keyboard

an *input device* containing *numerous keys* that can be used to input letters, numbers, and other symbols

pointing device

an *input device* that moves an *on-screen point*, such as an arrow, to allow the user to select objects on the screen such as mouse, pen/stylus

scanner

an *input device* that reads printed text and graphics and transfers them to a computer in digital form

flatbed scanner

an input device that *scans flat objects* one at a time

digital cameras

an input device that *takes pictures* and records them as digital images

stylus

an input device that is used to write electronically on the display screen; also called a digital pen, electronic pen, or pen

digital still cameras

an input device; images are *immediately available* for viewing or printing, instead of having to have the film developed first

pixel

the *smallest colorable area* in an electronic image, such as a scanned image, a digital photograph, or an image displayed on a display screen

optical character recognition (OCR)

the ability of a computer to *recognize scanned text characters* and convert them to electronic form as text, not images

handwriting recognition

the ability of a device to *identify* handwritten characters written text can be converted to editable typed text with this ability

screen resolution

this is *determined* by the number of pixels used on a display screen this affects the *amount of information that can be displayed* on the screen at one time

CRT monitor

this used to be the norm for desktop computers use the same *cathode-ray tube* technology used in conventional televisions in which an electron gun sealed inside a large glass tube projects an electronic beam at a screen coated with read, green, and blue phosphor dots the beam lights up the appropriate colors in each pixel to display the necessary image as a result, *they are large, bulky and heavy*
