The BIOS is special software that interfaces the major hardware components of your computer with the operating system. It is usually stored on a Flash memory chip on the motherboard, but sometimes the chip is another type of ROM.
Is BIOS a software or firmware?
A computer’s BIOS (basic input/output) is its motherboard firmware, the software which runs at a lower level than the operating system and tells the computer what drive to boot from, how much RAM you have and controls other key details like CPU frequency.
Is a BIOS a system software?
BIOS, in full Basic Input/Output System, computer program that is typically stored in EPROM and used by the CPU to perform start-up procedures when the computer is turned on.
Is motherboard a hardware or software?
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

Does the BIOS test hardware?
The BIOS performs a “system inventory” of sorts, doing more tests to determine what sort of hardware is in the system. Modern BIOSes have many automatic settings and will determine memory timing (for example) based on what kind of memory it finds.
Which type of software is BIOS?

What does a BIOS file look like?
The BIOS is the first piece of software your PC runs when your turn it on, and you usually see it as a brief flash of white text on a black screen. It initializes the hardware and provides an abstraction layer to the operating system, freeing them from having to understand the exact details of how to deal with devices.
What is hardware give five examples?
