What is a TCP/IP? TCP/IP, Transmission Control Protocol/Internet Protocol, is a suite of communications protocols used to interconnect network devices on the Internet. TCP/IP implements layers of protocol stacks, and each layer provides a well-defined network services to the upper layer protocol. TCP and IP are the two protocols used by TCP/IP, as well as the (higher) application, (lower) data link and (lower) physical layer protocols.
What is an IP address? The internet is made up of computers exchanging information with each other using a common language known as the Internet Protocol Suite (TCP/IP). In order for the computers or devices to talk to each other they need addresses, which are a string of numbers known as an Internet Protocol or IP address. The type of IP address youâre probably familiar with is known as IPv4, and is made up of 32 bits, usually in a format like 203.57.146.214.
