Importance of TCP/IP

Introduction

TCP / IP - acronym for Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol) - a pre-agreed standard that is used to exchange data between two nodes (computers on the network), and no matter what platform and what these computers between their network. TCP / IP serves as a bridge that connects all the nodes in the network together, for which it won its popularity. TCP / IP have arisen as a result of research funded by ARPA (Advanced Research Project Agency) - a special branch of the U.S. government in the 1970s. It was conceived as a common standard, which will unite all the networks into a single virtual "network of networks" (internetwork). Thus was created the Internet, as a result of conversion of an existing conglomerate of computer networks, which bore the name of the ARPAnet, using TCP / IP.

The name "TCP / IP" is associated with two protocols: TCP and IP. But TCP / IP - it's not just these two protocols. This is a family of protocols, combined under one - IP-protocol. This family includes protocols which interact with the IP protocol and use it to build their data feeds. It is very TCP, and UDP, ICMP, telnet, SMTP, FTP and many others.

Description and Analysis

It is responsible for transferring large amounts of data over a network using IP-protocol, separated by parts and collecting together again at the end of the route. If you are sending through TCP / IP data is encoded and divided into TCP-packets (segments), so that then there was the possibility to restore them when unpacking a case of damage. There is whole science of this coding. A simple example of the same security package is a TCP-parity (which is added to each ...
