A brief overview of TCP/IP communications

Explains the TCP/IP network protocol, how it works, client / server connections, and more general information.

While TCP/IP communications (and collecting data from TCP/IP devices) can appear to be daunting at first, it is actually a very simple communication tool.

What is TCP/IP and where did it come from?

TCP/IP stands for “Transmission Control Protocol / Internet Protocol”. It is basically a network protocol that defines the details of how data is sent and received through network adapters, hubs, switches, routers and other network communications hardware. It was developed by the US department of defense for the purpose of connecting government computer systems to each other through a global, fault tolerant, network. The defense department network was opened up to research institutions and eventually the general public to create what is now the Internet. The TCP/IP protocol was also placed in the public domain so that any software company could develop networking software based on the protocol. Because it is the primary protocol used on the Internet, and it is in the public domain, it has become the most popular networking protocol throughout the world and is therefore well supported by almost all computer systems and networking hardware.
