In the TCP/IP model, which layer defines the interface between software running on the computer and the network itself?

Application layer of TCP/IP model defines the interface between software running on the computer and network itself.

Explanation:

Application layer is highest level layer in both TCP/IP model and OSI model but has some difference in functionality in both models. In TCP/IP application layer performs communication through protocols and provide interface methods which help in mapping between software running on PC and network.

Application layer

Explanation:

The TCP/IP (Transmission Control Protocol/Internet Protocol) model defines four layers which are;

i. Application layer

ii. Transport layer

iii. Internet layer

iv. Network access layer

Out of these layers, the application layer is the topmost layer and defines the interface between software running on the computer and the network itself. In other words, It provides the interfaces and protocols that are needed by users to interact with the software application on the computer and the network. It also provides certain functionalities such as;

i. error handling

ii. data recovery

iii. maintenance of users' sessions and

iv. development of network-based applications.
