Network topologies and their benefits

There are several ways to set up connections in a network. Each of these setups, known as topologies, have several advantages and disadvantages.
       The first topology is the bus topology. In this setup, all the computers are connected to one main communications line called the bus. One advantage of this topology is the relative ease of actually setting up. This is the easiest of the three main topologies to set up as all you need to do is hook up a computer to the line if you want another one on the network (easy to expand). Also, it is the cheapest topology to set up because only one cable is necessary. The main disadvantage of this topology is that if there is a problem with a connection/the cable, all computers on the network are effected. Also, moving data between computers takes a longer time than the other topologies and the length of the cable limits the size of the network.

       The second topology is the ring topology. In this setup, the computers are connected to each other in a ring from one computer to the next. The advantages of this topology include faster data transfer than that on the bus topology and the fact that they are very orderly networks. Disadvantages include the fact that the necessary adapter card is very expensive and that if one computer malfunctions, the rest may experience difficulties.

       The third (and final for this post) topology is the star topology. In this network, each computer is connected to a central switch or hub rather than to each other. The main advantage of this is that if one computers experiences difficulties, none of the other computers on the network are effected. Also, data transfer is fast and removing parts is fairly simple. The disadvantages include the network's dependence on the proper functioning of the central hub/computer and the high cost of the necessary wiring.
