bus meaning computer

V    In computing, a bus is defined as a set of physical connections (i.e. Its main purpose is to reduce the number of pathways communication travels by. O    There are three main types of buses: 1. The size or width of a bus is how many bits it carries in parallel.

Buses. Smart Data Management in a Post-Pandemic World. These types of buses are capable of transporting people from one destination to another destination. Like these buses, a computer bus transmits data from one location or device to another location or device. For example, an internal bus connects computer internals to the motherboard. A bus is either a parallel or serial bus, and either an internal bus (local bus) or an external bus (expansion bus).

A bus line is a subsystem used to transfer data between the insides of a computer or between multiple computers. (C ontroller A rea N etwork bus) A rugged, digital serial bus designed for industrial environments. A computer bus can transmit its data using either a parallel or serial method of communication. Internal Bus: Connects a local device, like internal CPU memory. Parallel buses transmit data across multiple wires. Looking for the definition of BUS? While a system bus is an internal path between the computer’s Central Processing Unit (CPU) and its memory, … Techopedia Terms:    The system bus, also known as the "frontside bus" or "local bus," is the internal path from the CPU to memory and is split into address bus and data bus subsets. Serial bus standards include universal serial bus (USB), FireWire or serial ATA with a daisy-chain topology or hub design for devices, keyboards or modem devices. All modern computers have at least one USB port. In computing architecture, a bus is a communication system that transfers data between components inside a computer or between computers. We’re Surrounded By Spying Machines: What Can We Do About It? The control bus carries the control and timing signals needed to coordinate the activities of the entire computer. Different kinds of data buses have evolved along with personal computers and other pieces of hardware. (Image credit: BW Folsom/Shutterstock) A PC bus, also referred as "the bus," is the path on the motherboard a PC uses to transfer data to and from the CPU and other PC … A bus is a subsystem that is used to connect computer components and transfer data between them. Related Posts. In this lesson, we'll talk about how a system bus works, what it's useful … In terms of other uses for the term “bus”, the network bus topology differs from the electrical bus setups mentioned in connection to circuit board and electrical design. The bus consists of wires that have the addressing information which describes the memory location of the data, i.e., where the data is sent in and from where it needs to be retrieved. 'business' is one option -- get in to view more @ The Web's largest and most authoritative acronyms and abbreviations resource. As connections evolve, the central concept of the bus will remain relevant. Bus design has been integral in electrical engineering, and also, as mentioned, in networking. J    An address bus is a computer bus that is used to specify a physical address. The system bus is also called the … A bus which is a collection of wire which transmit data from one part of computer to another, so system bus connects CPU to main memory on the motherboard. An internal bus enables the communication between internal components, such as a video card and memory. The bus contains multiple wires (signal lines) with addressing information describing the memory location of where the data is being sent or retrieved. For example, 100 MHz is said to correspond to perhaps 6400 MB per second in some architectures. VMEbus (VersaModular Eurocard bus) is a bus (computer data path) system, designed by Motorola, Signetics, Mostek, and Thompson CSF, that is used in industrial, commercial, and military applications worldwide. The bus acts as a highway on which data travels within a computer. For example, if a bus operates at a frequency of 200 MHz, it completes 200 million data transfers per second. I/O buses, which connect the CPU with the systems other components, branch off of the system bus. With a parallel bus, data is transmitted several bits at a time.
