Modem : --
Modem is a device that converts digital signal to analog signal (modulator) at the sender’s end and converts back analog signal to digital signal (demodulator) at the receiver’s end.
A modem is always placed between a telephone line and a computer.
A modem links home network to the Internet through Internet Service Provider (ISP).
The high speed types of data outside your home aren’t suitable for your direct use, so modems convert the data into digital Ethernet, which all the network equipment in your home can use.
The internet services that are outside your home (or business) which are supplied by your ISP are either DSL, cable, dial-up, or satellite.
Modems are often combined with a router into a single unit, which then also gives you a firewall protecting of your network from attack
