Today\'s networks are based on the TCP/IP protocol suite:

Can you briefly explain for me the origins of TCP/IP

If you can also send me some references to read from I would really appreciate.

Solution

Origins of TCP/IP:

The TCP/IP protocols were originally developed as part of the research network developed by the United States Defense Advanced Research Projects Agency (DARPA or ARPA).

The ARPAnet, was designed to use a number of protocols that had been adapted from existing technologies. But they all had flaws or limitations, either in concept or in practical matters such as capacity, when used on the ARPAnet. The developers of the new network recognized that trying to use these existing protocols might eventually lead to problems as the ARPAnet scaled to a larger size and was adapted for newer uses and applications.

Therefore, they came up with a layered architecture which provides reliable end to end connection. This architecture is called TCP/IP.
