One that is used only for the video, rather than a chunk of the main memory which is shared between various tasks.
Most likely the other remaining MB is dedicated for games.
Most if not ALL modern video/graphics cards use both RAM from the MoBo and The dedicated RAM on the card.
That depends on what kind of video card you have. If you have an integrated video card (most likely) you may be able to allocate some more shared memory to the video by simply adjusting a setting in the BIOS. You can find out how to do that in the system manual. However, many BIOS config program will not allow you to allocate more than a certain percentage of system memory, so increasing your total system memory might allow you to set a higher percentage of shared memory to the video adapter. However, if you have a dedicated video card, it would have it's own memory built into it, and therefore you wouldn't be able to increase it, short of replacing that video adapter entirely with one that has more memory already on it. Check your system specs with the manufacture and see which you have, and proceed from there.
A video card or video adapter translates binary data into images.
A video card does indeed have its own memory and processor. The memory or RAM is specifically designed to store and quickly access the data required to display high-quality graphics. The processor or GPU is responsible for all of the complex calculations and operations required to generate the graphics on the screen. The RAM on a video card is usually GDDR SDRAM. The GPU on a video card is usually a dedicated graphics processor. The memory and processor on a video card are specialized for graphics processing.Having its own dedicated memory and processor enable a video card to quickly and efficiently process graphics allowing for smooth and detailed visuals. Without these components the graphics on the screen would be less detailed and more choppy.
oh yes, no dedicated no game
Many motherboards with integrated video use a certain amount of system-RAM as your video RAM. If this is the case you may be able to go into BIOS and change how much RAM is being used for this purpose. Note that in these cases increasing video RAM will decrease the amount of system RAM.Other motherboards with integrated video have dedicated video RAM built-in. In these cases your only option is to replace the motherboard or, if the motherboard has an available expansion slot, disable onboard video & install a proper video card.
you can't or you can get more ram but it only increases shared memory video!
just Graphic memory (GDDR)
integrated card
Not usually. Video card memory generally consists of ROM chips soldered directly to the card, so if the graphics card goes bad, it's best to replace it.
This is done automatically by the hardware. The onboard GPU borrows RAM to use as its own memory.
