TCP/IP (singkatan dari Transmission Control Protocol/Internet Protocol) adalah standar komunikasi data yang digunakan oleh komunitas internet dalam proses tukar-menukar data dari satu komputer ke komputer lain di dalam jaringan Internet Protokol ini tidaklah dapat berdiri sendiri, karena memang protokol ini berupa kumpulan protokol (protocol suite). Traditionally, IP was the connectionless datagram service within the original Transmission Management Program launched by Vint Cerf and Bob Kahn in 1974; the other being the connection-oriented Transmission Control Protocol (TCP). If no such errors happen in the physical layer, the IP protocol ensures that the transmission is terminated successfully.

The IP protocol standardizes the way machines over the Internet or any IP network forward or route their packets based mostly on their IP addresses. An IPv4 tackle consists of four numbers, every of which comprises one to three digits, with a single dot (.) separating each quantity or set of digits.

It’s endorsed that gateways are able to handling datagrams of no less than 576 bytes without having to use fragmentation. This is the remaining Time To Reside (TTL) for a datagram when it travels on the Internet. Since IP doesn’t assure dependable packet delivery over a community, TCP takes the cost of constructing the connection dependable.

Any piece of knowledge (TCP packets, in the case of a TCP/IP community) is broken into bits and placed into these packets and transmitted over the network. Here is an example of what an IP deal with may look like: 78.125.0.209.

RFC 3796 Survey of IPv4 Addresses in At the moment Deployed IETF Operations & Administration Space Standards Track and Experimental Documents. Routers talk with each other via specially designed routing protocols , both interior gateway protocols or exterior gateway protocols , as wanted for the topology of the community.
