What is a Modem?

There are many ways a personal electronic device can connect to the internet. They all use different hardware and each has a range of connection speeds. As technology changes, faster internet connections are needed to handle those changes. I thought it would be interesting to list some of the different types of internet connections that are available for home and personal use, paired with their average speeds. Dial-up access is cheap but slow. A modem internal or external connects to the Internet after the computer dials a phone number. This analog signal is converted to digital via the modem and sent over a land-line serviced by a public telephone network.

Network Devices

A modem is a gadget that is used to transmit digital data through an Analog system. Modems are sorted based on two criteria:. It was when a modem was first used with a computer for transmitting data to another computer. The gadget is used for modulating an Analog transporter signal to carry digital data just as for demodulating a small signal so as for decoding the digital data from the Analog carrier signal. In this article, we will explore the types of modems. Modems are used to transmit digital information via analog systems. Modulator means that converts digital signals into analog signals and sends them over telephone lines.

A modem modulator-demodulator is a device that modulates an analog signal to digital information. It also decodes carrier signals to demodulates the transmitted information. The main aim of the modem is to produce a signal that can be transmitted easily and decoded to reproduce the digital data in its original form. Modem In this difference tutorial, you will learn: What is Modem? What is a Router? How the Router Works? Routers are computer networking devices that serve two primary functions: 1 create and maintain a local area network and 2 manage the data entering and leaving the network as well as data moving inside of the network.

A modem is an electronic device that converts computer's digital information into analog carrier signals and vice versa.

By: Marshall Brain. The word "modem" is a contraction of the words modulator-demodulator. A modem is typically used to send digital data over a phone line.

Hardware devices that are used to connect computers, printers, fax machines and other electronic devices to a network are called network devices. These devices transfer data in a fast, secure and correct way over same or different networks. Network devices may be inter-network or intra-network. Some devices are installed on the device, like NIC card or RJ45 connector, whereas some are part of the network, like router, switch, etc. Let us explore some of these devices in greater detail.

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.
