Document Summary
There are 2 types of components involved with computer systems: Hardware components of a computer system, are the electronic and mechanical parts. Software components of a computer system are the intangible parts: the data and the computer programs. Functions of a computer: input, processing, output, storage. Processor is short for central processing unit or cpu. A particular computer, such as a intel or amd chip. The processor does the fundamental computing within the system, and directly or indirectly controls all the other components. The processor is an electronic device about a one inch square, covered in plastic. Inside the square is an even smaller square of silicon containing millions of tiny electrical parts. A processor may contain 100 thousand transistors (tiny switch with no moving parts. Ram is often called volatile memory because when the power if the computer is turned off, all information that is stored in ram is destroyed.
