Question

If there is a single path between the source host and the destination host, do we need a router between the two hosts?​

Answer 1

Answer:

In computer networking, including the Internet, a hop occurs when a packet is passed from one network segment to the next. Data packets pass through routers as they travel between source and destination. The hop count refers to the number of intermediate devices through which data must pass between source and destination.

Since store and forward and other latencies are incurred through each hop, a large number of hops between source and destination implies lower real-time performance.
