Computer Network Model
Different Computer Network Models
- Computer Network Model: It is the structure and model or design which is used to perform communication between two networks.
- OSI Reference Model
- TCP/IP Model
- OSI: It stands for ‘Open System Interconnection’ . It is the general purpose communication model in the computer network earlier days.
- It is an ‘open source’ structure which means that it can be openly used for any environment and network easily for communication purpose.
- It is a seven layered structured architecture.
- TCP/IP: It stands for ‘Transmission Control Protocol/Internet Protocol’ .
- It is a four layered architecture model. Different layer is responsible for different task.
- OSI: It stands for ‘Open System Interconnection’ . It is the general purpose communication model in the computer network earlier days.
- Layered Architecture:
- Various computer network models like OSI, TCP/IP work on the layered architecture, which means that there will be various layers of the model.
- There are different layers of a single model will be responsible for various different work and tasks.
Let us take an example.
- In Layered Network Architecture, an entity of layer N uses only services of layer N-1.
