A modem was a tool that converted analog and digital signals from the first form to the second and back, so that computers could transmit data to each other using analog telephone lines, and it was used to send news and military intelligence and eventually connect everyone to the Internet.
The oldest types of modems appeared since the 1920s, and at that time the main function of a modem was to transmit data types over dedicated telephone lines which are mostly used by news agencies, and this was the first form of instant messaging.
By the 1950s, modems were present in most strategic military locations, including bases and radar stations, and by 1959 the first modems for commercial use were available.
Eventually the modem was used to allow dial-up Internet connections to personal computers in the home. The first personal computer modem was created in 1977.
The modem world as we know it
In the 1980s the word "modem" referred to a device for converting a stream of digital pulses into an audible signal to be sent over a standard telephone line allowing computers to transmit information over the phone, but modems did not become a standard feature for personal computers until the mid-1990s, and as a result, "modems" became Distinguished technology among computer enthusiasts.
Modem owners defined themselves as a separate class of computer users capable of traversing the emerging sideways of cyberspace, and the networks they frequented became known collectively as the "modem world".
The modem world has developed in parallel with the ARPANET family, which was created by professional researchers in university and government laboratories.
The modem was advanced in the 1990s and its speed increased dramatically from 300 bytes/second to 56 kilobytes/second, as different types of protocols were used to compress the transmitted data without the need to increase the speed, which led to faster data transfer.
The purpose of using the modem
Modems are used to send and receive digital data between multiple computer systems. This data is then transmitted over phone lines to modems that help convert those signals back into digital form and a computer-readable format.
The modem plays a role as a digital translator that helps get all the information signals from the cable, fiber or telephone line and convert them into a form that can be accessed by your computers.
The most important functions of modems in computer networks
Data compression: To reduce the amount of time when trying to send data and to reduce error percentages in all streaming signals.
Modulation of signals: The main function of a modem is to transmit and decode all the signals that allow digital data to be sent from one node to the other nodes without causing any damage to the information.
Flow control: Each modem has a different speed for sending signals, so it can cause problems while receiving signals if you lower the speed of any device from it. This is the importance of flow control technology.
Modem Advantages
The modem is more useful in connecting the local area network to the Internet, the speed depends on the cost, the modem is widely used in the way of data communication, and it converts the digital signal into analog signal.
Disadvantages of modem
It acts only as an interface between the local network and the Internet.
There is no traffic maintenance.
The modem does not understand the intermediate operation.
Do we still need modems?
Routers and modems were traditionally two separate devices that worked together to form your home network, however with today's technology you don't necessarily need a separate modem and router, as the new modems and router combine the functions of the two devices into one powerful tool.
Do people still use modems to connect to the Internet?
Yes you can still use dial-up internet if you have a phone line and modem, and access an internet provider with dial-up service, however as more online tasks like streaming video and browsing the web become more intense it might be better to connect to high-speed internet if your available.
When did you stop using modems?
After the introduction of commercial broadband in the late 1990s, dial-up internet became less popular in the mid-2000s, and is still used when other forms are not available or when the cost is prohibitive as in some rural or remote areas.
The main purpose of using a modem is to provide access to the Internet. Also, you can connect the modem directly to your system without the need for a router.
