What is bus in micro computer?

A bus, sometimes also called a trunk, is an electronic. highway in a digital computer that provides a commu- nication path for data to flow between the central proc- essing unit (CPU-4. v.) and its memory and between and among the CPU and the various peripheral devices connected to the computer.

What are the types of buses in a computer?

Three types of bus are used.

• Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
• Data bus – carries the data between the processor and other components.
• Control bus – carries control signals from the processor to other components.

What is bus in a computer?

In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers.

Which bus is used for IBM PC?

Industrial Standard Architecture
The ISA (Industrial Standard Architecture) bus is commonly used in IBM-PC compatibles and is one of the most widely-used system busses. The PCI (Peripheral Component Interconnect) bus is a flexible high-performance peripheral bus that can ef- ficiently interconnect peripherals and processors of widely different speeds.

What is bus speed?

The term “bus speed” refers to how quickly the system bus can move data from one computer component to the other. The faster the bus, the more data it can move within a given amount of time.

What is function of external bus?

An external bus primarily enables connecting peripherals and all external devices to a computer. These devices can include storage, monitors, keyboard, mouse and more. Typically, an external bus is composed of electrical circuits that connect and transmit data between the computer and the external device.

What is the purpose of bus?

A bus is a subsystem that is used to connect computer components and transfer data between them. For example, an internal bus connects computer internals to the motherboard. A “bus topology” or design can also be used in other ways to describe digital connections. A bus may be parallel or serial.

What is bus full form?

In computer architecture, a bus (shortened form of the Latin omnibus, and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers.

What is bus transfer?

A bus transfer is the most effective method to send data by using a common bus system. It is constructed using common bus registers in multiple registers. The mechanism of the bus includes a collection of lines. These lines are registers of one bit each, which share only one information at a time.

How is bus bandwidth calculated?

Calculating bandwidth for a data bus is like the following in a text I read: “The bus cycle speed is 200 MHz with 4 transmits of 64 bits per clock cycle. The bus bandwidth is then 200*4*64/8=800*64/8 MBytes per second which is 6400 MBytes per second.”

What is EISA bus computer?

The Extended Industry Standard Architecture (in practice almost always shortened to EISA and frequently pronounced “eee-suh”) is a bus standard for IBM PC compatible computers. The bus mastering support is also enhanced to provide access to 4 GB of memory.

How is bus speed calculated?

Locate the model number of your computer’s motherboard and search for the manufacturer and model number on the Internet. Detailed specs of the motherboard should include the front-side bus speed, measured in MHz. You can find the memory bus speed, as well.
