The Processor
The processor carries out functions which retrieves and processes information to and from various computer components using "bus" lines from the computer's memory to produce the required result that the user wants. All of the information is processed through the motherboard. Boolean logic is the processing language used by the processor chip to communicate bits of information throughout the computer. Boolean logic basically uses a two-value logic system of "true" and "false" to translate electrical currents into information that can be used by the system.
Motherboard
Motherboard is where all of the internal components are stored to help the communication of the system to find the relevant hardware to process from. The mother board has thousands of tiny compounds that all interact to startup any program required by the user or the system.
Graphic card
The graphics card is a hardware component whose function is to generate and output images to display. It operates on similar principles as a sound card or other peripheral devices. This is all processed through the processor and then the information travels through the motherboard and up the VGA (Video Graphics Adapter) cable then the information is displayed on the desktop by the component that provides the ability to convert display information into a signal that is sent to the monitor. The 15 pings on the VGA cable come in three rows. The table below shows what electric waves get from the computer to display the images we see.
| 1: Red out | 6: Red return (ground) | 11: Monitor ID 0 in |
| 2: Green out | 7: Green return (ground) | 12: Monitor ID 1 in or data from display |
| 3: Blue out | 8: Blue return (ground) | 13: Horizontal Sync out |
| 4: Unused | 9: Unused | 14: Vertical Sync |
| 5: Ground | 10: Sync return (ground) | 15: Monitor ID 3 in or data clock. |
BIOS
The BIOS (Basic input/output system) chip is stored on the motherboard and is used to detect all of the hardware in your system and boot the operating system. BIOS is the first operation on the system that boots when you turn on the system. The bios chip communicates through binary language which is simply zeros and ones, that is understood by the system by the processor and then is changed to information which it then communicates with all of the hardware to insure it is running correctly. Power supply The power supply to the computer communicates through the motherboard and turns on the heat sink to insure that the system doesn’t over heat and then the power supply supplies power to the rest of the computer such as the CD/DVD Rom to run the start up tests.
Port drives
The ports are located at the back of the computer and the USB ports are located at the front of the base unit. They communicate by a device interacting with the ports such as a cable, USB and PS2 device that transfers data in or out thought the bios chip and the motherboard and then displays this information on the desktop.
Network card
A network card is used to allow the system to communicate over a computer network because it has a Mac address to help the system communicate with other computers by communicating with the ports on the computer over a cable or by a wireless device this is done by the information being stored in ROM on a card. This device is located on the motherboard.
