Difference between dedicated and shared graphics card

What a question. I remember hearing those words when I’m still working at Dell Philippines (so bad that this badge site of Dell in Philippines was bought by a BPO company. Now it owns by Teleperformance. Turning back, a dedicated graphics card has its own graphics chip attached to the card itself. They come usually with 3 basic types of add in cards namely PCI, AGP, and PCI-Express cards. It has its own memory that whatever the video card is doing, the memory of the system will not be altered or decreased. An example of this kind is shown.

For a shared graphics card, the memory being used by it is being borrowed from the system memory. Meaning, if much is being used by the graphics card like for example playing an extensive video game, your computer might go slow or the resolution will not be that good. If asked what is best to use, a dedicated graphics card because it doesn't borrow memory from the system, so your computer will neither run faster nor slower when extensive video editing or playing is happening on the pc.
