TELECOMMUNICATION

 

Telecommunication is the process of sending and receiving information over long distances with the help of electronic devices.

The word telecommunication comes from the Greek word tele, meaning far off, and the Latin word communicare, meaning to share. Therefore, telecommunication means sharing information from far away.

Telecommunication helps people exchange voice, text, pictures, videos, and data quickly and easily, even when they are far apart.

Common telecommunication devices include telephones, mobile phones, radios, televisions, and computers.

Examples of telecommunication include making phone calls, sending text messages, using the Internet, attending online meetings, and watching television programs.

Network in Telecommunication

In telecommunication, a network is a system in which two or more electronic devices are connected to share information and communicate with each other.

A network mainly works in two ways:

1. Wired Network:
A wired network uses physical cables or telephone lines to connect devices.

2. Wireless Network:
A wireless network connects devices without physical wires using technologies such as Wi-Fi and mobile networks.

Through these networks, people can easily share messages, sound, pictures, videos, and data over long distances quickly and efficiently.
