MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The term direct access is often considered synonymous with random access because data is accessed randomly rather than sequentially. Direct access relies on addressing techniques that enable the operating system (OS) to identify the data’s location without having to search for the data.

Detailed explanation-2: -Random access (more precisely and more generally called direct access) is the ability to access an arbitrary element of a sequence in equal time or any datum from a population of addressable elements roughly as easily and efficiently as any other, no matter how many elements may be in the set.

Detailed explanation-3: -RAM (random access memory) is a computer’s short-term memory, where the data that the processor is currently using is stored. Your computer can access RAM memory much faster than data on a hard disk, SSD, or other long-term storage device, which is why RAM capacity is critical for system performance.

Detailed explanation-4: -Random-access devices include hard drives, CD (compact disc) writers, and DVD (digital versatile disc) RAM (random-access memory) devices. The hard drive typically has a storage capacity of 20 gigabytes (GB) and a data transfer rate of over 10 megabytes (MB) per second.
