The cost of getting modems depends on the speed required and can be regulated by the user.
They are helpful for the connection of the local area network (LAN) to the internet.Now, broadband modems are commonly used to connect a computer to a broadband network. These enabled computers to access the internet in the late 1990s and early 2000s. When modems first became popular, they were called dial-up modems. In simple terms, a modem is like a digital translator that converts information from a cable, telephone line, etc., to a form or language your computer can understand. In the same way, the receiver of a modem demodulates incoming signals from analog to digital form. When sending the signal out, a modem modulates it using carrier waves to encode the digital information. It is a piece of hardware that can convert digital information into a format that can be transmitted over an analog transmission medium such as a telephone line, radio, cable, or satellite connection. It is a computer hardware device that changes data strings from one format to another to facilitate faster and better transmission. What is a modem?Ī modem is a modulator and demodulator device. Modems and routers were parts of this historical evolutionary phase and continue to be relevant to us today. 10 Key Comparisons: Differences and SimilaritiesĬomputer networks and the world of information and communication technology (ICT) have evolved rapidly in the past 50 years.
