A technician has just finished assembling a new computer. When the computer is powered up for the first time, the POST discovers a problem. How does the POST indicate the error?

• 
  It issues a number of short beeps.

• 
  The LED on the front of the computer case flashes a number of times.

• 
  It places an error message in the BIOS.

• 
  It locks the keyboard.

What is a function of the BIOS?

• 
  enables a computer to connect to a network

• 
  provides temporary data storage for the CPU

• 
  performs a check on all internal components

• 
  provides graphic capabilities for games and applications

A technician has assembled a new computer and must now configure the BIOS. At which point must a key be pressed to start the BIOS setup program?

• 
  before the computer is powered on

• during the Windows load process

• 
  during the POST

• after the POST, but before Windows starts to load
