Plz download ebook of computer architecture schaums outline computer architecture. Computer buses page 7 the following diagram shows how a bus can be subdivided into functional units such as an address bus that specifies a location in memory that is to be read from or written to, the data bus that copies data from one point in the system to another, and the control bus. As a general rule, modern busses are hierarchical, and the hierarchy reflects the way the computer system is constructed. Beautiful, but need some more computer mcqs, related to networking, network security, and information security. A computer system is basically a machine that simplifies complicated tasks. A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent, and a control bus to determine its operation. One synchronous bus has a clock cycle time of 50 ns with each bus transmission taking 1 clock cycle. 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.

The data bus, which is a bidirectional path, carries the actual data between the processor, the memory and the peripherals. 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. We just have to connect the registers and memory of the basic computer to a common bus system. An improvement on the single shared central bus architecture. In this architecture, the different components of the machine share a common 32bit bus through which they communicate. The processor, main memory, and io devices can be interconnected by means of. Just like a passenger bus that carries people, the computer bus carries lots of information using numerous pathway called circuit lines.
