Third Generation Languages (mid 1950’s)

 Think of a person who works at the United Nations  As soon as these people get a phrase of what a person is talking about, they put it into the language which they are interpreting

 At the end of the day, they might not even know what the speech was about

(That is not their job)

Programming Languages

Third Generation Languages (mid 1950’s)  There are two classes of program languages

  • Those that are interpreted
  • Those that are translated or compiled
    • BASIC started as an interpreted language
    • The compiler makes a few ‘passes’ through the code
      • It first checks syntax
      • It next checks simple logic
      • It sets-up variable tables
    • The compiler creates a separate executable (.exe) or command file (.com)
    • These file are machine language files

  • If, for example, we want to find the average age of a class, we need to know the procedures involved
    • We need to add every persons age in a class together
    • We then need to divide the sum of every persons age by the number of people in the class
    • The result is the average age of the class

  • Program Editors : Packages for source code creation which check key words, structures as the program is typed in
  • Debuggers : a computer program that is used to test and debug other programs.

  • Page description language that creates hypertext and hypertext linkages

Hypertext Mark-up Languages (HTML)

  • Hyperlinks: allows control to be given to other parts of a document or to any document on the WWW
