Internet from stands Interconnected Network is a global communication system that connects computers - computers and networks - a network of computers around the world. Every computer and network connected directly or indirectly to some of the main lines of the so-called Internet backbone and are distinguished from one another using a unique name that is commonly referred to as 32-bit IP address. Example: 202.155.4.230.
Computer and network with various platforms that have different and distinctive characteristics of each - each (Unix, Linux, Windows, Mac, etc.) to exchange information with a standard protocol known as TCP / IP (Transmission Control Protocol / Internet Protocol) . TCP / IP is composed of 4 layers (network access, internet, host-to-host transport and application) which has its own protocol.
If you have a computer at least 486 processor, Windows 95, Modem, and the phone line, then you can join the thousands of millions of other computers around the world and access a treasure trove of information on the internet.
HTTP (Hypertext Transfer Protocol)

With us can type unix telnet command from one computer to another, in other words we can do remote access (remote access). To use Telnet, we must have an IP address or domain name, and have the right to access is by login name and password. SSH (Secure Shell) is designed to replace telnet with advantages in security, operates over TCP and provides authentication and secure communications

DNS (Domain Names System)
The computers on the Internet using a standard naming format to simplify the management of computer servers on the Internet is growing rapidly. This naming system is a computer server Domain Names System (DNS). Create a DNS domain levels, which is a group of computers connected to the internet.
