Question 1

Case 4-1 Sierra has owned her computer for almost two years and decides to upgrade it so that she can increase her output and production. Which purchase would provide Sierra the best value for increasing overall computer performance?

Accepted Answer

Additional computer memory would provide Sierra with the best value for increasing overall computer performance. It would improve the speed and efficiency of her computer, allowing her to run more programs and processes simultaneously. A cable management kit would only help tidy up her workstation, a touchpad is a peripheral device that doesn't directly affect computer performance, and Corona wires are not a relevant purchase for upgrading a computer.

Data stored in RAM is temporary because it is only stored as long as the computer is turned on. As soon as the computer is shut down or the power is lost, the data in RAM is lost, so it is not considered permanent storage.

Question 5

Disk ____ is one of the more time-consuming elements in a computer's performance.

Accepted Answer

Seek time refers to the amount of time it takes for a hard drive to locate and access a specific piece of data. This can be a slower process and can affect the overall performance of the computer. Defragmentation, cleanup, and deletion can all help improve disk performance but they do not directly address the seek time issue.

The Recycle Bin is used to temporarily store files that have been deleted, the defragmentation utility is used to optimize the performance of the hard drive, and there is no self-cleaning mode in Microsoft Windows.

A mouse with a ball is a mechanical mouse, as it uses a rolling ball to detect movement and translate it into cursor movement on a computer screen. A wireless mouse uses Bluetooth or other wireless technology to communicate with the computer. An ergonomic mouse is designed to reduce strain and discomfort for the user, often featuring a sculpted shape intended to fit the hand comfortably. A laser mouse uses a laser sensor to detect movement and tends to be more precise and responsive than a mechanical mouse, but is also more expensive.

Deleting cookies can improve computer performance and security. The Recycle Bin contains deleted files, fragmented files refer to files that are broken into pieces and scattered across different parts of the hard drive, and system properties refer to settings and information about the computer's hardware and software.

Question 15

Question 17

Case 4-1 Sierra has owned her computer for almost two years and decides to upgrade it so that she can increase her output and production. If Sierra wants to move around as necessary and not be bound to her desk, she should purchase ____.

Question 20

Which of the following should be considered when selecting a keyboard?

Accepted Answer

All of the above factors should be considered when selecting a keyboard. Design can be important for aesthetics or specific features like backlighting. Performance affects how quickly and accurately the keyboard registers keystrokes. Comfort is important for avoiding strain or pain during extended typing sessions. All these factors should be weighed together for the best keyboard selection.
