What are BIOS and CMOS? Differ these.
Hello Dear,
Thanks for sharing.
Dear the CMOS stands for Complementary Metal oxide Semi-conductor.
It is a ROM Chip placed on the motherboard.
BIOS stands for Basic Input / Output system.
This is system software. It has all the settings to control the hardware attached to the motherboard. We can control any hardware from this BIOS.
This “BIOS” is installed in the CMOS chip.
I hope you understood now.
Thanks

What are BIOS and CMOS? Differ these.
Hi Saul,
More often these two, BIOS and CMOS are used interchangeably. The BIOS (Basic Input/Output System) contains the instructions on how the computer system boots. It is used to configure the systems hardware like enabling hardwares in the motherboard for example USB hosts and IDE/SATA controllers. Setting the boot device sequence. Can be accessed by pressing F2 or F8 (but varies depending on the manufacturer) before the OS is loaded or started.
CMOS (Copper-Metal Oxide Semiconductor) contains the system settings and is powered by the CMOS battery. It allows the BIOS to store information or settings that have been configured.
Hope your enlightened by these details. Feel free to ask if you have any clarifications.
Thanks
