The EEPROM (Electrically Erasable Programmable ROM) on the BIOS Software Motherboard is stored on the ROM chip.

What is CMOS?

The CMOS i.e. Complementary Metal Oxide Semiconductor is a battery, which stores all the settings in the BIOS, and with the help of this, the BIOS starts the Computer Booting Process.

You must have seen that even after computer OFF, its time & date does not change.

This is because the setting of Time & Date is stored in the BIOS and it runs with CMOS Battery. If the CMOS battery of a computer is bad, then after plugging in, it takes a little time to start the computer and the time & date is also reset.

What does the BIOS work for?

As I mentioned above, the BIOS helps in starting the computer and it configures all the Input / output devices. But with this the BIOS does many more important tasks that help the computer to run well. for example..
