Input Device

Digital Cameras

This is a camera taking pictures in a digital form and some have video capacity. Important is the Mega Pixel of the camera and memory cards. Example: Use in art class room for instant reference of a specific captured picture where the light source doesn’t change. Benefits: User can take a picture of landscape and finish painting later keeping all the information. Challenges: Some cameras are not user friendly. Mega Pixel (under 8 MP) are not high enough to have a clear picture and the picture is flat so sometimes not enough information.

Graphics Table

Also called digital table or digitalizes that convert line sketches into digital equal for the table. Example: Used in art class for capturing sketches to convert into digital format. Architects and designer have more precise control than with a mouse. We could not afford to use one in our art class. Benefits: Educators could use them to enhance the lesson by adding comments, drawings and directional arrows to clarify concepts. Challenges: Software is expensive and using the table on the table but looking on the screen has some challenges for some learners to coordinate.


They are a often built into the computers and otherwise easy to install. Example: Used in foreign language class, students can hear themselves talk. Or, sound of any kind can be added for example a power point with the picture of a bird and the sound of it. Benefit: Can be easily used by teachers for audio tutorials, students’ speech tests, or recorded experiences that can be converted into a MP3. Students may have less anxiety talking in microphone then in front of class. Challenges: Students can be intimidated and freeze up by talking into a microphone. Maybe a technical problem that distorts a voice. Teachers need to speak slowly so that all students can process information.

Pen Input devices

Input device to include handwritten information and gestures. Can be assisting PDA and table PC. Example: Great can be used for math teachers for written work processed math problems. Also used by UPS, etc. Benefits: Math class, less use of paper and faster access and active participation in class for students and educator. Challenges: Can be expensive and not compatible with programs.

Electronic White Boards

It is an interactive, multiple media white board classroom display that allows teacher and/or students to interact with the computer through a touch sensitive board on which the computer screen is projected. Example: In the classroom setting, the art history teacher can show embedded in text right away pictures from the internet and can search database for original documents. Benefits: Very interactive to have multiple personalities involvement and great participation in class. Content of the lesson can be easily saved, edited, or printed. Can also given to students who were absent of class, or students’ that needed to reinforce information. Challenges: Costs are still very high and not all the schools can afford to give all the classrooms electronic white boards.

Touch Screen

Is a computer monitor screen that responds to the touch of a human. Example: Can be used for students that have difficulties writing with keyboard or use a mouse. Benefits: Easy and fast to use in simple and straightforward displays as in a hotel lobby or airport for information. Challenges: Can not handle large amounts of data needed for some applications.

Output Devices

Data Projection Units

To get information from the computer and displays; the same as computer screen. Example: Connected computer with LCD can projects information directly to the wall. Use a foreign language movie in class. Benefits: Many benefits and a variety of unique futures and capabilities. High quality speakers can be added. Challenges: Projection screen are very expensive and difficult to hang up. Has glare and hard to view. They can easily disappear.

Scan Converter

Displayed through an anolog (video) converter. Example: Can watch computer screen on television. Benefit: Low cost. Challenges: Small display area and poor quality. Not all the TV’s have the capacity to use a scan diverter.


A lot of computers have built in speakers and others have external components. Example: Important component in watching a movie, hearing a historical figure, giving a speech or listening to music. Benefits: Great for auditory learner and listening to your own recorded voice and pronunciation in foreign language class. Challenges: Can disrupt a class if everybody is not listening to the same sounds at same time.

New node

Listening device for individual use. Example: Have students listening to different speed and segments in a foreign language lab. Benefits: Allows students to listen to sounds without bothering other students. Challenges: Easy broken and lost.


Printing displayed or saved documents and pictures. Example: Student can easy print out a research paper. Benefits: Students has a hard copy of assignment. Challenges: Cost of paper and cartilages.

Basic Components of Computer

Hard drive This is where you store all your documents, music, and pictures. The bigger the hard drive the more storage available. RAM Random Access Memory enables one to access information faster. Ram can make the computer faster because every time you log off it gets cleaned out. Microprocessor The microprocessor is the part that gets the entire component working together. It senses information, completes tasks and puts the software to work.
