C)trackpad
D)trackball

Accepted Answer

A trackball is the input device that resembles an upside-down mouse, as it has a similar shape but with the ball on top and the buttons below. The other input devices listed (touchpad, trackpoint, and trackpad) do not have a similar shape to an upside-down mouse.

Question 7

Before a computer can recognize handwriting,an input device must
A)be programmed.
B)optimize the information.
C)digitize the information.
D)show the information on a screen.

Accepted Answer

To recognize handwriting, an input device must first digitize the information. This means converting the handwritten text into digital data that can be processed and recognized by the computer. Programming and optimization may be necessary for the recognition software, but these are secondary steps that come after digitization. Displaying the information on a screen is also not necessary for handwriting recognition, although it may be useful for visual feedback.

Question 8

A standardized test that you may have taken in school could have been scored by a(n)________.
A)optical mark reader
B)bar code reader
C)magnetic ink character reader
D)scanner

Accepted Answer

Optical mark readers are often used to score standardized tests. The machines can quickly read and analyze data from answer sheets that have been marked using a pencil or pen. Bar code readers and magnetic ink character readers are typically used for other purposes, such as tracking inventory or processing financial transactions. While scanners can be used to capture images of documents, they may not have the specialized software needed to score standardized tests.

Question 9

A key on your keyboard can be used in combination with another key to modify meanings of keystrokes. For example,holding the Shift key while pressing the "S" key types a capital S,while Ctrl+S tell a Windows application to
A)search the current document.

Question 14

A touchpad responds to
A)light.
B)pressure.
C)clicking.
D)the sense of heat from fingertips.

Accepted Answer

A touchpad responds to pressure, which is generated by the user's fingers, rather than light, clicking or the sense of heat from fingertips. When a user puts pressure on the touchpad's surface, the touchpad senses this pressure and translates it into an action on the device, such as moving a cursor, scrolling or clicking.
