Backup or save system/Data from computer.

A CD/DVD Drive is a device

that is connected to the PC’s

motherboard via a cable. It

gets power directly from the

computers (PSU)

The main purpose of a hard drive is for data storage.

For a computer system to properly function, it needs a storage unit to store and install data.

You can save Software

Documents

Photos/ music

A hard drive is a fixed disk drive that

stores digital data onto magnetic

surfaces.

IDE HARD DRIVES attach to the mother

board using a ATA cable.

SATA HARD DRIVES attach using a SATA

cable or Ribbon.

It gets power directly from the

computers (PSU)

The computer case holds and protects the computer components within the case.

Each case is different depending on the hardware inside the case.

The power supply pulls the required amount of electricity and converts the AC current to DC current.

It regulates the voltage to eliminate spikes and surges common in most electrical systems.

The PSU sits inside the computer

case.

It provides power to every

component within the case either

directly or indirectly.

Each component has a specific

cable coming from the PSU.

RAM is a memory that the microprocessor uses to store data during processing.

When a software application is launched, the executable program is loaded from hard drive to the RAM.

However RAM will loose all data on shutdown unlike a H/D

RAM is needed because hard drives are too slow to operate with the speed of a microprocessor.

Memory units or (RAM) are placed

in to specific slots on the computer

motherboard.

RAM comes in different forms

however every PC will need some

form of RAM to operate.

To process all data within your computer.

The better the processor the faster your machine will run.

The processor sits on the motherboard and is attached to every part of your computer.

The CPU (central processing

unit) is in charge of processing

data. It is also known as the

processor or microprocessor.

Data travels through various

components of the computer

before it reaches the CPU for

processing. It starts at the hard

disk drive, then to the RAM and

finally to the CPU.

The main role of a motherboard is to attach all components to the processor.

For a computer system to properly function, it needs to have all parts communicating with each other.

The motherboard can be seen as the backbone of a computer.

The Motherboard is a printed circuit

board containing the principal

components of a computer or other

device, with connectors for other circuit

boards to be slotted into.

There are several different ways a printer can connect to the computer.

USB

CAT 5

Serial port

An external piece of hardware that is

responsible for taking computer data

and generating a hard copy of that

data.

Printers are one of the most used

peripherals on computers and are

commonly used to print text, images,

and photos.

Can connect to a computer network in remote areas.

This card will fit into the motherboard and with the relevant software will connect to a wireless signal.

A wireless PC card is a gadget that

enables wireless connectivity to the

internet.

This adapter will have the capacity

to fit into the computer via a PC

Card or PCI slot

A keyboard is an important device that allows a person to enter symbols like letters and numbers into a computer.

It is the main input device for most computers.

A mouse is a device that controls the movement of the cursor on a display screen.

Both devices can be attach to a pc in many ways

Keyboards and mice come in many

different varieties. Whether it be

an internet keyboard, wireless

combo, or you’re looking for a

gaming set, all these options are

available.

There are 3 types of mice

A computer Monitor is a device

that displays signals on a

computer screen.

• Monitor's come in all different

shapes and sizes.

• Monitors get their power from a

240v wall socket.

• They are attached via VGA /dvi lead

or HDMI cable direct to the

computers motherboard.
