â€œTCP/IPâ€ refers to two networking protocols, TCP, or Transmission Control Protocol, and IP, or Internet Protocol. Â These two protocols are commonly used in computer and Internet networks and together are called â€œprotocol stacksâ€ because both are means of networking being implemented in a wide area. Â When talking about the Internet, it literally involves a wide network of computers connected to each other from different terminals and server locations throughout the world. Â One way to connect these computers is through a networking implementation called a protocol stack. For this very purpose, many of today’s computer networks implement the TCP/IP protocols, and this is considered a standard in the computer and networking industry.
The TCP/IP protocol stack is widely used today because it allows computer connectivity with specific rules and standards on how data is to be handled. Â Through this combined protocol, the formatting of data is known at the source, and the means of transmitting or routing it to other areas is also recorded. Â The TCP/IP standard protocol also secures how the data is viewed and displayed at its destination computer terminal.
In order for a TCP/IP protocol to work, all its abstraction layers must be present. Â The Ethernet layer is in charge of the communication needs in the computer network. Â The next layer involved is called the IP, or Internet layer, and this is responsible for the network connections between computers. Â The transport layer, or the TCP layer, will then handle communications between hosts. Â The last layer, called HTTP, or Hypertext Transfer Protocol, is the one that literally contains the instructions on how the data is to be handled. Â In the case of Web pages, for example, HTTP ensures that the Internet browser is efficiently communicating with the Internet server. Â With these multiple layers, the TCP/IP protocol is viewed as a stack of different standards put into one protocol suite.
