Details: TCP IP Protocol
The TCP IP protocol is actually a suite of
communication protocols rather than a single protocol. Originally, the
TCP IP protocol contained the two protocols, TCP and IP for which it is
named. Now, it contains an entire collection of protocols which are
organized into four layers, the application layer, the transport layer,
the Internet layer, and the link layer. TCP stands for Transmission
Control Protocol and IP stands for the Internet Protocol. Understanding
these two protocols and how they work together helps you to get a better
understanding of the TCP IP protocol. In order to send information over
a TCP/IP network (such as the Internet), it’s important to identify each
computer on the network. This is done by assigning each computer its own
unique IP address. The Internet Protocol then breaks the data into small
“packets” which are then sent to the specified computer based on its IP
address. These packets travel across the Internet independently and
eventually arrive at their final destination. The Transmission Control
Protocol takes these packets and reassembles them. Most computers are
preconfigured to work with the TCP IP protocol. For example, the TCP IP
protocol is a core component of Windows computers and it cannot be
uninstalled.
