What you'll learn

Each question helps you build key knowledge and skills.

  • 1Computers store everything as binary digits, called bits, which can only be 0 or 1.
  • 2A group of 8 bits is called a byte, and bytes are combined to measure storage in kilobytes, megabytes and beyond.
  • 3To convert binary to decimal, you add up the value of each column where there is a 1, using the column headings 128, 64, 32, 16, 8, 4, 2, 1.
  • 4Hexadecimal is a base 16 system that uses digits 0 to 9 and letters A to F, and it is often used as a shorter way to write binary.
  • 5Text, images and sound are all converted into binary so that a computer can store and process them.
