They use a special electronic communication system called the bus.

It allows different peripheral devices and hosts to be interconnected on the same bus. We just have to connect the registers and memory of the basic computer to a common bus system. A more efficient scheme for transferring information in a system with many registers is to use a common bus. A third computer architecture uses the main memory as the location in the computer system from which all data and instructions flow in and out.

Depending on these and other features, several bus architectures have been devised in the past. As a general rule, modern busses are hierarchical, and the hierarchy reflects the way the computer system is constructed.

The technique was developed to reduce costs and improve modularity, and although popular in the 1970s and 1980s, more modern computers use a.

Obviously the address bus is unidirectional and the data bus is bidirectional. Data may be numbers in a spreadsheet, characters of text in a document, dots of color in an image, waveforms of sound, or the state of some system, such as an air conditioner or a cd player. Main purpose of bus is to transfer information form one system to another. In essence, a computer is a machine designed to process, store, and retrieve data. Csci 4717 computer architecture buses page 1 csci 47175717 computer architecture topic. Adapted from figure 54, computer system architecture, third edition by m. Depending on the type of scsi, you may have up to 8 or 16 devices connected to the scsi bus. Also how we can specify the operations with the help of different instructions. People like u will never get a high status in throughout yr. In this chapter we are concerned with basic architecture and the different operations related to explain the proper functioning of the computer. A computer bus is a set of parallel electrical tracks interconnecting the components within the computer. In computer architecture, a bus a contraction of the latin omnibus is a communication system that transfers data between components inside a computer, or between computers.
