When client machines communicate with servers on a network, it is known as c lient-server networking . Instead, each machine on the network is functioning as both a server and a client at the same time. For example, if Joe traveled around his office building frequently, but required a computer no matter where he was in the building, he could go to any client computer and use his one username and password to get on the network. For my last bit of networking info, I would like to discuss topology. Network topology is the physical media setup of a network.
Topologies can vary and often intersect with eachother.
All of these topologies have their disadvantages and advantages, and all are viable options for a network. The first topology, bus, is one of the most common topologies in networking. With a bus topology, each computer is connected in a linear fashion to one long cable, which either terminates or continues at the end. At each end of the cable where the line of connected machines ends, a terminator must be applied. If the cable is not terminated, any data passing over the cable will bounce back and forth along the an endless loop.
