Test: BUS Structure - Computer Science Engineering (CSE) MCQ

Answer: c
Explanation: By using single BUS structure we can minimize the amount hardware (wire) required and thereby reducing the cost.

Answer: d
Explanation: By using Buffer registers, the processor sends the data to the I/O device at the processor speed and the data gets stored in the buffer.After that the data gets sent to or from the buffer to the devices at the device speed.

Answer: a
Explanation: PCI BUS is used to connect other peripheral devices which require a direct connection with the processor.

IBM developed a bus standard for their line of computers 'PC AT' called the Industry Standard Architecture (ISA).

Answer: b
Explanation: SCSI BUS is usually used to connect the video devices to the processor.

ANSI stands for the American National Standards Institute.

Answer: d
Explanation: The Z register is a special register which can interact with the processor BUS only.

In multiple bus organization, the registers are collectively placed and referred to as a register file.

The main advantage of multiple bus organization over a single bus is improved system performance and efficiency. By segregating the system into multiple buses, different types of data can be transferred simultaneously, reducing contention and improving overall throughput. This can lead to faster data transfers and better utilization of system resources. Additionally, multiple bus architectures can offer better scalability and support for more complex systems compared to single bus designs.
