Different types of media
What Are The Different Types Of Media Of Computer Network Communications?
Data can be communicated from one terminal to the central computer to other terminals through different media. These media are known as data communication channels there are cable, microwave, satellite and fiber optics.
Cable is the most popular and widely used medium to transmit data from one location to another. It includes telephone line, coaxial cable, twisted pair cable etc. Telephone lines are less expensive and easy method of transmitting data. Cable channels have very slow data transmitting rate. Microwaves channel are used for transmitting analog signals. But data is transmitted in analog through air via boosters rather than cables. This type of transmission is same as the television and radio transmission. Data is transmitted from one location to another.
Through satellites data is also transmitted in space in the form of analog signals with very high transmission rate. Special satellites are sent into space. They are normally 20,000 to 25,000 miles above the earth. With the help of satellite, data can be transmitted to any country of the world. Optic fibers are used for digital signals. In an optical fiber, semi conductors laser transmit information in the form of light with very high speed.
