Q41.
What is a 'double-click' in terms of mouse operations?

a.

Pressing the mouse button once.

b.

Pressing the mouse button twice in rapid succession.

c.

Pressing two mouse buttons at the same time.

d.

Dragging the mouse while holding the button down.

Discuss
Answer: (b).Pressing the mouse button twice in rapid succession. Explanation:A 'double-click' is a mouse operation where the button is pressed twice in rapid succession. This operation is often used to open files or applications on a computer.
Q42.
Who developed the mouse and when?

a.

Bill Gates in 1981.

b.

Douglas C. Engelbart in 1964.

c.

Steve Jobs in 1976.

d.

Alan Turing in 1945.

Discuss
Answer: (b).Douglas C. Engelbart in 1964. Explanation:The computer mouse was developed around 1964 by Douglas C. Engelbart. The first prototype of the mouse used two wheels to transmit x–y coordinates to the computer.
Q43.
How is the mouse an indirect input device?

a.

Because it requires a transformation to map from the horizontal nature of the desktop to the vertical alignment of the screen.

b.

Because it requires the use of a keyboard to function properly.

c.

Because it needs a direct physical connection with the computer.

d.

Because it can only be used with certain types of computers.

Discuss
Answer: (a).Because it requires a transformation to map from the horizontal nature of the desktop to the vertical alignment of the screen. Explanation:A mouse is an indirect input device because it requires a transformation to map the movement of the mouse on a horizontal surface (like a desk) to the vertical alignment of the cursor on the screen.
Q44.
What is an advantage of the mouse as an input device?

a.

It provides absolute coordinates of movement.

b.

It requires extensive training to use effectively.

c.

The cursor can be easily manipulated without obscuring the display.

d.

It requires a lot of physical space on the desk.

Discuss
Answer: (c).The cursor can be easily manipulated without obscuring the display. Explanation:A major advantage of the mouse is that it allows the cursor to be small and easy to manipulate, without obscuring the display. This makes it more efficient and user-friendly for interacting with on-screen elements.
Q45.
How did the first mouse prototype differ from modern versions?

a.

The first mouse prototype required a direct physical connection with the computer

b.

The first mouse prototype could obtain pure vertical or horizontal motion by tilting it so that only one wheel was in contact with the desk

c.

The first mouse prototype was digital, not analog

d.

The first mouse prototype was made entirely of plastic

Discuss
Answer: (b).The first mouse prototype could obtain pure vertical or horizontal motion by tilting it so that only one wheel was in contact with the desk Explanation:The first mouse prototype, developed by Douglas C. Engelbart in 1964, used two wheels to transmit x–y coordinates to the computer. This design offered a few advantages over today’s versions, one being the ability to achieve pure vertical or horizontal motion by tilting the mouse so that only one wheel was in contact with the desk.
Q46.
What is a footmouse?

a.

A foot-operated device that moves the cursor by foot pressure on one side or the other of a pad.

b.

A device used to control musical instruments.

c.

A type of mouse that is controlled by foot gestures.

d.

A large type of mouse used for graphic design.

Discuss
Answer: (a).A foot-operated device that moves the cursor by foot pressure on one side or the other of a pad. Explanation:The footmouse is a foot-operated device that functions similar to an isometric joystick than a mouse. The cursor is moved by foot pressure applied on either side of a pad. This device is not common but allows users to dedicate their hands to the keyboard.
Q47.
What is a touchpad?

a.

A device that is touch-sensitive and is operated by stroking a finger over its surface.

b.

A device that translates handwriting directly into text.

c.

A device that controls the movement of a computer's processor.

d.

A device that allows you to touch the screen to move the cursor.

Discuss
Answer: (a).A device that is touch-sensitive and is operated by stroking a finger over its surface. Explanation:A touchpad is a touch-sensitive device that is usually around 2–3 inches (50–75 mm) square. It is operated by stroking a finger over its surface, similar to using a simulated trackball. It is extensively used in laptop computers and can be obtained separately to replace the mouse on the desktop.
Q48.
How does the acceleration setting improve the user experience with a touchpad?

a.

It makes the touchpad bigger, so you have to move your finger less.

b.

It decreases the sensitivity of the touchpad, requiring more effort to move the cursor.

c.

It varies the ratio of pad distance to screen distance with the speed of movement.

d.

It makes the touchpad less sensitive to accidental touches.

Discuss
Answer: (c).It varies the ratio of pad distance to screen distance with the speed of movement. Explanation:The acceleration setting improves the user experience with a touchpad by varying the ratio of pad distance to screen distance with the speed of movement. If the finger moves slowly over the pad, the pad movements map to small distances on the screen. If the finger is moving quickly, the same distance on the touchpad moves the cursor a long distance. This setting is used to enhance the 'feel' of the device and can also be found in other indirect positioning devices like the mouse.
Q49.
What hinders the wide adoption of foot-operated controls like the footmouse in computing?

a.

They are too complicated to use.

b.

They can be operated accidentally and may be awkward to use, especially with laptops.

c.

They are too expensive to produce.

d.

They are not as precise as hand-operated devices.

Discuss
Answer: (b).They can be operated accidentally and may be awkward to use, especially with laptops. Explanation:While foot-operated controls like the footmouse are not intrinsically a bad idea (and are, in fact, commonly used in musical instruments and industrial controls), two main issues limit their widespread use in computer interfaces. One is the practicality of having such controls in the work environment. Pedals under a desk could be accidentally operated and using such devices with laptops would be inconvenient.
Q50.
What is a trackball?

a.

A trackball is a touch-sensitive device that is operated by stroking a finger over its surface.

b.

A trackball is a device that translates handwriting directly into text.

c.

A trackball is an upside-down mouse where a weighted ball faces upwards and is rotated inside a static housing.

d.

A trackball is a foot-operated device that moves the cursor by foot pressure on one side or the other of a pad.

Discuss
Answer: (c).A trackball is an upside-down mouse where a weighted ball faces upwards and is rotated inside a static housing. Explanation:A trackball is essentially an inverted mouse. It consists of a weighted ball that faces upwards and is rotated within a static housing. The motion is detected in the same manner as for a mechanical mouse, and the relative motion of the ball moves the cursor on the screen.
