摘要：TCP / IP (Transmission Control Protocol) is a set of protocols that govern datacommunication between computers on the Internet network. So, if computersusing TCP / IP and is connected to the Internet so that computer cancommunicate or connect with other computers around the world who areconnected to the Internet. Differences in type and computer systems is not aproblem, and the protocol TCP / IP was found or taken for free at no cost byanyone. On a network that is built with TCP / IP (eg: Internet), for each stationis allocated a unique identifier in the form of four-byte address, called an IPAddress, with the addressing of 4 bytes, it is possible there are 4,294,967,296fruit station and IP addresses are grouped into five classes, namely: Class A,Class B, Class C, Class D and Class E. IP addresses are 32-bit binary numbersseparated by a dot every eight bits, for example: 00001010.01010001.00000001.00100000, and the computer can only understand the language like this. But we give the IP address on a computer is not in the form of binary numbers because it is hard to read, but with numbers is also called dotted decimal or decimal notation (dotted decimal notation). Example: 132.92.121.1. And addresses will be converted to decimal is binar.
