Printers not only produce their output on paper, they can also be used to produce their output on transparencies for use with an overhead projector. Specific types of transparency film are available for different types of printers. Many other specialty papers and other media are available for both ink jet and laser printers. Using your classroom printer and selected specialty output media, you can print T-shirt transfers, custom stickers, CD labels, magnets, glossy digital photos, and a variety of other unique printouts (Lever-Duffy, 2011).
The Electronic Whiteboard gives an educator the opportunity to use information from computer and use erasable markers to place emphasis, and explain important information. These boards have other uses such as a monitor, and without computer, connection it is used a regular blackboard. The challenge to this component offers no support for saving hand written information.
An input device includes any computer peripheral that you might use to enter data into the computer. A peripheral is any device that can be connect.ed to a computer. The keyboard and the mouse are the most often used types of input devices (Lever-Duffy & McDonald, 2011)
Key Boards and Mouse
Output devices are the pieces of hardware that move information (data that have been processed) out of the computer. The two primary output devices for most computer systems are the monitor and the printer. The monitor displays information in soft copy (electronic form), and the printer turns that information into hard copy (printed form) (Lever-Duffy & McDonald, 2011).
Tablet PCs offer teachers and students some unique opportunities. Teachers can download students’ word-processed essays and grade them via the tablet PC. The word-processed document is displayed on the tablet screen, and the teacher can add comments via the stylus. The graded document can be saved and returned to the student electronically for review. Connected to a classroom display device, the tablet PC can also be used for sharing digital images without the physical barrier of computer and monitor between teacher and class.
Data projector is a projection unit that combines an LCD display and a light source into a single, relatively lightweight box. As a result, data projectors are often referred to as LCD projectors. These units can typically project both images from a computer and video from a video source in a display that is large enough and bright enough to be seen across a classroom. For the brightest, clearest, and best results, these images should be displayed on a projection screen (Lever-Duffy & McDonald, 2011).
