Encyclopedia Definition of:bus. A shared digital pathway between resources and devices. In a computer, there are two major types: the system bus and peripheral bus. 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.

WHAT DOES BUS STAND FOR WITH REGARDS TO COMPUTERS? Report Abuse. Bus doesn't stand for anything. It's a term to describe the transfer of something. Kind of like how a school bus transfers annoying kids, the buses in a computer transfer data.he speed between the processor and RAM memory for instance is probably what your referring to. The faster the bus speed, the faster the processor can access data in RAM, which makes the computer faster.

Bus (computing) The internal bus, also known as internal data bus, memory bus, system bus or Front-Side-Bus, connects all the internal components of a computer, such as CPU and memory, to the motherboard. Internal data buses are also referred to as a local bus, because they are intended to connect to local devices.

Modbus - Computer Definition Modbus - Computer Definition A high-level protocol for industrial networks developed in 1979 by Modicon (now Schneider Automation Inc.). Providing services at layer 7 of the OSI model, it defines a request/response message structure for a client/server environment.

Encyclopedia ISA bus (Industry Standard Architecture bus) A hardware interface for connecting peripheral devices in earlier PCs. Pronounced eye-suh, ISA accepted plug-in cards for sound, display, hard drives and other connectivity. Originally called the AT bus and introduced with the IBM PC AT in 1984, the AT/ISA bus extended the PC bus from 8 to 16 bits. For several years, motherboards provided a mix of both 8-bit and 16-bit ISA slots. As PCI became popular, motherboards included only 16-bit ISA and PCI, and by the early 2000s, ISA was being replaced entirely by the PCI interface. See PC data buses and PCI.

Bus (computing) This bus is typically rather quick and is independent of the rest of the computer operations. External buses. The external bus, or expansion bus, is made up of the electronic pathways that connect the different external devices, such as printer etc., to the computer. Implementation details

WHAT DOES BUS STAND FOR WITH REGARDS TO COMPUTERS? The size of a bus, known as its width, is important because it determines how much data can be transmitted at one time. For example, a 16-bit bus can transmit 16 bits of data, whereas a 32-bitbus can transmit 32 bits of data. Every bus has a clock speed measured in MHz. A fast bus allows data to be transferred faster, which makes applications run faster. On PCs, the old ISA bus is being replaced by faster buses such as PCI.

C-Bus (protocol) C-Bus (protocol) This article is about the automation standard developed in Australia. For a similar standard based in North America, see CEBus. C-Bus is a communications protocol based on a seven layer OSI model for home and building automation that can handle cable lengths up to 1000 meters using Cat-5 cable. It is used in Australia, New Zealand, Asia, the Middle East, Russia, United States, South Africa, the UK and other parts of Europe including Greece and Romania.

Transit bus (March 2017) A transit bus (also commuter bus, city bus, town bus, stage bus, public bus or simply bus) is a type of bus used on shorter-distance public transport bus services. Several configurations are used, including Low-floor buses, high-floor buses, double-decker buses, articulated buses and midibuses.

What Determines the Speed & Power of a PC? Front Side Bus. Also known as the system bus, the front side bus is what connects the CPU to the rest of the components attached to the motherboard. Measured in MHz or GHz, the speed of the front side bus determines how quickly the CPU can communicate with the graphics card, RAM and other components. The bus speed is usually a ratio of the CPU's speed; the smaller the ratio, the the more efficient the processor.

EBUS (serial buses) In building automation, eBUS is a 2-wire digital serial data-bus communication interface used in heating and solar energy appliances, by mainly German manufacturers. It was originally proposed by the Karl Dungs company, and has since been adopted by several other manufacturers. The eBUS interface has also been used by home-automation enthusiasts to connect their domestic solar or heating system to a networked PC for monitoring or remote control.

- • Three kinds of buslines link the CPU, primary storage, and the other devices: 1. The data bus moves data to and from primary storage. 2. The address bus transmits signals for locating a given address in primary storage. 3. The control bus transmits signals specifying whether to read or write data to or from a given primary storage address, input device, or output device. • The number of bits a bus line can transfer at one time is known as bus line width. A bus line with a width of 32 will transfer a 32 bits of data at a time.

Bus Topology : Advantages and Disadvantages by Penna Sparrow. Bus Topology is the simplest of network topologies. In this type of topology, all the nodes (computers as well as servers) are connected to the single cable (called bus), by the help of interface connectors. This central cable is the backbone of the network and is known as Bus (thus the name). Every workstation communicates with the other device through this Bus.

Bus When referring to a computer, the bus also known as the address bus, data bus, or local bus is a data connection between two or more devices connected to the computer. For example, a bus enables a computer processor to communicate with the memory or a video card to communicate with the memory.

Computer memory The computer memory is a temporary storage area. It holds the data and instructions that the Central Processing Unit (CPU) needs. Before a program can be run, the program is loaded from some storage medium into the memory. This allows the CPU direct access to the program.

What is bus memory transfer? The computer has a bus where all information travels. It connects all the hardware together. The processor(cpu) calls for a piece of information and it addresses the bus to find that memory location and retrieve it for the operation that needed it. All of the memory cards are hardware plugged into the bus.

Bus For example, a computer with a 32-bit address bus can address 4 GB of memory, and a computer with a 36-bit bus can address 64 GB of memory. A bus is capable of being a parallel or serial bus and today all computers utilize two bus types, an internal bus or local bus and an external bus, also called the expansion bus. An internal bus enables communication between internal components such as a video card and memory.
