Answer #1

In the TCP/IP model we have 5 layers :

Application Layer

Transport Layer

Network Layer

Data Link Layer

Physical Layer

Now

Servers/Hosts have all the layers in them

Routers have 3 layers namely Physical Layer, Data Link Layer and Network Layer

Switches have 2 layers namely Physical Layer and Data Link Layer
