1. ICT refers to technologies that provide access to
information through telecommunications. It is similar to
Information Technology (IT), but focuses primarily on communication
technologies. Do you have the idea?
2. A computer network or data network is a telecommunications
network that allows computers to exchange data. In computer
networks, networked computing devices pass data to each other along
data connections. The connections (network links) between nodes are
established using either cable media or wireless media. The
best-known computer network is the Internet.
3. E-mail is a system that allows messages to be sent and
received by computers. E-mail is the most common form of electronic
communication.
4. Video-conferencing is a system that allows people to have
conversations and meetings with other people in different
locations, but without leaving their office.
5. Telecommunication is communication at a distance by
technological means, particularly through electrical signals or
electromagnetic waves. Due to the many different technologies
involved, the word is often used in a plural form, as
telecommunications.
6. Satellite Internet access is Internet access provided
through communications satellites. Modern satellite Internet
service is typically provided to users through geostationary
satellites that can offer high data speeds, with newer satellites
achieving downstream data speeds up to 15 Mbps.
7. The Global Positioning System (GPS) is a space- based
satellite navigation system that provides location and time
information in all weather conditions, anywhere on or near the
Earth where there is an unobstructed line of sight to four or more
GPS satellites.[1] The system provides critical capabilities to
military, civil and commercial users around the world. It is
maintained by the United States government and is freely accessible
to anyone with a GPS receiver.
8. A mobile phone (also known as a cellular phone, cell phone,
a hand phone, or even simply a phone) is a phone that can make and
receive telephone calls over a radio link while moving around a
wide geographic area. It does so by connecting to a cellular
network provided by a mobile phone operator, allowing access to the
public telephone network. By contrast, a cordless telephone is used
only within the short range of a single, private base station.
