MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -What’s the data transfer rate of a typical hard drive? Because of how hard drives work-with rotating discs-and the way in which they store and access data, they are usually limited to a transfer rate of about 100 MBps–200 MBps.

Detailed explanation-2: -The data transfer rate (DTR) is the amount of digital data that’s moved from one place to another in a given time. The data transfer rate can be viewed as the speed of travel of a given amount of data from one place to another. In general, the greater the bandwidth of a given path, the higher the data transfer rate.

Detailed explanation-3: -To calculate the data transfer time: Determine the size of the data you want to transfer. Find the transfer rate of your internet connection or cable, depending on the use. Calculate the transfer time by dividing the file size by the speed.

Detailed explanation-4: -We call the part of main memory where a block being read or written is stored a buffer . Data transfers from disk to memory are handled by the system bus, not by the processor. This means that the processor is available to process data during disk I/O.
