FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -ROM (Read-Only Memory) is nonvolatile: data stored in ROM maintains integrity after loss of power. A computer Basic Input Output System (BIOS) firmware is stored in ROM. While ROM is “read only, ” some types of ROM may be written to via flashing, as we will see shortly in Section “Flash memory.”

Detailed explanation-2: -4 ROM. Non-volatile memory is memory that retains its values even when power is removed. Earlier forms of non-volatile memory included various forms of read-only memory (ROM).

Detailed explanation-3: -At its core, non-volatile memory is “byte addressable, ” random access memory (RAM) for computers that retains data even in the absence of power. Byte-addressable memories facilitate access to data at the individual byte level. Computer memory involves the “devices used to store information for use in a computer.”

Detailed explanation-4: -FRAM is a nonvolatile storage memory that retains its data even after the power is turned off. However, similar to commonly used DRAM (Dynamic Random Access Memory) found in personal computers, workstations, and non-handheld game-consoles, FRAM requires a memory restore after each read.

Detailed explanation-5: -Cache memory and RAM are types of Volatile memory. Non-volatile memory, on the other hand, is static. It remains in a computer even after a user switches it off. HDD and ROM are types of non-volatile memory.
