COMPUTER FUNDAMENTALS

Detailed explanation-1: -The network layer is layer 3 in the OSI model, and it is responsible for connections between different networks.

Detailed explanation-2: -The transport layer is responsible for transferring data across a network and provides error-checking mechanisms and data flow controls. It determines how much data to send, where it gets sent and at what rate. TCP within the TCP/IP suite is the best-known example of the transport layer.

Detailed explanation-3: -Router. A router directs data requests from one network to another. Routers examine incoming packets to determine the appropriate destination IP address and then forward the packet to that destination. A router can also enable internet access through its connection to a modem, or as a combined modem-router.

Detailed explanation-4: -Router. Routers help transmit packets to their destinations by charting a path through the sea of interconnected networking devices using different network topologies. Routers are intelligent devices, and they store information about the networks they’re connected to.

Detailed explanation-5: -The protocol layer just above the internetwork layer is the host-to-host transport layer. It is responsible for providing end-to-end data integrity and provides a highly reliable communication service for entities that want to carry out an extended two-way conversation.
