Basic infomation on Modems and how they work.

A modem is a device that allows you to connect to the internet. Your phone line plugs into a modem and the modem plugs into your computer by ether a serial port,usb port or internally vie a PCI card slot.

With dial up modems were very important as the modem would take your normal phone line and change its signal from analog to digital so your computer could read what it was saying. The reason it does this is because your computer can’t read analog like the phones do.

Today with ADSL and other high speeds analog intent has almost been phased out but for people who don’t have money or don’t have access to ADSL still stick with it.

Modems are still used today with ADSL and other fast speed services, you even get modems that can plug multiple computers in vie a cable network and/or a wireless network.
