A bus is a common pathway through which information flows from one computer component to another. ?the communication paths that are revolutionizing interactions between microprocessor systems. Recommended for you The author provides a basic theory of busses and draws examples and applications from real bus case studies. In computer architecture, a bus (a contraction of the Latin omnibus [citation needed], and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers.This expression covers all related hardware components (wire, optical fiber, etc.) trailer << /Size 354 /Info 311 0 R /Root 314 0 R /Prev 324777 /ID[<3f50c542898e313c9ddd8d561c857b7e>] >> startxref 0 %%EOF 314 0 obj << /Type /Catalog /Pages 307 0 R /Metadata 312 0 R /PageLabels 305 0 R >> endobj 352 0 obj << /S 1470 /L 1653 /Filter /FlateDecode /Length 353 0 R >> stream endobj List and give the functions of computer buses. 0000005343 00000 n They will make you ♥ Physics. A bus connects various components in a computer system. The layout of a computer's buses and parts is called its bus architecture. Academia.edu is a platform for academics to share research papers. Print Book & E-Book. A bus consists of the connection media like wires and connectors, and a bus protocol. Citations per year. The control bus, like the other buses, is simply a set of connections among the parts in the computer. 0000004208 00000 n There are several books which cover individual busses, but none which provide a complete guide to computer busses. The ……………….. organization consists of number of cross points that are placed at intersection between buses and memory module paths. The author provides a basic theory of busses and draws examples and applications from real bus case studies. Think of this as a traffic cop. 3. Control bus B. Control Bus The motherboard's control bus manages the activity in the system. 0000044995 00000 n Gursharan Singh Tatla 6 It is a bidirectional bus, as it also transmits response signals from the hardware. 0000042108 00000 n Functions: - Data bus – carries data to and from the CPU. Types of Buses in Computer Architecture. This pathway is used for communication purpose and it is established between … The Primary Buses There are generally two buses within a computer. To be used with S. Dandamudi, “Fundamentals of Computer Organization and Design,” Springer, 2003. 0000004789 00000 n A data bus can transfer data to and from the memory of a computer, or into or out of the central processing unit (CPU). 0000045243 00000 n 0000004767 00000 n Color-coding of the table groups buses with similar structures or function. CPU communicates with other devices on motherboard like memory, expansion cards, co-processor and keyboards via bus lines. Introduction to computer Bus 2. Types of Computer Bus. The control bus carries the control and timing signals needed to coordinate the activities of the entire computer. Morris Mano 1 Lecture#04 Computer Register and System Buses A Register is a very fast computer memory, used to store data/instruction in-execution.t is a group of flip-flops with each flip-flop capable of storing one bit of information. 3 0 obj A set of electric paths through which computer (CPU) send and receives data and instructions to and from different components of computer is called computer bus. Thus buses can be categorize into: Internal buses: The processor uses several internal buses to interconnect registers and the ALU. 0000005046 00000 n 0000001171 00000 n It allows different peripheral devices and hosts to be interconnected on the same bus. this section, we discuss the main features of the bus protocols used for transferring data. There are several books which cover individual busses, but none which provide a complete guide to computer busses. External buses: are used to interface with the devices outside a typical processor system. 0000005651 00000 n 0000041479 00000 n In the language of computers, the term buses actually refer to the system present within the hardware of the computer.This system is helpful in moving the data and without these buses; the computer can do calculations but lack the capability of moving the resulting information to any of the output device.
