MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Detailed explanation-2: -Flash memory is a long-life and non-volatile storage chip that is widely used in embedded systems. It can keep stored data and information even when the power is off. It can be electrically erased and reprogrammed.

Detailed explanation-3: -Non-volatile memory is the type of computer memory that can hold the saved data even if the power is off. Few examples of non-volatile memory are EEPROM (Electrically Erasable Programmable Read-Only Memory), ROM, hard disk, floppy disk, etc.

Detailed explanation-4: -Examples include hard disks, magnetic tape and optical disks. Magnetic storage devices (e.g., hard disks, magnetic tape, floppy disks, etc.)
