Internet
Internet is a global collection of network. The Internet is
a network of networks, linking computers to computers sharing the TCP/IP
protocols.
It is a "network of networks" that consists of
millions of smaller domestic, academic, business, and government networks,
which together carry various information and services: electronic mail, online
chat, file transfer, interlinked Web pages and other documents of the World
Wide Web.
A Hierarchy of Networks From a single computer to LAN, From
LAN to ISP and ISP to WWW.
ISP: Internet service provider Malaysian ISP’s and type of

Internet protocol
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 way that someone who wants to use a service talks with that service.
The "someone" could be a person, but more often it is a computer
program like a Web browser. An Internet Protocol address (IP address) is a
numerical label that is assigned to devices participating in a computer network
that uses the Internet Protocol for communication between its nodes. An IP
address serves two principal functions: host or network interface
identification and location addressing.
Internet protocol
A typical IP address looks like this:
216.27.61.137
To make it easier for us humans to remember,
IP addresses are normally expressed in decimal format as a
dotted decimal number like the one above.
But computers communicate in binary form.
TCP/IP
Transmission Control Protocol/Internet Protocol, the suite
of communications protocols used to connect hosts on the Internet. TCP/IP uses
several protocols, the two main ones being TCP and IP. TCP/IP is used by the
Internet, as the de facto standard for transmitting data over networks.
