1. A modem or broadband modem is a hardware device that connects a computer or router to a broadband network. For example, a cable modem and DSL modem are two examples of these types of Modems. Similarly, when an analog signal is received, the modem converts it back (“demodulates” it) to a digital signal.
What are the four types of modem?
The types of available modems include analog, digital subscriber line (DSL), cable and Integrated Services Digital Network (ISDN). Analog modems are used for dial-up connections. DSL and cable are high-speed broadband connections.
What is the function of modem in networking?
A modulator-demodulator, or simply a modem, is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.
What is internal and external modem?
An external modem is quiet similar to the internal modem in that it also allows access to the Internet. The external modem is an external part of the computer. The modem typically connects to the computer via a serial or USB cable, and it also needs an external power supply to operate.
What is router and its type and uses?
A router is used to transfer data packets between networks. Data from the internet is always sent through packets, and routers perform the function of directing traffic to different networks in the computer. There are wired, wireless, core, edge and virtual routers available.
What is the full form of modem?
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 function of modem and router?
Your modem is a box that connects your home network to the wider Internet. A router is a box that lets all of your wired and wireless devices use that Internet connection at once and also allows them to talk to one another without having to do so over the Internet.

How are modems used to transmit digital data?
Modems are used to transmit digital information via analog systems. The word “Modem” is derived from the term “modulator-demodulator.” The fundamental elements of a modem are to modulate an analog carrier signal to carry digital data and to demodulate a comparable signal in order to disentangle the digital data from the analog carrier signal.
What kind of modem do I need for high speed internet?
DSL modems are suitable for high-speed internet and data transfer over an ordinary phone line. ISDN stands for integrated services for the digital network is a type of communication standards for simultaneous digital transmission of voice, video data over a single wire or optical fiber.
