be used in entertainment, education and business.
