On the other hand, most computer systems employ fewer layers than the OSI model requires. Why not use a smaller number of layers? What are some of the disadvantages of using fewer layers?

Answer

OSI
The Open Systems Interconnection model is a conceptual model that characterizes and standardizes the communication operations of a telecommunication or computing system without respect to its underlying internal structure and technology.

 

Why not use a smaller number of layers

The seven layers of the OSI are Physical, Data Link, Network, and Transport. The rest is made up of session/presentation/application layers.

Although most computers employ this method, the session layer and presentation layer's work is minimized, allowing them to be merged with the application layer in the same way as the TCP/IP model does, and the data link layer and physical layer are likewise handled as a single unit.

 

Advantages of using few layers
Because there are fewer layers, they may be able to increase speed while lowering costs by reducing the number of devices that must be deployed in the network.

Adding more layers to a single layer, on the other hand, increases the load on that layer, which can lead to overheating and make it difficult to resolve the problem later. It is feasible to lower the number of layers employed, but the amount of labor and duties performed by each layer will increase.
