What is virtualization technology?
Virtualization technology: simultaneously running two or more operating systems on one computer
100
TRUE or FALSE: ROM chips retain their contents even when the computer is powered down. The contents cannot be erased or changed by normal means.
TRUE: ROM chips retain their contents even when the computer is powered down. The contents cannot be erased or changed by normal means.
100
Which 2 devices are input devices? (1) digital camera (2) printer (3) biometric authentication device (4) projector
(1) digital camera (3) biometric authentication device

What is overclocking?
Overclocking is a technique used to make a processor work at a faster speed than its original specification.
100
What is IDE? How many pins are used?
(Integrated Drive Electronics) An early drive controller interface that connects computers and hard disk drives; Uses a 40-pin connector.
200
What type hardware upgrade would allow the processor in a gaming PC to have the optimal gaming performance?
Large amounts of faster RAM; Faster RAM will help the processor keep all of the data in sync because the data it needs to calculate can be retrieved when it's needed. The more RAM the computer has, the less often the computer needs to read from slower storage (a hard drive).
200
Where are basic instructions for booting the computer and loading the operating system stored?
ROM (Read Only Memory)
200
TRUE or FALSE: Redundant Array of Independent Disks (RAID) provides a way to store data across multiple hard disks for redundancy and data protection.
TRUE: Redundant Array of Independent Disks (RAID) provides a way to store data across multiple hard disks for redundancy and data protection.
200
Give 2 common examples of the type of adapter cards a PCI expansion slot is used for
PCI is used for: (1) Sound cards (2) Modems (3) Network cards (4) Storage device controllers
200
What is EIDE? How many pins are used?
(Enhanced Integrated Drive Electronics) The next generation of IDE interface that is faster than IDE. Uses a 40-pin connector.
300
Which 2 things would be the most important when building a workstation that runs multiple virtual machines? (1) water cooling (2) powerful video card (3) amount of RAM (4) number of CPU cores
(3) amount of RAM (4) number of CPU cores; Virtual computing requires more powerful hardware configurations because each installation needs its own resources and requires a lot of RAM and CPU processing power.
300
What is RAM?
RAM (Random Access Memory) is temporary storage for data and programs that are being accessed by the CPU.
300
Name 3 characteristics of RAID technology
(1) Striping: Splitting information and writing it across multiple physical disk drives (2) Mirroring: Duplication of data from one disk drive to another (3) Fault tolerance: the ability of a hard drive to keep working after there is a problem with one of the drives
300
TRUE or FALSE: Solid state drives (SSDs) have moving parts, which results in faster access to data, higher reliability, reduced power usage
FALSE: Solid state drives (SSDs) DO NOT have moving parts, which results in faster access to data, higher reliability, reduced power usage
300
What is SATA?
(Serial ATA) A replacement for the Parallel ATA interface; Uses a thin, small cable that helps make cable routing easier and offers better airflow in the computer.
400
A user playing a game on a gaming PC with an EIDE 5400 RPM hard drive is unhappy with the performance. Which hard drive upgrade would improve performance while providing more reliability and using less power? (1) 7200 RPM EIDE hard drive (2) 7200 RPM SATA hard drive (3) a SSD (Solid State Drive)
(4) a SSD (Solid State Drive) Games require a lot of storage so a fast hard drive is needed for the computer to load and run games quickly. A SSD performs faster than an EIDE or SATA drive.
400
What type of memory is mainly used as cache memory?
SRAM
400
Name 3 characteristics of RAID Level 0
(1) Data striping without redundancy (2) highest performance (3) NO fault tolerance (4) min. 2 disks
400
Name 3 types of optical drives
CD, DVD, Blu-Ray Disk (BD)
400
What does ATA stand for?
Advanced Technology Attachment (ATA)
500
Which is a possible use for virtual computing? (1) To allow users to browse the Internet without the risk of malware infecting the host software installation (2) To allow computer hardware to be tested (3) To allow computer hardware upgrades to be tested (4) To allow ROM firmware upgrades to be tested
(1) To allow users to browse the Internet without the risk of malware infecting the host software installation. ; By surfing the Internet in a virtual environment, a virus would only affect the one virtual environment. A separate virtualized work environment would not be affected by the virus.
500
TRUE or FALSE: DDR2 SDRAM is faster than DDR-SDRAM memory, accepts double the bandwidth of DDR SDRAM, and is the main standard for memory
TRUE: DDR2 SDRAM is faster than DDR-SDRAM memory, accepts double the bandwidth of DDR SDRAM, and is the main standard for memory.
500
What does the voltage selector switch on the power supply do and where is it located?
The voltage selector switch sets the input voltage to either: 110V/115V or 220V/230V; it's located on the back of the power supply.
500
Name 3 characteristics of RAID Level 10
(1) Data striping (2) increased performance (3) mirrored set of disks in a striped set (4) YES fault tolerance (5) high cost (6) min. 4 disks (must be an even # of disks)
500
What does SCSI stand for?
Small Computer System Interface (SCSI)
