FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Repeaters are network devices operating at physical layer of the OSI model that amplify or regenerate an incoming signal before retransmitting it. They are incorporated in networks to expand its coverage area. They are also known as signal boosters.

Detailed explanation-2: -Explanation: The network interconnection devices that operate at the network layer are usually called routers.

Detailed explanation-3: -Repeater operates only on the physical layer i.e. first layer of the OSI model.

Detailed explanation-4: -IP (Internet Protocol)-works at the network layer. It handles addressing, packet-switching, route selection and error control for communication.

Detailed explanation-5: -Explanation: In the OSI model, network layer is the third layer and it provides data routing paths for network communications. Error control is a function of the data link layer and the transport layer.
