Since its beginning in 1969, the Internet has grown from four host computer systems to tens of millions.

You may use a modem and dial a local number to connect to an Internet Service Provider (ISP). At work, you may be part of a local area network (LAN).internet

The ISP may then connect to a larger network.

Most large communications companies have their own Point of Presence (POP). The POP is a place for local users to access the company’s network, often through a local phone number or dedicated line. These POP’s connect to a network of high level networks through Network Access Points (NAPs).

Internet Protocol: IP Addresses

Every machine on the Internet has a unique identifying number, called an IP Address. The IP stands for Internet Protocol, which is the language that computers use to communicate over the Internet. A protocol is the pre-defined.

The Domain Name System (DNS) maps text names to IP addresses automatically.

When you send an e-mail message, you use a domain name to do it.

Example, the Uniform Resource Locator (URL) “http://www.isearchthe.net” contains the domain name isearchthe.net. So does this e-mail address: example@isearchthe.net.

Every time you use a domain name, you use the Internet’s DNS servers to translate the human-readable domain name into the machine-readable IP address.
