bus topology


Networks employing a bus topology use a common physical connection for communication. That means the physical media is shared between stations. When one station transmits on the bus, all devices hear the transmission. If more than one device transmits at the same time, the two transmissions will collide with each other and both transmissions will destroy each other.
When two or more of these devices attempts to access the network bus at the same time, some method must be used to prevent a collision (CSMA/CD). Historically, bus networks used coaxial cable as their medium of transmission. Token Bus, Ethernet (Thinnet and Thicknet) are common examples of bus topologies. Although some installations of Ethernet using coaxial cable still exist, all modern installations now use a hub and spoke or star topology.

Computer Buses

Computer Buses   A computer system consists of different devices.CPU must be able to communicate with all devices. The devices are connected together by a communications channel called bus. A bus consists of a set of communication lines or wires. It is used to move a large amount of bits in the form of electrical pulses from one unit to another. The bus is used to connect the following units: Central Processing Unit Control Unit  Arithmetic and Logic Unit Main Memory ( RAM, ROM) Input / Output Devices Bus is a common path to transfer data and commands between CPU, memory and input / output devices.It is also used to send or receive data from secondary storage.The capacity of a bus depends on the number of data lines in it.A bus with 16 lines can carry 16 bits or 2 bytes at a time. A bus with 32 lines can carry 32 bits or 4 bytes at a time . Types Of  Buses Different types of buses are as follows: 1. Data Bus 2.Addres...
