Name 6 improvements of the ATX motherboard over the motherboard standards it replaced.
Built in double high io connector single main keyed internal power supply connector relocated cpu and memory relocated internal io connectors improved cooling lower cost to manufacturing
Because the PCI bus adds another layer to the bus configuration of the computer, it is often called a _______________________ bus.
mezzanine
Devices attached to the lowest-numbered interrupt have the highest priority
true
What is the purpose of DMA?
communications devices that must communicate at high speeds (Direct Memory Access)
What three differences exist between a microATX and an ATX board?

false, chipsets
When using a dual-color LED as a power indicator, a steady yellow LED power indicator indicates that the PC is ___
sleeping
What are the 3 official versions of the ATX standard?
ATX
microATX
flexATX
What are the advantages of the Hub Architecture?
faster
reduced PCI loading
reduced board wiring
What two advantages did the first chipset bring to the motherboard building when it was introduced in 1986?
Made building a pc cheaper
made designing a motherboard easier
The PCIe standard is essentially a serial bus

oct 2000
intel
FlexATX motherboards have the __________________physical standard dimensions of any of the ATX standard motherboard and might not even include expansion slots on the motherboard.
smallest
Which two obsolete form factors is the ATX form factor based upon?______________ AT [x] and ___________[y] Is it compatible with them(Yes/No)__________[z]?
Baby AT
LPX
Hub architecture chipsets have narrower busses that actually have higher data rates than North/South architecture chipsets
true
It is very easy to run out of I/O addresses (ports) on a computer
false
How do you tell, without opening the case, that an ATX motherboard is installed in a computer
Expansion boards plug directly into the motherboard
no riser card (perpendicular to motherboard)
For the ATX standard, match the port to the corresponding color
MIDI - gold
DVI - white
The PnP standard was later replaced by__________________
ACPI (Advanced Control and Power Interface
What two components control the speed and width of the processor bus on a motherboard?
processor snd chipset combo
The EISA bus was NOT designed to be backward compatible with the ISA bus
false
PCIe permits data to move both directions simultaneously ( full-duplex ) on each of its lanes
true
Match the terms associated with the North/South Bridge architecture with its definintion
North Bridge - connects the processor bus to AGP and PCI busses
South Bridge - bridges PCI and ISA busses
Super IO Chip - commonly used peripheral items in a single chip
Name 3 reasons why I/O bus speed must keep increasing
Faster CPUs
increasing software demands
greater multimedia requirements
