What are the 4 layers of the TCP IP model and 7 layers of the OSI model?
Rachel Young What are the 4 layers of the TCP IP model and 7 layers of the OSI model?
TCP/IP Protocol Architecture Model
| OSI Ref. Layer No. | OSI Layer Equivalent | TCP/IP Protocol Examples |
|---|---|---|
| 5,6,7 | Application, session, presentation | NFS, NIS+, DNS, telnet , ftp , rlogin , rsh , rcp , RIP, RDISC, SNMP, and others |
| 4 | Transport | TCP, UDP |
| 3 | Network | IP, ARP, ICMP |
| 2 | Data link | PPP, IEEE 802.2 |
What are the function of different layers of OSI model?
7 OSI Layers and Their Functions in Networking Physical Layer. It maintains the physical connection and defines the voltages and data rates. Data Link Layer. The data here is in the form of frames. Network Layer. The data here is in the form of packets. Transport Layer. It decides if the transmission is to take place in parallel or a single path.
How many layers are there in the OSI model?
The 7 Layers of the OSI. In the OSI model, control is passed from one layer to the next, starting at the application layer (Layer 7) in one station, and proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.
What are the characteristics of each layer of the OSI model?
OSI model layers. In this architecture, each layer serves the layer above it and, in turn, is served by the layer below it. So, in a given message between users, there will be a flow of data down through the layers in the source computer, across the network, and then up through the layers in the receiving computer.
What is the highest layer of the OSI model?
The highest layer of the OSI model, the Application Layer, deals with the techniques that application programs use to communicate with the network. The name of this layer is a little confusing because application programs (such as Excel or Word) aren’t actually part of the layer.
