3.4 - Motherboard Expansion Slots Flashcards
What components are typically found on a motherboard?
CPU, memory, storage, and expansion slots.
What is required for different components on a motherboard to communicate with each other?
A series of communication paths called a bus.
What is PCI and when was it introduced?
Peripheral Component Interconnect, introduced in 1994.
What are the two bus sizes for PCI?
32-bit and 64-bit.
How does a 64-bit PCI bus compare to a 32-bit PCI bus?
The 64-bit bus is twice as large as the 32-bit bus and has parallel communication.
What are the voltage capabilities of a 32-bit PCI card?
3.3 volts and 5 volts.
What feature distinguishes a 64-bit PCI expansion card?
Additional contacts for 64-bit width and support for 3.3 and 5 volts.
What is the purpose of keys on PCI cards?
To ensure that only the correct card is installed onto the motherboard.
What is PCIe and how does it differ from PCI?
PCIe (PCI Express) replaces PCI, using a serial connection instead of parallel.
What are PCIe lanes and their purpose?
Communication paths that can be added to support more data transfer, referred to as x1, x2, x4, x8, x16, or x32.
How does a PCIe 1x connection work?
It has one communication path in each direction.
What does a PCIe x4 lane configuration look like?
It has four communication paths between devices.
How can you distinguish between PCI and PCIe slots on a motherboard?
PCI slots are usually older and parallel, while PCIe slots are newer with different numbers of lanes and contacts.
How should you install a PCIe adapter card?
Align the card with the slot, gently push it down, and lock it into place with the screw connection on the case.
How do PCIe adapter cards compare to PCI cards?
PCIe cards have different slots and contact configurations and may include a hook to lock the card in place.
