OUTPUT DEVICES

 

Monitor

*The monitor is your view into the computer. They come in all shapes and sizes, but the main ones being sold today are LCD (Liquid Crystal Display) monitors. There's quite a big difference between LCD and CRT (Cathode Ray Tube) monitors and CRT monitors are slowly being phased out and replaced by LCD's. LCD monitors are much lighter and thinner, they take up less space, and provide a crisper more focused image.

 Speaker

*Independent speakers when attached to the computers can really make listening music or playing multimedia games a really good experience. Different types of speakers include the standard 2-speakers, 2.1 speakers with 1 sub-woofer, 4.1 speakers, and 5.1 speakers.

Printer

 

*A computer printer is another type of output device. Many modern printers have the ability to interface with different media types such as memory sticks, memory cards, and cameras. 

Projector

*A video projector is a device that receives a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings.

Scanner

*A device that optically scans images, printed text, handwriting, or an object, and converts it to a digital   image. Common examples found in offices are variations of the desktop (or flatbed) scanner where the document is placed on a glass window for scanning.
