Output Devices
Output devices are things we use to get information OUT of a computer.
Here are some examples of output devices.
Monitor - A monitor is the screen on which words, numbers, and graphics can be seem. The monitor is the most common output device.
Compact Disk - Some compact disks can be used to put information on. This is called burning information to a CD.
NOTE: A CD can also be an input device.
Printer - A printer prints whatever is on the monitor onto paper. Printers can print words, numbers, or pictures.
Speaker - A speaker gives you sound output from your computer. Some speakers are built into the computer and some are separate.
Disk Drives - A disk drive is used to record information from the computer onto a floppy disk or CD.
Floppy Disk - A floppy disk is used to record information on. The information is stored on the floppy disk and can be used later or used on another computer.
Headphones - Headphones give sound output from the computer. They are similar to speakers, except they are worn on the ears so only one person can hear the output at a time.
Input Devices
Input devices are things we use to put information INTO a computer.
Here are some examples of input devices.
Note: An APPLICATION is a type of computer program.
Some applications are word processing, spreadsheets, databases, and games.
Camera - most cameras like this are used during live conversations. The camera transmits a picture from one computer to another, or can be used to record a short video.
......
Compact Disc (CD) - CDs store information. The CD can then be put into another computer, and the information can be opened and added or used on the second computer.
Note: A CD-R or CD-RW can also be used as an OUTPUT device.
Keyboard - The keyboard is a way to input letters or numbers into different applications or programs. A keyboard also has special keys that help operate the computer.
Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications.
Digital Camera - A digital camera can be used to take pictures. It can be hooked up to a computer to transfer the pictures from the camera to the computer. Some digital cameras hold a floppy disk, and the floppy disk can be taken out of the camera and put directly into the computer.
Drawing Tablet - A drawing tablet is similar to a white board, except you use a special pen to write on it and it's connected to the computer. Then the word or image you draw can be saved on the computer.
Microphone - A microphone is used to record sound. The sound is then saved as a sound file on the computer.
Scanner - A scanner is used to copy pictures or other things and save them as files on the computer.
Disk Drive - A disk drive can hold a CD or a floppy disk. It reads the information on the disk so that the computer can use it.
Joystick - A joystick is used to move the cursor from place to place, and to click on various items in programs. A joystick is used mostly for computer games.
Touch Screen - A touch screen is a computer screen or other screen that you can touch with your finger to enter information. Examples of touch screens include a smart board, a microwave, a dishwasher, or an ATM at a bank.
Bar Code Scanner - A bar code scanner scans a little label that has a bar code on it. The information is then saved on the computer. Bar code scanners are used in libraries a lot.
