3.5 - Given a scenario, install and configure motherboards, CPUs, and add-on cards. Flashcards
Motherbaord form factors.
Physical size - case sizing.
Basic layout - room for small changes.
Power - standard connectors.
Airflow - increasingly important.
ATX
Advanced Technology Extended.
Power:
20 pin connector.
24 pin connector, additional 4/8 pin connector.
mATX
Micro Advanced Technology Extended.
Smaller than an ATX motherboard.
• Limited expansion slots.
Backward compatibility.
• Similar mounting points.
• Similar power.
ITX
Series of low-power motherboards.
• Developed by VIA Technologies in 2001.
Mini-ITX is screw-compatible with ATX and microATX.
• Fits almost any enclosure.
Small form factor uses.
• Single-purpose computing.
i.e., streaming media.
PCI
Peripheral Component Interconnect.
• Nobody ever calls it that.
A common expansion interface.
- 32-bit and 64-bit bus width.
- Parallel communication.
Throughput varies by bus version.
• 133 MB/s (32-bit at 33 MHz).
• 266 MB/s (32-bit at 66 MHz or 64-bit at 33 MHz).
• 533 MB/s (64-bit at 66 MHz).
PCIe
PCI Express.
• Replaced PCI, PCI-X, and
AGP (Accelerated Graphics Port).
Communicates serially:
• Unidirectional serial “lanes”
• Slower devices don’t slow down everyone
One, two, four, eight, sixteen, or thirty-two full-duplex lanes.
• x1, x2, x4, x8, x16, x32.
Different versions of PCIe.
• Improvement in speed with each iteration.
• Per-lane throughput in each direction.
- v1.x: 250 MB/s
- v2.x: 500 MB/s
- v3.0: ~ 1 GB/s
- v4.0: ~ 2 GB/s
- v5.0 (expected in 2019): ~ 4 GB/s
LGA
Land Grid Array.
Reverse the PGA - pins are on the motherboard.
- No pin to damage on the CPU.
- Easier to damage the motherboard.
PGA
Pin Grid Array.
CPU socket - ZIF
Zero Insertion Force.
SATA
IDE
Internal USB connector.
USB on the motherboard
• Integrated - part of the motherboard.
- On the back - keyboard, mouse.
- Internal case connection.
• Pins for case interfaces.
BIOS
UEFI BIOS
UEFI Advantages
Nonvolatile BIOS memory
