TCP-IP or TCP/IP

Have you ever wondered exactly how all the computers talk to each other over the Internet? TCP-IP stands for "transmission control protocol/Internet protocol" and all computers on the net must speak it. TCP-IP has always been the standard language used by UNIX machines to talk to each other and as it was UNIX machines that started the Internet all computers connecting to the Net must speak it. Versions of TCP/IP are now available for all major operating systems.
