II. Basic Hardware Components of Computer Systems
A computer system consists of hardware and software components. As important
as the software which are the programs that run the computer, the hardware is the physical
equipment such as the case, storage drivers, keyboards, monitors, cables, speakers and
printers that builds up and let the software run.
It is important to learn about these components as these will be the basis before you
handle equipment especially in disassembling and assembling a computer system.

Computer Systems
The complete computer made up of the CPU, memory and related electronics (main
cabinet), all the peripheral devices connected to it and its operating system.
- Computer systems fall into two broad divisions: clients and servers.
- Client machines fall into three categories from low to high end: laptop, desktop and
workstation.
- Servers range from small to large: low-end servers, midrange servers and
mainframes.
