MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -RAM is volatile memory used to hold instructions and data of currently running programs. It loses integrity after loss of power. RAM memory modules are installed into slots on the computer motherboard. ROM (Read-Only Memory) is nonvolatile: data stored in ROM maintains integrity after loss of power.

Detailed explanation-2: -RAM is a volatile memory that holds the files we’re operating on temporarily. The ROM is a non-volatile memory that holds our computer’s instructions indefinitely.

Detailed explanation-3: -Non-volatile memory is typically used for the task of secondary storage or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost.

Detailed explanation-4: -Volatile memory (like SRAM and DRAM) requires power to maintain data, while non-volatile memory (like NAND Flash and NOR Flash) does not require power to retain data. Because of the differences between DRAM and SRAM, DRAM is better suited for main memory and SRAM is better suited for processor cache.

Detailed explanation-5: -RAM is a type of volatile memory, i.e., it loses the data stored in memory once the power supply is lost. Static RAM and Dynamic RAM are two types of RAMs. In SRAM, the data is stored in transistors.
