Computer Programs

What is a Computer Program:

• Programs operate on data.
• Program are data. Von Newmann Architecture
• Programs can manipulate other programs.

]Is it the same thing as computer applications?

Computer applications are developed to perform some task.

• Bespoke system vs. general workstations

Inefficient for applications to be written directly for a given hardware platform.

• Code reuse among applications
• Need to manage multiprogramming (do you really want to put this into the application)
• Protect data, IO, etc. (can you put this into the application)
