The TCP/IP model differs slightly in the seven-layer Open Systems Interconnection (OSI) networking model designed after it, which defines how applications can communicate more than a network.
TCP/IP model layers
The TCP/IP model differs slightly in the seven-layer Open Systems Interconnection (OSI) networking model designed after it, which defines how applications can communicate more than a network.
TCP/IP model layers
TCP/IP functionality is split into four layers, because both versions include specific protocols.
- The applying layer provides applications with standardized data exchange. Its protocols range from the Hypertext Transfer Protocol (HTTP), Ftp (FTP), Publish Office Protocol 3 (POP3), Simple Mail Transfer Protocol (SMTP) and straightforward Network Management Protocol (SNMP).
- The transport layer accounts for maintaining finish-to-finish communications over the network. TCP handles communications between hosts and offers flow control, multiplexing and reliability. The transport protocols include TCP and User Datagram Protocol (UDP), that is sometimes used rather of TCP for special purposes.
- The network layer, also known as the web layer, handles packets and connects independent systems to move the packets across network limitations. The network layer protocols would be the IP and also the Internet Control Message Protocol (ICMP), which is often used for error reporting.
- The physical layer includes protocols that operate only on the link — the network ingredient that interconnects nodes or hosts within the network. The protocols within this layer include Ethernet for neighborhood systems (LANs) and also the Address Resolution Protocol (ARP).
Need for TCP/IP
TCP/IP is nonproprietary and, consequently, isn’t controlled by single company. Therefore, the web protocol suite could be modified easily. It works with all os’s, therefore it can talk to every other system. The web protocol suite can also be compatible with lots of different computing devices and systems.
TCP/IP is extremely scalable and, like a routable protocol, can determine the best path with the network.
A brief history of TCP/IP
The Defense Advanced Studies Agency (DARPA), the study branch from the U.S. Dod, produced the TCP/IP model within the 1970s to be used in ARPANET, a large area network that preceded the web. TCP/IP was initially created for the Unix operating-system, and contains been included in all the os’s that came after it.
