1THIS IS A COMPUTERCOMPILED BY RICHARD AMOAKO, CO-FOUNDER OF PROJECT GOODWILL AFRICA, A YOUTH EMPOWERMENT ORGANIZATION
2THIS IS A COMPUTER SYSTEM A basic Computer system should have at a minimum a mouse, a keyboardand a monitor.
3THIS IS A SYSTEM UNITThe system unit is the main part of a computer system. Inside the system unit are all the various components and parts that allow the computer to perform its functions.On the outside of the system unit, peripheral devices such as the keyboard, mouse and monitor connect to the Computer. The System Unit should not be confused with the CPU (Central Processor Unit) which is inside the System Unit.
4THIS IS A KEYBOARDThe keyboard is an input device. It allows you to input new information as well aschange existing information on the Computer.
5THIS IS A MOUSEThe mouse in an input device. You use the mouse to tell the Computerwhat to do by moving, pointing and clicking on programs, applicationsor icons. The mouse also helps you to navigate program menus.
6THIS IS A MONITORThe monitor is an output device. It shows you what the Computer is doingby displaying visual information and images to the screen.When you move the mouse, type on the keyboard or click on a program tolaunch, the monitor shows you what is happening in real time.
7THIS IS A PRINTERA printer is an output device that allows you to create readable copies of textand data on paper. You can also use the printer to print pictures and variousimages.A printer connects to the Computer through a parallel printer port or a USBport on the System Unit.
8THIS IS A PAIR OF COMPUTER SPEAKERS The computer speakers allow you to listen to sound coming out ofthe computer. It is therefore an output device.The speakers are normally connected to the computer through a sound port on the back or front of the System Unit. Some speakers connect to a USB port instead.
9THE COMPUTER MICROPHONE Computer microphones come in various shapes and sizes. A microphone is an input device that helps you record your own sound onto the computer.Some people use the microphone to chat over the internet.
10THIS IS A CD-ROM DRIVEThe CD-ROM drive reads information on CDROM disk or media. Theinformation on the media may be pictures, songs, games, videos, anapplication program etc.The CD-DRIVE drive may be internal or external to the System Unit.
11THIS IS A CDROM DISKThe CD media is what you will place in the CDROM drive. The informationon the media will be retrieved by the CDROM drive.
12THIS IS A USB DISKA USB disk , also known as a pen drive, is a removable storage device.You can use it to store information from the computer. It makes it convenientto carry your files from one place to another.To access the USB disk you would connect it to a USB port on the system unit.
13THIS IS A HARD DISKThe hard disk is a storage media inside the Computer’s system unit. Itis used to store various kinds of information such as documents, picturesvideos and applications.The hard disk will only be seen if the System Unit is opened.
14THIS IS A FLOPPY DRIVE3¼ inches floppy disksA floppy drive is a component of the main system unit. It is used to storeinformation on a floppy diskette. A 3¼ inches floppy disk can store up to 1.44MBof information.
15This is a floppy diskette The floppy disk is a removable storage media. It makes it convenient to carryyour files from one Computer to another. A 3¼ inches floppy disk can store upto 1.44MB of information.
16THIS IS A SCANNERA scanner is used to scan or take snapshots of images on paper andtransfer those images into the Computer for storage or editing or both.
17THIS IS A WEBCAMA webcam is used to capture images and transmitted directly over the internet for other internet users to see.A webcam connects directly or wirelessly to the computer.
18THIS IS A MOTHERBOARDThe motherboard is located inside the System Unit. All the other parts of theComputer including the CPU, Memory, hard drive are connected to motherboard.
19THIS IS A CPUCPU is short for Central Processor Unit. The CPU is the brain of the Computer. It interprets andprocesses the instructions that the user submits to the Computer through input devices orapplications and programs. The speed at which the CPU processes instructions to perform it’stasks is measured in Megahertz (MHz) and Gigahertz (GHz). [ 1Ghz = 1000Mhz ]The CPU is located on the motherboard inside the Computer.
20THIS IS A MEMORY CHIPThe Computer uses memory also known as RAM to temporarily store informationneeded by the CPU to perform its tasks while the Computer is running. Informationin RAM is said to be volatile or temporal because all the information is lost whenthe Computer is turned off.
