In today’s article, we are going to give you complete information about the modem.
You must have heard the name of modem before, through this networking device you can computer or directly to the smartphone Internet Can be connected to by telephone line, cable or satellite connection. Although use the modem LAN network But modem is an important device that you should be aware of in order to connect your device to the Internet.
So we thought why not provide you complete information about the modem today. To get complete information about the modem, read this article till the end. So let’s start this article without any delay what is modem in hindi,
What is a modem (Computer Modem in Hindi)
Modem is made up of two words in which MO means Modulator and dem means Demodulator which shows its working. Modem is an abbreviation of Modulation and Demodulation.
Digital signal is converted into analog signal by modem, this process is called Modulation and similarly the process of converting analog signal into digital signal is called Demodulation. Modems perform both these functions together and for this reason, the word modem is a combination of modulate and demodulate.
Definition of Modem
A modem is a networking device that transfers data from a telephone line to a computer network through modulation and demodulation.
Modem Full Form
The full form of Modem is Modulator / Demodulator, as we have also mentioned above, Modem is made up of two words Mo and Dem.
History of Modem
Digital modems were developed during the 1950s out of a need to transmit data to the North American air defense. modem use public switched telephone Network And used for data communication on PSTN.
The first commercial modem was made in 1962 by AT&T named Bell 103. The speed of this modem was 300 bits per second. In 1996 Dr. Brent Townshend invented the 56K modem, the speed of this modem was 56Kbps. Earlier the speed of the modem was measured in baud, but due to the development of computer technology, it is measured in bits per second.
The demand for modems also increased with the popularity of the World Wide Web in the late 1990s. Initially, dial-up modems provided Internet access to many homes in the world. In a dial up modem, a number had to be dialed to connect to the Internet service provider. The data transfer rate in these modems was up to 56 Kbps.
Modern modems are usually DSL and cable modems also known as broadband
After reading the article till here, you must have understood what a modem is, now you know how a modem works.
How Modem Works (How does Modem Work in Hindi)
Modem is a device in which the process of Modulation and Demodulation takes place simultaneously. Modem is used to transfer telephone line or cable data from one computer network to another computer network. Computer networks operate in digital mode and analog mode is used in telephone lines or cables.
Modulator converts the data from digital mode to analog mode at the transmitting end and on the other hand the demodulator converts the same data from analog mode to digital mode at the receiving end.
Type of Modem
Modems can be of many types depending on their characteristics, out of which we have told you about some of the major types of modems below –
1 – Dial up Modem
Modems used on dial-up networks convert data between the analog form used on telephone lines and the digital form used on computers. An external dial-up modem plugs into the computer at one end and the telephone line at the other end.
In this type of modem, a number has to be dialed to connect to the Internet service provider. Modern dial-up network modems transmit data at a maximum speed of 56,000 bits per second.
2 – Broadband Modem
those used for DSL or cable internet access broadband Modems use advanced signal technology to achieve higher network speed than dial-up modems.
Broadband modem Often referred to as a high-speed modem, a cellular modem is a type of digital modem that establishes Internet connectivity between a mobile device and a cell phone network.
3 – Fax Modem
Fax Modem can also be used as a fax in the computer. With the help of this modem, you can receive fax from other computer and also send fax to other computer.
4 – Cable Modem
in cable modem coaxial cable are used which are attached to the back edge of the modem.
5 – Removable Modem
This modem can be inserted or removed as needed, and these modems are used in traditional laptop PCMCIA slots.
6 – Wireless Modem
Wireless modem also known as Radiofrequency Modem, this type of modem is designed to work with cellular technology and wireless LAN.
Features of Modem
Following are the main features of modem –
- Modem has both Modulation and Demodulation process.
- Modems are available in many types of transmission speed, the speed of a good modem is 9600bps, 14400bps, 28000bps or 56800bps.
- The modem allows the computer network to send and receive data over a telephone line, cable or satellite connection.
- You can connect your device to the Internet through a modem.
- The modem transmits and decodes all the signals.
Uses of Modem
Some of the major uses of modems are as follows –
- Nowadays every user Debit Card, Credit Card either net banking Payment through , where the modem plays a major role in transferring the data.
- Many small and large companies rely on broadband connectivity for their employees to communicate with each other. So, here broadband or Server Reliable backup is required while getting down speed of connection.
- Many large organizations have to send data to all their franchisees on a large scale every day, data is sent with a secure connection using modems.
Difference between Modem and Router
A modem is a small box that connects your device to the Internet via a cable, while a router distributes the Internet connection to your device. router Doesn’t automatically connect you to the Internet.
Through the modem you can connect your device Wide Area Network while the router connects your device to a local area network or Wi-Fi network. Router to connect your devices with each other wireless allows communication.
A modem is a networking device that is used to transfer data across a computer network with the help of a telephone line.
The function of a modem is to send and receive data across a computer network through a telephone line, cable or satellite connection.
The first commercial modem was developed by AT&T in 1962. In 1996 Dr. Brent Townshend invented the 56K modem.
Earlier the speed of the modem was measured in baud, but due to the development of computer technology, it is measured in bits per second.
The process of converting a digital signal into an analog signal is called Modulation and the process of converting an analog signal into a digital signal is called Demodulation.
The full name of Modem is Modulate / Demodulate.
