Dial-Up Modems
The most important part of a dial-up internet connection is the modem. The modem is the short form of the Modulator and Demodulator which will simply make some electrical signal processing in order to convert digital signals into analog and analog signals into digital. Phone lines transmit analog signals where computers use digital signals. So modem sits between then to convert analog and digital signals via verse.
One of the most important parts of a Modem is speed.
With the popularity of modems fax-modem devices for computers are invented which can directly connect to computers. This type of modems was cheaper and easy to manage which does not require extra NIC or Ethernet card for the computer.
