Difference Between CMOS And BIOS
A Motherboard is an
essential piece of hardware in a computer. It enables multiple computer
components to interact with one another. CMOS and BIOS are two components on
the motherboard.
The main difference between CMOS and BIOS is that of their distinct functions.
The CMOS is a special type of computer memory that holds and maintains the BIOS configuration.
Whereas, the BIOS is a firmware, that completes device
initializing when the computer boots up and provides operations for the
operating system and other programs.
- MOS is an abbreviation for complementary Metal-Oxide-Semiconductor. The CMOS contains information about the system’s setup. It is a memory device with volatile storage. The BIOS configuration is stored and maintained in CMOS memory, which is a unique sort of memory storage. The CMOS microchip is found in a computer program’s Southbridge.
- The BIOS stands for the Basic Input-Output System. The BIOS has the function of starting up a computer. It completes device initializing when the computer boots up and provides operations for the operating system The BIOS is a software type called firmware. It has a non-volatile
