I want to know, what is OSI model?

Hello,

OSI stand for open system interconnection model and it is ISO standard that covers all the aspects of network communications.

It is a layered framework for the design of network systems that allows communication between all types of computer system.

OSI model introduce in late 1970s.

Simply OSI model is not a protocol; it is a model for understanding and designing network architecture.  

7 Layers in OSI model:

1.  Physical Layer
2. Data link layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer

Thank You

John Major.
