A computer alone is not enough to access the internet. In addition to Web browser software,the computer needs specific hardware and a connection to an Internet Service provider to view Web pages.
First , a computer must have a modem or network card. A modem is a device that enables a computer to connect to a network. A modem converts data to audio tunes and transmits the data over phone line s.A network card also called a network interface card (NIC),is hardware that allows a computer to connect to the Internet through a network or high speed Internet connection,such as a local area network (LAN),cable modem or a Digital Subscriber Line(DSL).
After ensuring that a computer has a modem or a network card (most computers come with one or both of these ), the next step is to register with an INTERNET SERVICE PROVIDER (ISP) . Computers connect to an ISP using a Modem and a phone line ,LAN, DSL etc.
Bandwidth and cost are two considerations when deciding which commercial ISP service to use.Bandwidth refers to the amount of data can be transferred through a communication medium in a fixed amount of time. Different ISPS offers different types of speed connections called broadband connections.
