Q

Multi-Core processor

Study These Flashcards
A

Single CPU with multiple processors inside

22
Q

Virtualization

Study These Flashcards
A

Being able to emulate hardware that doesnt really exist.
Lets a computer pretend its running multiple other computers inside itself
VT (Intel) and AMD-V provide processor extensions to support virtualization

23
Q

Extended Page Table (EPT)

Study These Flashcards
A

Intel second level of virtualization support

24
Q

Rapid Virtualization Indexing (RVI)

Study These Flashcards
A

AMD second level of virtualization support

25
Mainboard power
24 pin connector to power motherboard
26
CPU power
8 pin power socket used to power CPU
27
USB header port
used to connect USB ports to Motherboard
28
SATA ports
Used to connect SATA devices to motherboard
29
Audio Header port
9 pin connector to connect audio
30
7 Step Process for installing a motherboard
1. Review documentation 2. position the motherboard to line up with rear port cluster 3. Install standoffs 4. install the CPU and memory modules first 5. verify standoff alignments 6. secure standoffs using proper screw types 7. install the power supply, disk drives, add on cards, and others
31
PCI
32-bit expansion card used for network and audio cards maximum bus speed of 33 MHz or 133 MBps
32
PCI-X
64-bit expansion card 133 MHz
33
PCI-X 2.0
266 MHz
34

old port used only for video graphics cards came in 1x, 2x, 4x, 8x
35
Peripheral Component Interconnect Express (PCIe)
Connects to the bus to get data to and from the motherboard for external devices replaces PCI, PCI-X, AGP The x denotes how long the bus is PCIe x1: used for modems, network, wireless, I/O, and audio PCIe x4: less common PCIe x8: less common PCIe x16: used for graphics cards
36
PCIe power
PCIe by default provides 25 watts of power PCIe x16 card slots provides up to 75 watts of power
37
Up-plugging
