Organization of a Computer System

As shown in Figure 1.1, the major high-level components of a computer system are:

1. Hardware, which provides basic computing resources (CPU, memory, I/O devices).

2. Operating system, which manages the use of the hardware among the various application programs for the various users and provides the user a relatively simple machine to use.
3. Applications programs that define the ways in which system resources are used to solve the computing problems of the users (compilers, database systems, video games, business programs).
