9. ### Which unit of measurement is used to indicate the hard drive speed?

• revolutions per minute
• gigabytes
• pages per minute
• clusters per minute
 Explanation: Revolutions per minute (RPM) is the speed at which the spindle in a hard drive spins. The faster the spindle spins, the faster the data can be retrieved from the platters.
10. ### Which type of interface was originally developed for high-definition televisions and is also popular to use with computers to connect audio and video devices?

• FireWire
• DVI
• HDMI
• USB
• VGA
 Explanation: High definition multimedia interface, or HDMI, was originally a television standard. However, because it has many digital features, it is also a popular interface to connect audio and video devices to computers.
11. ### Which two devices are considered input devices? (Choose two.)

• biometric authentication device
• printer
• digital camera
• projector
• speakers
 Explanation: Biometric authentication devices and digital cameras are considered input devices. Speakers, projectors, and printers are all considered as output devices.
12. ### What is indicated by the contrast ratio of a monitor?

• the difference in the intensity of light between the brightest white and darkest black that can be displayed
• how often the picture image is refreshed
• the total number of pixels that make up the picture
• the ratio of the horizontal and vertical viewing areas of the monitor
 Explanation: Contrast ratio is one of many factors that is used to describe the resolution of a monitor. Contrast ratio is a measure of the difference in intensity between white and black areas of the picture. A higher contrast ratio means the monitor can produce pictures with brighter whites and darker blacks.
13. ### What type of connector can be used to connect an internal hard drive to the motherboard?

• USB
• SATA
• eSATA
• Thunderbolt
 Explanation: A SATA interface uses a 7-pin data connector and connects and internal SATA hard drive to the motherboard.
14. ### Which two factors must be considered when replacing old RAM modules in a PC? (Choose two.)

• The new RAM must be compatible with BIOS or UEFI.
• The new RAM must be compatible with the motherboard.
• The speed of the new RAM must be supported by the chipset.
• The power supply must provide the voltage that is requred by the new RAM.
• The new RAM must match the old RAM in terms of capacity and speed.
 Explanation: When the RAM on a motherboard is being replaced or upgraded, the new RAM module must be compatible with the current motherboard. In addition, the speed of the new RAM must be supported by the chipset.
15. ### Which term is used to define the wires on a motherboard that move data from one part of a computer to another?

• bus
• I/O card
• bridge
• chipset
 Explanation: Data is moved on the motherboard over a collection of wires known as a bus. Busses serves two purposes: (1) to carry data between computer components and (2) to carry the memory address locations of where the data is read and written by the CPU.
16. ### When a new PC is being built, which component has the most influence when selecting the case and power supply?

• video card
• sound card
• RAM module
• motherboard
• hard disk type
 Explanation: The choice of motherboard determines the type of case and power supply. The form factor of a motherboard must match the type of case and power supply. RAM modules, video cards, and sound cards are installed on the motherboard. They must be compatible with the motherboard. A hard disk is attached to the case, but the dimensions of the drive bays are standardized.
17. ### What is the function of the power supply?

• to convert AC power into a lower voltage DC power
• to convert AC power into a higher voltage DC power
• to convert DC power into a lower voltage AC power
• to convert DC power into a higher voltage AC power
 Explanation: The power supply converts alternating current (AC) power coming from a wall outlet into direct current (DC) power, which is of lower voltage. DC power is required for all the components inside the computer.
18. ### Which two considerations would be of the greatest importance when building a workstation that will run multiple virtual machines? (Choose two.)

• amount of RAM
• number of CPU cores
• water cooling
• powerful video card
• high-end sound card
 Explanation: Virtual computing requires more powerful hardware configurations because each installation needs its own resources and thus requires a lot of RAM and CPU processing power.

• a high speed wireless adapter
• multiple monitors
22. ### Which memory technology allows two memory modules to be accessed at the same time?

• dual channel
• double-sided
• SRAM
• ECC
 Explanation: Dual channel RAM has two channels so that two memory modules can be accessed at the same time. Double-side memory modules have RAM on both sides of the module. Static RAM (SRAM) is memory that does not need refreshing, thus providing faster access to data. Error Correction Code (ECC) is a method of error checking.​
23. ### Which security feature in modern CPUs protects memory areas that contain part of the operating system from malware attacks?
