3.4 Expansion Cards Flashcards
What are the two main types of expansion cards in modern computers?
PCIe (PCI Express) and Mini PCIe.
What was the first 32-bit expansion card?
PCI (Peripheral Component Interconnect).
Why is PCI considered obsolete in modern computers?
It has a maximum data transfer rate of only 133 MB/s, which is too slow for modern needs.
What does PCI-X stand for?
PCI Extended.
What are the advantages of PCI-X over PCI?
PCI-X offers a 64-bit interface and faster bus speeds, up to 533 MHz, allowing higher data transfer rates.
What caused PCI-X to fall out of favor?
It slowed down when mixed with older PCI cards, limiting its effectiveness.
What does AGP stand for, and what was its purpose?
AGP stands for Accelerated Graphics Port, created to handle faster data transfers for graphics cards.
Why is AGP rarely used today?
AGP has been replaced by PCIe, which is faster and more versatile.
What does PCIe stand for?
PCI Express.
How do PCIe slots differ in size?
They come in x1, x4, x8, and x16 sizes, with x1 being smaller and slower and x16 used for high-speed devices like graphics cards.
What is the primary use of PCIe x1 slots?
For low-speed devices such as modems, network cards, wireless cards, and audio cards.
What is the primary use of PCIe x16 slots?
For high-speed devices, mainly graphics cards in gaming or 3D systems.
What is up-plugging in PCIe?
Using a smaller card (e.g., x1) in a larger slot (e.g., x16), which operates at the card’s speed.
What is down-plugging in PCIe?
Inserting a larger card (e.g., x16) into a smaller slot (e.g., x4), which requires support and results in slower performance.
What power does a standard PCIe slot provide?
25 watts.
