What Is A Modem?

A modem is an electrical piece of apparatus, used in conjunction with a computer, designed to decode signals from analogue to digital.
It allows a network of computers, via the internet, to communicate by changing digital computerised data, to be changed in analogue data which is then sent through the telephone lines(analogue signal), and the receiving computer's modem changes it back into readable and usable digital data again.
It links homes and business with the internet and even though it is a small device it is essential is today's modern life.
Modems can be purchased depending on their speed of ability to convert the information it is given.

Modem is an electronic tool that changes computer’s digital signals into particular frequencies to go on telephone or cable lines. At the target, the receiving modem changes the frequencies back to digital signals. Modems are basically use for computers to communicate with one another over a network.
