MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Because cloud storage keeps everything online, it doesn’t consume any of your computer’s secondary storage, allowing you to save space. This option boasts significantly larger storage capacity than physical options such as USB flash drives, hard disk drives (HDDs) and solid state drives (SSDs).

Detailed explanation-2: -A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.

Detailed explanation-3: -Backing storage is used to store programs and data when they are not being used or when a computer is switched off. When programs and data are needed they are copied into main memory but also still remain on backing storage.

Detailed explanation-4: -Detailed Solution. The correct answer is Hard Disk. A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electromechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material.

Detailed explanation-5: -Non-volatile storage is storage that maintains the data even when there is no electricity powering the device. An example is a hard disk drive (HDD) or solid state drive (SSD) that holds all of the data saved to your computer. There is other non-volatile storage, such as DVDs or flash drives.
