you will learn about the seven layers of OSI model and their functions
If network communications need
to happen with out any trouble, many problems must be solved.
Coordinating all these problems are so complex and not easy to manage.
To make these tasks smooth, in 1977 the International Standards
Organization (ISO) proposed the Open Systems Interconnection (OSI)
network model. The Open Systems Interconnection (OSI) model breaks down
the problems involved in moving data from one computer to another
computer. Open Systems Interconnection (OSI) model categorizes these
hundreds of problems to Seven Layers. A layer in Open Systems
Interconnection (OSI) model is a portion that is used to categorize
specific problems.
