input
A(n) ____________________ sensor scans for light or dark marks at specific locations on a page.
mark
A(n) ____________________ is a pointing device that's moved on a flat surface, such as a table, desk, or rubber pad.
mouse
A(n) ____________________ matrix display shares transistors among rows and columns of pixels.
passive
Speech ____________________ is where vocal sounds (phonemes) are stored in a computer system.
Synthesis
A stored set of numbers describing the content of all pixels in an image is called a(n) ____________________.
bitmap
The term "plotter" has faded in favor of the more descriptive term large-____________________ printer
format
________________ is the number of simultaneous sounds that can be generated.
Polyphony
_________________ is an IDL designed mainly for printed documents, although it can also be used to generate video display outputs
PostScript
A device that generates spoken messages based on text input is called a(n) ____________________ response unit.
audio
The ____________________ colors are cyan, magenta, and yellow.
CMY
________________ speech is a series of phonemes interspersed with periods of silence.
Continuous
________________ dithering is usually called half-toning
Grayscale
A(n) ___________________ matrix display uses one or more transistors for every pixel
_active
Display surfaces vary widely in size and ____________________.
composition
A(n) ____________________ converts incoming light energy into outgoing electrical energy
photosensor
Digital still cameras, video cameras, and Webcams use a 2D ____________________ array placed behind lenses to capture reflected and focused ambient light.
photosensor
To an observer, the quality of a printed or displayed image is related to the ____________________ size.
pixel
A(n) ____________________ display combines elements of CRT and LCD technology. Like LCDs, they're flat panel active matrix display devices
plasma
______________ are the most common unit for measuring font size.
point
Newer computers use ____________________, or multi-frequency, sound generation hardware with built-in amplification and high-quality speakers
polyphonic
Simultaneous read/write capability of VRAM is sometimes called dual-____________________.
porting
Each transfer of a full screen of data from the display generator to the monitor is called a(n) ____________________ cycle
refresh
When keys are pressed, a keyboard controller generates output called a(n) ____________________ code
scan
