Video and Expansion Cards Questions
and Answers
Peripheral Component Interconnect - answer A connection slot for a 32-bit computer
bus. PCI was developed to replace the obsolete Industry Standard Architecture (ISA)
and Video Electronic Standards Association (VESA) bus standards.
-Is processor independent, meaning the CPU and PCI bus can process concurrently.
-Supports plug-and-play, meaning installed devices are detected and configured
automatically.
-Is commonly used by devices such as older or less demanding sound cards, modems,
network cards, and storage device controllers.
-Can run at 33 MHz and transfer data at 133 MBps or run at 66 MHz and transfer data
at 266 MBps.
PCI Extended (PCI-X) - answer A PCI design that overcomes PCI bandwidth
limitations.
PCI Express - answer The connector that replaced PCI, PCI-X and AGP
(accelerated graphics port). Instead of a shared bus, each PCIe slot links to a switch
that prioritizes and routes data through a point-to-point dedicated connection. PCIe
provides a serial, full-duplex method of transmission. Typically used for modern and
higher-performance network cards, USB cards, and sound cards. Data rates depend on
the protocol version and number of transmission lines.
*PCIe cards are cross-size compatible when the slot size is the same or larger than the
card size. For example, a PCIe x1 card can be installed in a PCIe x16 slot, but a PCIe
x16 card cannot be installed in a PCIe x1 slot.
Mini PCI - answer A subset of the PCI interface, but with a small form factor.
Legacy bus - answer Buses that have been replaced by newer types are considered
legacy buses. Legacy buses are rarely used and include the following:
-AGP is a dedicated bus type used by dedicated video cards.
-Audio/modem riser (AMR) is a riser card that attaches to the motherboard and allows
additional cards (called daughter cards) to be installed.
-Communications network riser (CNR) is a riser card slot that allows for installing
network, sound, or modem functions.
Multi-GPU - answer The ability to link video cards together. This allows you to share
the graphic processing load between the two GPUs.
DirectX/(Open Graphics Library (openGL) - answer A collection of application
program interfaces (APIs) that improves graphic, animation, and multimedia creations.
, High-Bandwidth Digital Content Protection - answer A digital copy form designed to
protect digital media from piracy.
What advantage does a Peripheral Component Interconnect Express (PCIe) bus have
over a PCI bus? - answer Faster Data Transfer. Increased Scalability (supports
multiple lanes, each lane can transmit data independently providing more bandwidth for
devices connected to the bus, allows for the use of multiple PCIe devices
simultaneously, accommodating the increasing bandwidth requirements of modern
peripherals). Lower Latency. Hot-Plug Capability. Improved Performance for Graphics
and High- Bandwidth Devices. Enhanced Protocol Features (incorporates advanced
error checking, land deactivation, and power management capabilities enhancing
system reliability, power efficiency and performance optimization).
Which type of devices typically use mini PCI cards? - answer Laptops and other
small form factor devices.
Which bus type is commonly used by graphics cards? - answer a high-speed serial
connection (like a single file line, where each bit follows one after another in a
sequential manner; analogous to people walking in a line, with one person following
another)
What type of slot can a PCIe x1 expansion card be placed in? - answer the PCIe x1
expansion slot
used by network cards, USB cards, dedicated sound cards
(PCIe x16 primarily used by dedicated video cards)
How does the video card affect the quality of the image on the monitor? - answer
Both the video card and the external display determine the quality of images and
animation. When selecting a video card, consider resolution (number of pixels) and
refresh rate (number of times in one second that the GPU draws a frame, measured in
hertz).
Which type of Digital Video Interface (DVI) connector sends digital signals only? -
answer DVI-D (Digital Visual Interface-Digital).
How does the graphics processing unit (GPU) increase the video performance? -
answer The GPU handles all video rendering tasks. GPUs are much more efficient at
processing graphic data than a traditional CPU.
What are the differences between integrated graphics and dedicated video cards? -
answer Integrated video cards:Integrate the graphics processing unit (GPU) with
another hardware component (e.g., the central processing unit (CPU) or
motherboard).Share system memory for graphic processing.Are less expensive than
dedicated video cards, but are also less powerful.Are installed in most pre-built PCs and
found in most laptops. Integrated cards are also used in servers.
