Video Memory is used to store image data for a
computer display in order to speed the processing and
display of video and graphics images.
1) Processes images and displays it on the monitor
2) Takes some of the workload for the CPU
3) Allows your computer to run smoothly while multi-tasking
The more the better
Every PC has at least 250MB (not very much)
You can add/remove
Video Memory is also provided
on a Video Graphics Card
Key points:
1) Intermediate storage area between the microprocessor and the display
2) There are different/variations of video memory
3) Helps speed up a computer’s performance
4) Every computer has some
5) The more the better
A video card (graphics card) combines video processing and storage onto an
expansion card, or integrated onto the motherboard to manage video images
for display.
Some graphics can be Integrated, which means it’s wired onto the circuit
(mother) board.
Video cards are separated devices that you can buy and install
You can update integrated graphics
Video Cards are usually more powerful
VS
PCI (Peripheral Component Interconnect)
PCI –E (Peripheral Component Interconnect Express)
AGP (Accelerated Graphics Port)
All are different kinds of video ports for a computer’s motherboard. The
difference between these are the pin holes.
AGP Supports PCI/PCI-E Supports
No
It’s a matter of preference.
AGP supported graphics cards usually have better support drivers but lack
in processing power
PCI/PCI-E has better processing power and lack in support drivers
Most have a GPU
Takes load off:
-CPU
-Video Memory
-Video BIOS
Video cards contain their own RAM usually in 128MB or 250MB
Video cards are an add-on to a computer’s motherboard that processes
images and display them. It helps process video memory for the CPU, RAM,
and video BIOS so it won’t bog down the computer.
