COMPUTER NETWORKING

Detailed explanation-1: -In a network, each point-to-point link is technically a hop, and hop count pertains only to the number of network devices between the start and end nodes. Hop count only considers devices which perform routing. As a result, routers and firewalls which perform routing are all considered in hop counts.

Detailed explanation-2: -HOP counts refer to the number of devices, usually routers, that a piece of data travels through. Each time that a packet of data moves from one router (or device) to another-say from the router of your home network to the one just outside your county line-that is considered one HOP.

Detailed explanation-3: -A router and firewall are two different things, and the router is hardware to provide connections to various devices. As against, a firewall resides between the network and the system to filter the data going in and out of the system. However, both can be used for filtering the traffic with an access control list.

Detailed explanation-4: -A hop is a computer networking term that refers to the number of routers that a packet (a portion of data) passes through from its source to its destination.

Detailed explanation-5: -RIP uses the number of hops, or hop count, to determine the best possible route to a host or network. The term hop count is also referred to as the metric. In RIP, a hop count of 16 means infinity, or that the destination cannot be reached.
