Assume a router using RIP has 10 entries in its forwarding table at time t1. Six of these entries are still valid at time t2. Four of these entries have been expired 70, 90, 110, and 210 seconds before time t2. Find the number of periodic timers, expiration timers, and garbage collection timers running at time t1 and time t2.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
