Computer jargon means words to do with computers and surrounding topics. Knowing what these words mean can help people know more about computers. Most people use these words to discuss computer ideas, but some people use these words to impress others (also known as buzzwords).

Some examples of jargon are:

  • Disk - A place to store data.
  • Data - Information stored on a computer. The amount of data that is stored on a disk is measured with the following terms:
    • Bit - The smallest data unit, can either be a "0" or a "1."
    • Nybble - there are 4 bits in a Nybble.
    • Byte - there are 8 bits in a byte.
    • Kilobyte - There are 1024 Bytes in a Kilobyte.
    • Megabyte - There are 1024 Kilobytes in a Megabyte.
    • Gigabyte - There are 1024 Megabytes in a Gigabyte.
  • Upload - To put data on somewhere. For example, on the internet or a website, "I uploaded my pictures to Facebook."
  • Download - To take data from somewhere. For example, "I downloaded a song from iTunes."
  • Load - To get data from, or put it on, a disk.
  • Save - To put data on a disk.
  • RAM - Memory, the more the better.

  • Hardware - The solid, hand-touchable things in or that connect to a computer, like monitors, fans, CPU, etc.
  • CPU - Central Processing Unit, another name for processor.
