An Opened System Unit The System Unit houses all components and protects these components from dust and heat.

The Motherboard is the largest circuit card in the PC and is the central board that connects all components together.

The Power Supply convert regular AC household current into low voltage DC current for use by the computer.

The CPU Chip is the Brains of any PC and is the central data processing point.

The RAM Memory stores data that is used by the PC for immediate use. This data is lost once the PC is turned off.

The ROM Memory is that memory on a small chip that stores the bootup data. The CMOS battery keep this data in place even after the PC has been turned off.

The Hard Disk Drive is the permanent storage device in any computer system.

The CDROM Drive allow you to play those awesome games and can be used as another backup tool if you have a cd-writer.

The Drive Controller talks to your computer. Become familiar with this component and the type you have.

The BIOS Chip contains the data needed to boot-up your
PC and other critical data.

The Ribbon Cables allows data to travel from the device to the motherboard.

An Opened Monitor Stop and take a look at the components inside your monitor. NEVER open your
monitor yourself.

The Video Card is the device that transforms data from the motherboard and changes it into signals that the monitor can display.

Expansion Slots allow you to upgrade your computer by adding adapter card from devices such as a modem or scanner.

The Sound Card gives you those neat "Booms and Crackles" from those games, etc. Know all you can about this component.

The Floppy Drive though still widely used is fast
becoming a thing of the past. The cdrom and now the
DVD Drives have taken over.

The Sound Card gives you those neat "Booms and Crackles" from those games, etc. Know all you can about this component.

The Home Network use such devices as The Hub which
transfers data from one computer to another in the home.
The Hub transfer data at the slowest rate in networking.

The faster and more expensive way to transfer data is
with the use of the Router or the Switch. These devices
transfer data at the rate of 100mbs as compared to the
hub which transfers data at just 10mbs.

Wired networks in-list the help of the Cat-5 Cable as a
means of sending and receiving data. One end of this
cable is connected to the hub, switch, or router.

The other end of the cat-5 cable is inserted into the
connector of the. Adapater Card. This card is inserted
into a PCI Slot in system computer. The card maybe a Ethernet Card or may be a Wireless card when using the wireless network.

The wireless network must have a Wireless Router in order to transfer data to each computer using radio signals and eliminates the use of wires.

If you want to share Internet access with other systems
in your network, you will need either a Cable or a DSL
Broadband modem.DSL stands for Digital Subscriber
Line.

Cable Modems must use the Coaxial Cable to send
and receive internet data.
