The Transmission Control Protocol (TCP) is one of the main protocols of the Internet Protocol Suite. TCP is part of the popular "TCP/IP" combination used by the Internet. The Internet Protocol, or IP, makes sure data on the internet gets to the right place. Then TCP makes sure the data is put in the right order, and none of it is missing. TCP also helps to control traffic on the internet so it does not get overloaded. These protocols, which are kind of like languages that computers use, are designed so that any computer, and any program (such as a Web browser or e-mail client), can use them.
