MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -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-2: -A complete sequence of bus actions required to perform a read or write is called a bus transaction. Most bus transactions involve two devices. The device that ini-tiates the operation is called the master. The other device (which responds to the master) is called the slave.

Detailed explanation-3: -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.

Detailed explanation-4: -The most common serial data buses include the USB, also known as the Universal Serial Bus; FireWire; Serial ATA; and Serial Attached SCSI.

Detailed explanation-5: -USB (Universal Serial Bus) is an external bus standard used for transferring data to and from digital devices.
