|
Network communication components are standardised which helps to ensure that different types of hardware and software are able to communicate.
|
|
|
Through separating the overall network communication processes it makes troubleshooting easier should an error occur.
|
|
|
To ensure that if changes are made in one layer they do not affect any other layers
|
|
|
Through dividing overall network communication into smaller, individual components it makes the software development process more straightforward.
|
|
|
All of the above

Detailed explanation-1: -To ease network engineering, the whole networking concept is divided into multiple layers. Each layer is involved in some particular task and is independent of all other layers. But as a whole, almost all networking tasks depend on all of these layers.
Detailed explanation-2: -The host-to-host delivery and finding a path to the destination are the main responsibilities of the network layer. The routing, logical addressing, fragmentation & reassembly, datagram encapsulation, error handling & diagnostics are the key responsibilities of the network layer.
Detailed explanation-3: -The primary function of the network layer is to enable different networks to be interconnected. It does this by forwarding packets to network routers, which rely on algorithms to determine the best paths for the data to travel.
