Transmission Control Protocol
The Transmission Control Protocol and Internet Protocol Layers refers to the communication protocols that enable use to do anything over the internet. There are four layers. In the Network Interface Layer things like sending information between hosts on the same local network and translating data from higher layers are done. The layer right above that would be the Internet Layer where data is packaged into packets, receive incoming packets of data, and addressing and transmitting packets occur. Then there is the Transport Layer this layer is responsible for end-to-end communication on the network. In short, the transport layer collects message segments from the application and transmits the to the nest layer.
Physical Layer – hubs, cables, modems, and repeaters.
Data Link Layer – bridges, switches, NIC’s,
Network Layer – routers, brouters
Transport Layer – gateways, firewalls,
Application Layer – PC’s, smartphones, servers
The TCP/IP Protocol suite was developed in the 1960’s and recognized throughout the world after 1983. As for the OSI reference model it was also recognized throughout the world in 1983. Some key similarities between the TCP/IP and OSI Model is that they describe how data is transmitted between devices on a network. Both models also divide the networking concepts into layers. The ideas about how data is broken down into smaller pieces and passed from layer to layer is the same as well. Another similarity is that these models are used to troubleshoot various networking problems. Both are modular and each layer represents a separate set of functions and protocols. Some of the ley differences between the two would be that the OSI model is a more elaborated model where each layer has separate functionality. Unlike the TCP IP model, it does not combine any layers. The OSI has 7 layers, and the TCP IP has 4 layers. The TCP/IP model is more geared towards networking hardware and software used on the internet as to the OSI models is more general and can be applied to any type of network.
