Chapter 2

2.1 What exactly is a computer, and what are its four main functions?

2.2 What is the difference between data and information?

2.3 What are bits and bytes, and how are they measured?

  • Know abbreviation and approximate number of bytes for each of the following
    • kilobyte, megabyte, gigabyte, terabyte
  • Given size in one unit, be able to convert to another. For example, given KB, be able to convert to MB.
    • 1 KB = 1,000 B = 0.001 MB
    • 1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 B

2.4 What devices do you use to get data into the computer?

  • QWERTY vs. Dvorak keyboard
  • Different types of mice
