What is Modulation Process?

modulation means the conversion of Digital signals into analog signals and sending them over telephone lines this process is called Modulation Process. For example, this is digital signal 110112 the modem converts these Digital Signals into Analog Form and sends it over telephone lines to the receiver.

What is De-Modulation Process?

De-Modulation means the conversion of Analog signals into Digitals Signals and this process is called De-Modulation Process. For example Conversion of Analog Signal into 110112.

The modem is a commonly used communication device it sends and receives data on the internet from one computer to another computer through telephone lines it is necessary to have modems for both computers that send and receive data on the internet.

How Modem Works?

The modem works as a Modulation and Demodulation Computer stores information in the form of a digital signal however the information transmitted over the telephone is an analog signal. The modem receives data in digital form and converts it into analog form this process is known as the modulation process.

the conversion of digital signals into the analog signal is known as Demodulation. it is necessary that the Modem requires telephone lines otherwise modem cannot any function and our computer cannot be connected to the internet. Modems have different speeds normals its speed is 2400bps, 9600bps, and 56.5kbps. 

Types Of Modems?

There are three types of modems in terms of size and Shape such types are
  • External Modem
  • Internal Modem
  • Wireless Modem 

External Modem:

The external modem is connected to the computer with the help of COM 1 or COM 2 Ports
The external power supply is applied to it & it is very easy to set up and portable.

Internal Modem:

The internal Modem is attached inside the system through expansion slots
it is not portable so cannot move from one pc to another & the setup of internal modem is very difficult and complicated.

Wireless Modem:

Wireless modem transfers data through the air instead of cable. They are specially designed to work in the wireless local area network they are also called Radiofrequency network
