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.

RAM

SD Card

VRAM

RAM (Random-Access Memory)RAM is computer data storage that can be accessed in any random order

Secure Digital Card (SD)A non-volatile memory card

Digital Camera

Video Random-Access Memory (VRAM)A dual ported variant of Dynamic RAM (DRAM)

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

Provide capabilities for today’s graphics-

intensive software like on Windows 7 or

Mac OS X.

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.
