Computer Systems

The area of computer systems studies the design and analysis of computers and programs that are used in practice.

• Compilers: programs that translate programs written in an easy-to-use language (Scheme, Lisp, C, C++, Java, Pascal, etc.) into machine language (the only language that actually runs on a machine).

• Operating Systems: programs that control the operation of a computer: sharing resources among different programs, providing security, and providing commonly needed utility programs.

• Data Bases: programs that store large amounts of data, can look up data on request, provide security, allow multiple users to access the same data.

• Graphics: construction of pictures from models of objects.

• Performance: predicting how fast a computer system will operate.

• Real-time Systems: programs that must respond with an answer within a limited amount of time.
