Your friend Joe wants to add another hard drive to his computer. What should he check to make sure that his system will support it?
A. PSU
B. Expansion Slots
C. CPU
D. RAM
Joe needs to make sure his power supply unit (PSU) has a free connector, as well as enough power to supply the drive.
Hard disk drives do not use expansion slots.
Which of the following devices is most likely to have a joystick port on it?
A. Video Card
B. Sound card
C. Network card

Older sound cards had 15-pin joystick ports on them, as well as audio input and output jacks.
You want to upgrade your computer to give it a faster boot time and more space for your files. What should you purchase?
A. RAM
B. HDD
C. SSD
D. CPU
A solid-state drive (SSD) will provide faster bootup times than a conventional hard disk drive (HDD)
If your computer runs low on RAM, what will it use instead?
Virtual memory is hard drive space used as extra memory if your system runs low on physical memory.
Virtual memory is slower than physical memory.
Which of the following are hard drive connector types? (Choose two)
A. PATA
B. SATA
C. PCIe
D. AGP
Parallel ATA (PATA) and Serial ATA (SATA) are two hard drive connection types.
PCIe and GP are expansion slots
When you turn on your computer, it tells you that it does not hav the time and date set and asks you to enter setup. What likely needs to be replaced?
CMOS battery
The BIOS stores configuration information such as time and date, but it is powered by the CMOS battery when the system is off.

Small outline dual inline memory module (SODIMM) are made for laptops
Which device is connected to the motherboard with a 24-pin block connector?
Power Supply Unit
Which of the following is faster than RAM?
A. Cache B. HDD C. SSD D. BD-ROM E. none of the above
Cache
Cache is temporary memory that is closer to the processor than RAM, and it is therefore slightly quicker. It usually comes in smaller quantities.
Which of the following processor types is most likely to be found in a smartphone?
A. 32-bit
B. GPU
C. Intel
D. ARM
ARM
Small devices, such as smartphones and tablets, are most likely using ARM processors. They could be 32-bit or 64-bit.
A GPU is for video processing and Intel does not currently produce ARM chips.
You installed more memory in your computer, but it’s not recognized. Your friend suggests that you upgrade your BIOS. What’s the best way to do this?
If you want to upgrade a BIOS, the best way to do so is to flash it.
