Transport Layer

Layer 4 of the OSI reference model is the Transport layer. The transport layer is primarily responsible for the message's process-to-process delivery. A process is a type of application program that runs on the host computer. The Transport layer's primary role is to collect data from the layer above, divide it into smaller units, transfer these data units to the Network layer, and verify that all of the parts arrive at the other end in working order. Furthermore, all of this must be accomplished quickly…

Network Layer Protocols

Network Layer Protocols Every computer on a network has a unique IP address that allows it to be identified and addressed under Network Layer Protocols. An IP address is a logical Layer-3 (Network Layer) address. When a machine restarts, this address may change. At one point in time, a computer may have one IP and at another point in time, it may have a different IP. TCP/IP supports the following Network Layer Protocols: Address Resolution Protocol(ARP) Address Resolution Protocol (ARP) is used to link the…

Network Layer Addressing

Network Layer Addressing Network layer addressing is one of the network layer's key responsibilities. The addresses on a network are always logical or software-based. The Network Layer is the third layer in the OSI model. It responds to transport layer service requests and forwards them to the data link layer. Converting logical addresses to physical addresses is the responsibility of the network layer. It chooses the best path from the source to the destination and deals with challenges like switching, routing, and data packet congestion.…
