1. Introduction
Personal Computer
The P.C (Personal Computer) allows many tasks to be undertaken which would otherwise not be possible. From typing a letter to surfing the net the computers versatility has meant many homes and workplaces rely on the computer for everyday tasks. This book delves into the mysterious world of how the computer actually works inside those boxes. Although understanding the precise operation of computer hardware requires detailed technical knowledge, understanding the basics of how a computer works does not.
System Tower
The computer system comprises of several boxes. The main computer is housed in a rectangle box. Inside this box is the motherboard and disk drives.
The drives connect to the motherboard through special ribbon cable. The cable contains many separate wires moulded into a flat wide cable.
Monitor
The monitor is housed in a separate box and plugs into the main system box.
Todays slim line monitors are a far cry from the old large cumbersome cathode ray tube monitors.
Keyboard
Mouse and Mat
The Keyboard and Mouse are housed in smaller boxes that connect to the main system box.
They connect either with a cable to the main system box or by using a wireless receiver that plugs into a USB port of the system box.
Scanner
Additional items like a printer and scanner also connect to the main system box. They connect either with a cable to the main system box or using a wireless receiver that plugs into a USB port of the system box.
Windows
Switching the power on loads the operating system (O.S). In the case of a P.C this would usually be a version of Windows. The O.S is normally loaded from the computers hard drive.
Programs and data files are stored on the hard drive. Selecting them from the Windows Start menu starts programs.
2. Inside the P.C
Case
To protect the fragile P.C (personal computer) against damage it is housed in a case. Different case styles are available. A tower case is useful where desktop space is limited as it can go on the floor. The disadvantage here is accessing the CD ROM/DVD drives to change disks. A desktop case as its name implies sits underneath the monitor and allows disks to be easily accessed. The case is plastic or metal.
