• You should have encountered most of the information in chapter one in CSCI 125.
• But you should read chapter 1 in any case.
• We will cover parts of this chapter as we progress through the other portions of the book.
• Some highlights
  • A computer is a programmable electronic device that can store retrieve and process data.

    • Or source
    • The output of a compiler is an execuatable
  • An editor is a program used to put text into a file
    • More on this later
  • Read about the parts of a computer
  • Read about problem solving, more on this later
