What you'll learn

Each question helps you build key knowledge and skills.

  • 1Storage units scale up from bits to bytes to kilobytes, megabytes, gigabytes and terabytes, with each step usually multiplying by 1024 in computing.
  • 2Converting decimal numbers to binary means finding which column values from 128 down to 1 add together to make that number.
  • 3Binary addition works like normal addition but carries over into the next column whenever a column totals 2 or more.
  • 4A left shift multiplies a binary number by 2 for each place shifted, while a right shift divides it by 2, dropping any remainder.
  • 5Hexadecimal is used as shorthand for binary because each hex digit exactly represents four binary digits.
