Type of communication technology
Based on the advancement and mode of technology, telecommunication is categorized as −
- Wireless Communication
Let us now discuss each category −
Telecommunication is a technique of transmission of information from one location to another by electromagnetic means.
Different types of information can be transferred through a telecommunication system, such as voice, text, pictures, etc.
Modern Telecommunication System
The modern form of telecommunication involves computer technology and it is capable of transferring wide range of data including audio, video, textual, many other computer files.
Major components of modern telecommunication are;
- Hardware− for example, computer system and modems.
- Software− this controls the Computer programs.
- Media− this is the communication outlet, wired or wireless.
- Networking− this technology connects various computer systems.
- Protocols– these rules govern information and communication transmission system.
Wireless communication is a technique of transmitting the information or power between two or more points which are actually not connected with the physical wire/conductor.
The most common wireless technology uses radio waves. Microwave transmission is another technology.
The world’s first wireless telephone communication took place in 1880. This was experimented by Alexander Graham Bell and Charles Summer Tainted. Both of them together invented and patented the ‘photo phone.’
Photo phone was a sort of telephone which conducted audio conversations wireless over modulated light beams i.e. electromagnetic waves.
However, in the 21st century, the invention of cellular phones radically changed the concept of communication system and made available the wireless communication system even in the remote part of the country.
