Question

Topic 1 ; In your own words, explain the difference between the OSI model and the TCP/IP model. Why do you think there are two models?

OSI stands for Open Systems Interconnection. It has 7 layers Physical layer, Data Link layer, Network layer, Transport layer, Session layer, Presentation layer, and Application layer. Each layer performs its task independently.

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It has 4 layers named as Physical layer, Network layer, Transport layer, and Application layer. It also can be used as a communications protocol in a private computer network

These models have a few differences which include;

The OSI model has 7 layers whereas the TCP/IP has 4 layers
OSI is vertically approached while TCP/IP is horizontally approached
OSI is low in usage while TCP/IP is mostly used
In the OSI model, Delivery of the package is guaranteed whereas Delivery of the package is not guaranteed in the TCP/IP model
