Why buses are important in computer explain the role of all type of buses?

A bus is a high-speed internal connection. Buses are used to send control signals and data between the processor and other components. 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.

What is the role of I O buses in the system?

The system bus, also called the memory bus, makes a connection between the CPU and the main memory of the computer that resides on the motherboard. Input/Output (I/O) or expansion buses are responsible for connecting the peripheral devices (mouse, keyboard, flash drives) to the Central Processing Unit (CPU).

What are the characteristics of bus in computer organization?

A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.

Which is the best function of the expansion bus?

An expansion bus provides an input/output pathway for transferring information between internal hardware, such as RAM or the CPU, and expansion devices such as a graphics card or sound card.

What do you mean by bus in relation to computer?

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. This expression covers all related hardware components (wire, optical fiber, etc.)

What is bus system in computer?

The computer system bus is the method by which data is communicated between all the internal pieces of a computer. It connects the processor to the RAM, to the hard drive, to the video processor, to the I/O drives, and to all the other components of the computer.

What is PCI bus in computer architecture?

PCI Bus Architecture: PCI is a local computer bus for attaching hardware devices to a computer. The PCI bus connects the processor memory subsystem to the fast devices and an expansion bus that connects relatively slow devices such as a keyboard and serial and parallel ports.

What is bus system in PLC?

PLCBUS (Communication Protocol) or PLC-BUS is a power-line communication protocol for communication between electronic devices used for home automation. It primarily uses power line wiring for signaling and control. PLCBUS is similar to the X10 (industry standard) power line communication protocol.

What is a bus in computer system?

Why expansion bus is required?

Why does a computer need an expansion bus? Expansion slots on the motherboard are standardized connections that allow the installation of any device not soldered to the motherboard. By providing this connection to the expansion bus, computers can be customized to meet the requirements of the user.

What is expansion bus Why is it required Explain any three expansion bus standards?

External bus or Expansion bus allows the CPU to talk to the other devices in the computer and vice versa. It is called that because it’s external to the CPU. Address bus allows the CPU to talk to a device….
