MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In computer architecture, a bus (shortened form of the Latin omnibus, and historically also called data highway or databus) is a communication system that transfers data between components inside a computer, or between computers.

Detailed explanation-2: -A data bus can transfer data to and from the memory of a computer, or into or out of the central processing unit (CPU) that acts as the device’s “engine.” A data bus can also transfer information between two computers.

Detailed explanation-3: -Address bus-carries memory addresses from the processor to other components such as primary storage and input/output devices. The address bus is unidirectional . Data bus-carries the data between the processor and other components. The data bus is bidirectional .

Detailed explanation-4: -A databus is a data-centric software framework for distributing and managing real-time data in intelligent distributed systems. It allows applications and devices to work together as one, integrated system. The databus simplifies application and integration logic with a powerful data-centric paradigm.

Detailed explanation-5: -The front side bus ( FSB ) represents one of the most important communication bus that connects some of the most vital components of the system. And hence, the FSB is also referred as system bus. The front side bus connects the computers central processing unit ( CPU ) with the main system memory RAM .
