What are the four most common catagory of expansion cards?
Video
Multimedia
Communications
Input/Output
What is important to remember when installing an expansion card, no matter what type the card is?
That it matches the bus on the motherboard it is going to be installed in. E.G. PCI Network cards must go in PCI slot.
Video adapter card (or graphics cards) can come in two types, what are they?
Onboard cards, which are built in to the motherbaird, and add on cards that will typically go into the PCIe slot.
What the advantages and disadvantages of having an onboard video card?
Having a video card built into the motherboard frees up an expansion slot. If the video card fails it means getting another motherboard or buying an add on card.
What is a TV Tuner / Video caprure card used for?
These allow you to connect a broadcast signal , such a cable TV, to your computer.
What is a difference between a network card and modem card?
Modem cards have have smaller 4-pin RJ-11 connectors where as network cards have larger 8-pin RJ-45 connectors.
Name some examples of input/output cards
USB cards
Storage Cards, such as eSATA
Thunderbolt cards
What is the most common way to configure a newly installed expansion card?
The plug and play utility
If the card isn’t recognised or isn’t functionaing as expected where might be best to look?
The BIOS for configuration settings

What is the transfer rate of BD-ROM?
standard 1X is 4.5 MBps
What does RAID stand for?
Redundant Array of Indepedent Disks.
What is RAID 0
Disk Striping. Increasing data access. No faut tolerance. Minimuim two drives.
What is RAID 1
Disk mirroring. Writing data to two drives simultaneously. Does not help with speed but if one drives fails the data is written to the other. Has fault tolerance.
What is RAID 5?
Striping with parity. Combination of the benefits of RAID 0 & 1 to create a redundant striped volume set. Minimum of 3 drives.
What is RAID 10?
Mirroring with striping. Also known as RAID 1+0 adds fault tolerance.
What are some of examples of flash drives?
MMD - MultiMediaCard
SD - Secure Digital
USB Flash Drives
What kind of power connectors would a legacy AT motherboard require?
AT system connectors
Also know as a Molex connector, what connector was used for hard drives, optical drives and other internal peripherals?
Standard Peripheral Power Connector
