Why are modems required when two computers need to exchange data over standard telephone line?

Modem, an acronym for modulator/demodulator, is a device that allows one computer to “talk” with another over a standard telephone line. To transmit digital data, the sending modem must first modulate, or encode, a computer’s digital signal into an analog signal that can travel over the phone line.

Why are modems needed for telephone communication?

Modem is a hardware component/device which can connects computer and other devices such as router and switch to internet. Modems converts or modulates the analog signals coming from telephone wire into digital form i.e in form of 0 s and 1 s.

Why are modems needed?

A modem is a very important piece of network hardware that allows a computer to send and receive data through a telephone line or cable connection. In simple words, it’s the device that connects a computer to the Internet.

What is a modem when and why are modems necessary What is a cable modem and how does it differ from a traditional modem?

A cable modem is a peripheral device used to connect to the Internet. It operates over coax cable TV lines and provides high-speed Internet access. Since cable modems offer an always-on connection and fast data transfer rates, they are considered broadband devices.

How does modem work in data transmission?

A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a electrical signal that can be transmitted easily and decoded reliably.

How does a modem help data transmission?

A modem attached to a computer converts digital data to an analog signal that it uses to modulate a carrier frequency. This frequency is transmitted over a line, frequently as an audio signal over a telecommunications line, to another modem that converts it back into a copy of the original data.

What are modems in data communication?

Modem is short for “Modulator-Demodulator.” It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. It converts or “modulates” an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize.

What is the role of modem in electronic communication?

What does modem do in a computer?

The sole purpose of the modem is to provide you with internet access. If you were to only have one internet-connected device with an Ethernet port (such as a desktop computer), you could connect the modem directly to your computer with no need for a router.

What is role of modem in networking?

What is modem What are the modem standard?

A standard modem is a small box that connects your devices (computers, set top boxes, etc.) to the Internet using cables. In order to enable a wireless (Wi-Fi) connection in your home, your modem must be paired with a separate device called a router. A router is a device that works with your modem.
