Question 6

Portable computers run on battery power, but data you are working on may be immediately affected by a power outage.

Accepted Answer

Portable computers such as laptops have batteries that provide a backup power source, allowing you to continue working for a period of time even during a power outage, thus preventing immediate data loss.

Question 7

Not all personal computers have an internal expansion bus that provides a variety of ways to connect peripheral devices.

Accepted Answer

All personal computers have an internal expansion bus, which is a system that allows various peripherals and expansion cards to connect to the motherboard and communicate with the CPU and other hardware components.

Question 8

A computer cannot function without peripheral devices.

Accepted Answer

A computer can function without peripheral devices for basic operations, as it primarily requires internal components like the CPU, memory, and storage to operate. Peripheral devices like a mouse, keyboard, or monitor enhance functionality but are not essential for all operations.

Question 9

A(n) APS is a device that not only provides surge protection, but also furnishes desktop computers and network devices with battery backup power during a power outage.

Accepted Answer

APS is likely a typo or confusion with UPS (Uninterruptible Power Supply), which is the correct device that provides both surge protection and battery backup power for computers and network devices during a power outage.

Question 16

LCD technology creates an image by bouncing light off of microscopically small mirrors arranged on a semiconductor chip.

Accepted Answer

LCD technology creates images by manipulating light using liquid crystals and a backlight, not by bouncing light off of microscopically small mirrors. The description given matches more closely with DLP (Digital Light Processing) technology.

Question 17

The most obvious computer malfunction is a failure to power up.

Accepted Answer

When a computer fails to power up, it's a clear and immediate indication that there is a significant problem, either with the power supply, the power button, or internal components, making it one of the most obvious malfunctions.
