COMPUTER FUNDAMENTALS

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. Read-only memory (ROM) is nonvolatile: Data stored in ROM maintains integrity after loss of power.

Detailed explanation-2: -Data of RAM is very volatile, it will exist as long as there is no interruption in power. Data present in Read-Only Memory (ROM) is not volatile, it is permanent. Data will remain unchanged even when there is a disruption in the power supply.

Detailed explanation-3: -Data in memory is the most volatile. This includes data in central processor unit (CPU) registers, caches, and system random access memory (RAM). The data in cache and CPU registers is the most volatile, mostly because the storage space is so small.

Detailed explanation-4: -NVRAM (non-volatile random-access memory) refers to computer memory that can hold data even when power to the memory chips has been turned off. NVRAM is a subset of the larger category of non-volatile memory (NVM), which includes storage-class memory based on NAND flash.
