97. What is a touch pad?

ANSWER:	A touch pad is a touch-sensitive pad across which a fingertip or thumb slides to move the on-screen pointer; tapping the touch pad (or one of its associated buttons) typically performs clicks and other mouse actions. Touch pads are the most common pointing device for notebook and netbook computers. They are used to point to and select objects, to scroll through documents or other content, and to perform gestures such as swiping and pinching. Because touch is so integrated into the newest operating systems (such as the most recent versions of Windows and OS X), there are also stand-alone touch pads available that can be used with computers that don’t have a touch screen. Touch pads are also built into some keyboards.

98. Describe the common features and uses of portable scanners.

ANSWER:	Portable scanners are designed to capture text and other data while on the go. Some are full-page portable scanners that can capture images of an entire document (such as a printed document or receipt); others are handheld scanners designed to capture text one line at a time. In either case, the scanner is typically powered by batteries, the scanned content is stored in the scanner, and the content is transferred to a computer (via a cable or a wireless connection) when needed. Some handheld scanners have OCR capabilities and some of these can also be used to translate scanned text from one language to another. One recent option is a scanner built into a mouse to enable users to switch between mouse actions and scanning as needed.

100. How do color and monochrome displays form colors?

ANSWER:	Display devices form images by lighting up the proper configurations of pixels (the smallest colorable areas on a display device—essentially tiny dots on a display screen). A variety of technologies can be used to light up the appropriate pixels needed to display a particular image, as discussed shortly. Display devices can be monochrome displays (in which each pixel can only be one of two colors, such as black or white) or color displays (in which each pixel can display a combination of three colors—red, green, and blue—in order to display a large range of colors). Most monitors and display devices today are color displays.
