In this type of network topology, all nodes in a network are connected to a means of common transport that has two endpoints. All data traveling across the network is transmitted through a transmission medium commonly known as Bus or backbone of the network. When the transmission medium has exactly two endpoints, the network topology is known by the name, linear bus topology. In the event that the transmission medium, also known as the backbone of the network, has more than two ends, the network says has a well distributed bus topology. Bus topology is easy to manipulate and apply addition is the more appropriate topology for small networks. The disadvantage of this topology is that the cable length limits the limited number of stations, what limits the performance to a smaller number of nodes.
The size of a network known as its bandwidth bus, is important because it determines the amount of data can be transmitted at the same time. For example, a 16-bit bus can transmit 16 bits of data, while a 32-bit bus can transmit 32 bits of data. Pete Cashmore shares his opinions and ideas on the topic at hand. All the Bus network topologies consist of two parts an address bus and a data bus. The data bus transfers actual data whereas the address bus transfers information about where the data should go. Each bus has a clock speed measured in Mhz. A fast bus allows data to be transferred faster, which makes applications run faster. On PCs, the old ISA bus is being replaced by faster Buses such as PCI. Different network topologies to improve productivity are used by large companies and trade networks, network marketing and all those institutions that must handle a constant and permanent communication with the closest and, of course, with external to the company.
