Can your computer boot without BIOS why Brainly?
EXPLANATION: Because, without the BIOS, the computer will not start. BIOS is like the ‘basic OS’ which interconnects the basic components of the computer and allows it to boot up. Even after the main OS is loaded, it may still use the BIOS to talk to the main components.
What do you think why CMOS is very important in BIOS Brainly?
Answer: It is the BIOS’s storage of the date, time, and system configuration details it needs to start the computer.
What is the most important role of BIOS?
BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.
Is it dangerous to update BIOS?
Installing (or “flashing”) a new BIOS is more dangerous than updating a simple Windows program, and if something goes wrong during the process, you could end up bricking your computer. … Since BIOS updates don’t usually introduce new features or huge speed boosts, you probably won’t see a huge benefit anyway.
