Digitizing tablets and tablet PCs are examples of ___________________ pads, a general class of input devices.

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

A(n) ____________________ is essentially an upside-down mechanical mouse.
