MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Flash is technically a variant of EEPROM, but the industry reserves the term EEPROM for byte-level erasable memory and applies the term flash memory to larger block-level erasable memory. Flash memory consists of a transistor and a floating gate that stores the electric current.

Detailed explanation-2: -Flash memory is a type of EEPROM designed for high speed and high density, at the expense of large erase blocks (typically 512 bytes or larger) and limited number of write cycles (often 10, 000).

Detailed explanation-3: -The pen drive uses EEPROM electrically erasable program Read only memory to store data. EEPROMs are flash memory devices. When connected to pc the driver of the pen drive configures the pen drive as a storage disk. Thus, ’pen drive’ is called as a ‘flash drive’

Detailed explanation-4: -Flash memory is a type of electronically-erasable programmable read-only memory (EEPROM), but it can also be a standalone memory storage device such as a USB drive. It is a non-volatile memory chip used for storage and for transferring data between a PC and other digital devices.

Detailed explanation-5: -A USB flash drive–also known as a USB stick, USB thumb drive or pen drive–is a plug-and-play portable storage device that uses flash memory and is lightweight enough to attach to a keychain.
