Tcp Ip Model
osi model is just a reference/guideline for network architecure,tcp/ip is the actual model we will use unlike osi refference model tcp/ip model contains 4 layers only all activities is done by protocols at each layer
osi model layers compare to tcp/ip
| OSI MODEL | TCP/IP |
|---|---|
| Application Presentation Session |
Application |
| Transport | Transport |
| Network | Internet |
| Datalink Physical |
Network Access |
Aplicaation,Presentation,Session layer combined into one layer called Application layer.
Data link layer,Physical layer combined into one layer called network access layer.
TCP/IP model is made up of protocols in each layer that protocol only make work done
diffrent protocols used in each layers
Application Layer: HTTP,DNS,DHCP,FTP
Transport Layer: TCP,UDP
Internet: IPV4,IPV6,ICMP4,ICMPV6
Network access: PPP,Frame Relay,Ethernet
