When talking about the physical elements of the Internet, the term redundancy refers to:Question 28Answera.multiple duplicate devices and paths in a network built so that data can be rerouted if a breakdown occurs.b.delays in messages caused by the uneven flow of information through the network.c.transmitting multiple copies of a single packet to safeguard against data loss.d.the use of tiered high-speed switching computers to connect the backbone to regional and local networks.

Network redundancy provides for network reliability. What does it mean to have network redundancy?a.Two full networks run in tandem; if one fails, traffic is sent to the otherb.When the network fails, there is an alternate network path to route datac.The network is straightforward and allows for one reliable main network pathd.When the network fails, data is stored as a backup until the network can be restored
