What are the four TCP/IP Layers?

A	Application
B	Transport
C	Link
D	Application

Explanation:

Detailed explanation-1: -The four layers of the TCP/IP Model include Network Access Layer, Internet Layer, Host to Host Layer, and Application Layer.

Detailed explanation-2: -The application layer is the highest abstraction layer of the TCP/IP model that provides the interfaces and protocols needed by the users. It combines the functionalities of the session layer, the presentation layer and the application layer of the OSI model. It facilitates the user to use the services of the network.

Detailed explanation-3: -The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net-work, transport, and application layers. Not all layers are completely defined by the model, so these layers are “filled in” by external standards and protocols.

Detailed explanation-4: -The TCP/IP model comprises four layers: the network access layer, the internet layer, the transport layer, and the application layer (going from bottom to top).
