A. Parts of the Computer System:

1. CPU(Central Processing Unit) or Processor
-execute computer programs.

2. Storage:

a. Main Memory- directly accessible to the CPU.
b. Secondary Memory-not directly accessible by the CPU.

3. Peripheral Devices:

a. Input Devices-used to provide data and control signals to an information processing system.

b. Output Devices- used to communicate the results of data processing carried out by an information processing system to the outside world.

B. System:

Is a set of interacting or interdependent entities, real or abstract, forming an integrated whole. The concept of an 'integrated whole' can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the set and elements not a part of the relational regime.

A system is a fundamental concept of system theory, which views the world as a complex system of interconnected parts. We determine a system by choosing the relevant interactions we want to consider plus choosing the system boundary —– or, equivalently, providing membership criteria to determine which entities are part of the system, and which entities are outside of the system and are therefore part of the environment of the system. We then make simplified representations (models) of the system in order to understand it and to predict or impact its future behavior.

C. Examples of Platforms:

a. Operating system platform examples
-Microsoft Windows
-Linux
-Mac OS backward compatibility via Rosetta
-WINE platform to behave like Microsoft Windows

b. Software platform examples
-Java - JDK and JRE
-NET Framework - operating system dependence (MS Windows)
-Mozilla Prism XUL and XUL Runner
-Adobe AIR

c. Hardware examples
-Mainframe computerwith its custom operating system, say an IBM.
-Midrange computer
