What best describes a disadvantage of notebook systems?

• They require AC power.

• The battery is difficult to replace.

• Productivity apps are difficult to use.

• They are more expensive

Answer explanation

Notebook systems are usually more expensive than comparable desktop systems.

Difficulty replacing the battery and using productivity apps are disadvantages of mobile devices.

Requiring AC power to operate is a disadvantage of desktop computers.

Mr. Morelock needs to take his ______ for slide show presentations to multiple classrooms at Farragut High School. The answer is an example of a hardware.

Answer explanation

A laptop would be Abby's best option because laptops are mobile and capable of running productivity software such as the presentation software she needs.

A desktop computer is not mobile and so would not be a good choice.

A gaming console is unable to use productivity software.

A server is not mobile and is not designed to run productivity software.

Of the following pieces of hardware, which is most easily repaired?

• Mr. Morelock's desktop computer

• Shaylee's Macbook

• Trent's X Box

• Sophia's Samsung Galaxy

• Chase's iPhone

Answer explanation

A desktop computer is the easiest device to repair. Desktops are generally designed to be easier to open, and so they are easier to repair or upgrade when needed.

Smartphones, gaming consoles, and laptops can very difficult to repair as they are not designed to be easily opened.

Mr. Morelock needs a device for his new job as a graphic designer. The software he is using will be upgraded regularly and he will need to use large, dual screens. What should he buy?

• Nintendo 64

• Desktop Computer

• A brand new Chromebook (the same model that student's use at Farragut High School)

• An iPhone 15 Max Pro

What best represents an example of computer hardware?

• A Website

• A Microchip

• Canvas Assignment

• Google Form Survey

Devices that have cameras generally built into their hardware are: (select 2)

• Laptops

Of the following choices, which converts AC to DC?

• Capacitor

• Power Supply

• Surge protector

• Voltage regulator

Answer explanation

A computer's power supply converts alternating current (AC) from the wall outlet to direct current (DC) used by the computer's internal components.

A voltage regulator is an electronic device that supplies the appropriate voltage to a processor. It does not convert the power input from one form to another; it only ensures that the voltage remains at the appropriate level for the device. A surge protector protects a system from power spikes. A UPS (uninterruptable power supply) provides backup AC power using a reserve battery.

Which of the following voltages from an ESD discharge would be the minimum to short a computer's hardware components?

• 20 volts

• 37 vols

• 100 volts

• 10 volts

Answer explanation

An ESD discharge as small as 100 volts can damage a computer's components.
