1. loading the operating system
   initiating the microprocessor
2. running applications

The BIOS provides instructions to the microprocessor for how to access the operating system.

1. hardware
   software
2. operating system

Along with your operating system and applications, the BIOS is the third type of software your computer needs to work successfully.

1. on a hard disk
   on a Flash memory chip
2. in a device driver

The BIOS is normally stored on a Flash memory chip on the computer's motherboard.

1. device drivers
   interrupt handlers
2. peripheral component interconnects

When you turn on your computer, BIOS loads the interrupt handlers, which act as translators between the hardware components and the operating system.

1. 34
   64
2. 124

The 64 bytes of RAM located on the CMOS chip provide detailed information particular to your system.

1. accessing your e-mail
   logging on to the Internet
2. booting up your computer

Incorrect CMOS settings may prevent your computer from booting up.

1. system time and date
   Internet provider
2. security

Common options included in CMOS setup include setting the time and date, setting passwords for security and configuring hard drives.

1. interrupt handlers
   device drivers
2. drive chips

Device drivers identify base hardware components such as the keyboard, mouse and hard drive.

1. buying an older computer
   getting rid of RAM
2. copying it into RAM

Since BIOS is constantly intercepting signals, it's usually copied, or shadowed, into RAM to run faster.

1. microprocessors
   parallel ports
2. BIOS chips

Almost every desktop and laptop computer in use today contains a microprocessor as its central processing unit.
