Individuals connecting from home typically dial in to an internet service provider (ISP) using a modem over regular telephone lines. Once connected, you can send information or requests over the internet. You can requests a web page, for example, by typing its internet address (called a URL).
Data sent over the internet is divided into packets. Each packet has destination and origin information.
An Internet service provider (ISP) has a permanent connection to the internet and provides temporary connections to others for a fee. ISPs use lines leased from local telephone companies to connect to regional host computers.
