|
connected set of computer networks that all use a suite of common
|
|
|
|
|
[protocols](Network_protocols.md).
|
|
|
|
|
|
|
|
|
|
The protocols governing the communication between networks on the internet are
|
|
|
|
|
specified in the **Internet Protocol Suite**.
|
|
|
|
|
|
|
|
|
|
This combines two protocols:
|
|
|
|
|
|
|
|
|
|
- **TCP**
|
|
|
|
|
- The Transmission Control Protocol
|
|
|
|
|
- **IP**
|
|
|
|
|
- The Internet Protocol
|
|
|
|
|
|
|
|
|
|
Hence the Internet Protocol Suite is also known as "TCP/IP".
|
|
|
|
|
|
|
|
|
|
The TCP/IP is a network stack comprising four layers. From the top:
