INTE 1100 Ch01 Study Guide Flashcards
A user playing a game on a gaming PC with a standard EIDE 5400 RPM hard drive finds the performance unsatisfactory. Which hard drive upgrade would improve performance while providing more reliability and using less power?
a 7200 RPM EIDE hard drive,
a 7200 RPM SATA hard drive,
a 10,000 RPM SATA hard drive,
an SSD
SSD
Games require a lot of storage. In order for the computer to load and run games quickly, a fast hard drive will need to be installed. To obtain best performance an SSD (Solid-State Drive) will perform faster than an EIDE drive or a SATA drive
Which hardware upgrade would allow the processor in a gaming PC to provide the optimal gaming performance?
large amounts of fast RAM
liquid cooling
a fast EIDE drive
a high capacity external hard drive
large amounts of fast RAM
Faster RAM will help the processor to keep all of the data in sync because the data that it needs to calculate can be retrieved when it is needed. The more RAM that the computer has, the less often the computer needs to read from slower storage such as hard drives or SSDs.
Which two storage devices use a magnetic medium for storing data? (Choose two.) tape drive solid state drive hard disk drive blue-ray disk drive compact disk drive
Hard disk drive
A hard drive, or hard disk drive, is a magnetic storage device that is installed inside the computer. The hard drive is used as permanent storage for data.
A tape drive is a magnetic storage that is most often used for backup or archive data. Magnetic tapes are used to store data via a magnetic read/write head

Which component controls the communications and interactions between the CPU and other components on the motherboard? RAM BIOS CMOS chipset
Chipset
The chipset controls communication between the CPU and other computer components.
Which two pieces of information are needed before selecting a power supply? (Choose two.)
the type of CPU the form factor of the case the installed operating system the total wattage of all components the voltage requirements of peripheral devices supply, and other internal components.
the type of CPU
the form factor of the case
the total wattage of all componentsthe
Which memory module has a front side bus speed of 200 MHz?
DDR-333
DDR-400
DDR3-667
PC100 SDRAM
DDR-400
The bus speed of DDR-400, also known as PC-3200, is 200 MHz.
What are two factors that must be considered when choosing a computer case? (Choose two.)
the size of the monitor
the vendor that manufactured the motherboard
the number of internal drive locations
the size of the motherboard and the power supply
the number of LED indicators at the front of the case
the number of internal drive locations
the size of the motherboard and the power supply
The size and shape of the computer case is usually determined by the motherboard form factor, power supply, number of external ports, and the number of internal drive bays.
Which three devices are considered output devices? (Choose three.)
fingerprint scanner headphones keyboard monitor mouse printer
Headphones, monitors, printers,
speakers,scanners, fax machines, and projectors are all considered output devices. Fingerprint scanners, keyboards, and mice are all considered input devices.

Which unit of measurement is used to indicate the hard drive speed?
revolutions per minute
Gigabytes
pages per minute
clusters per minute
revolutions per minute
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.
Which component controls the communications and interactions between the CPU and other components on the motherboard?
RAM
BIOS
CMOS
Chipset
Chipset
The chipset controls communication between the CPU and other computer components.

the type of CPU
the form factor of the case
the installed operating system
the total wattage of all components
the voltage requirements of peripheral devices
the form factor of the case
The total wattage of all components
When building a computer, select a power supply with sufficient wattage to power all the components. Each component inside the computer uses a certain amount of power. Obtain the wattage information for the components from the manufacturer documentation. When deciding on a power supply, make sure to choose a power supply that has more than enough power for the current components.
The shape of the computer case is usually determined by the motherboard, power supply, and other internal components.

What type of connector can be used to connect an eSATA interface to an external SATA drive? 5-pin connector 7-pin connector 9-pin connector 15-pin connector
7-Pin connector
A SATA interface uses a 7-pin data connector and can be up to two meters (6.56 ft.) in length.
Where can the input voltage selection be changed from 110 volts to 220 volts on a computer system?
in the BIOS
on the motherboard
on the back of the power supply
in the operating system control panel
On the back of the power supply
On the back of many power supplies is a small switch called the voltage selector switch. This switch sets the input voltage to the power supply to either 110V / 115V or 220V / 230V.
