What is video(graphics) memory good for ?(all answers will be read)?

Theres a laptop with 384 mb of shared graphics memory and 512 mb of dedicated . The other has 1023 mb of shared graphics memory but only has 256 mb of dedicated . I don't even know what video memory is , so if you have anything helpfull to say that would be good .

Video memory (aka VRAM) is simply the amount of memory alloted to various tasks such as watching movies, playing games etc from its respectable graphics card whether separate or onboard. Ideally the more memory there is available the better the performance and efficiency. Shared memory means the memory is shared between different hardware components such as I/O, RAM etc as well as the visuals itself. Separate cards are better, but onboard cards run quicker as they are hardwired directly to the motherboard.

so that it is not running on the internal memory alone,doing so would take up to much memory, and slow down the computer alot, graphic memory give a fast reproduction of games, video, and other graphics intensified system usage

Shared memory in my opinion is always problematic.

Graphic memory is usually on the graphic card and is called vRAM, Dedicated memory is RAM and sits in its own slots on the motherboard and holds information for rapid access.

At the lower end of the computer market there are machines with shared memory, where the graphic card has no built-in memory but uses some of the RAM on the motherboard. This always results in an inferior performance.

As a rule of thumb I would suggest most good performing graphics card have 256 - 320 onboard vRAM, and for XP a minimum of 512motherboard RAM is necessary and for Vista 1GB though realistically you should double for both.

RAM is becoming important in computing for it affects performance.

My advice if you can afford it, is to try and get a laptop with a separate RAM and vRAM.

i appreciate with answer 1 .

basically the video graphic cards depend upon its memory and and and....and a processing speed of integrated processor and memory (bole to Frequency ) . The shared memory doesnt ve enough speed comparision to inbuilt ie dedicated memory with inbuilt processor of video card. For gaming and watching movies at high graphics all u need 256 mb ram in this date(sufficient) but actual High graphical Games are in demand these days ,bulky graphics caching is needed at a very high frequency and thus required a lot of memory to allocate storage immediately . So i recommend 512 mb dedicated graphics memory for gamers for efficient result ,doesnt matter how much shared memory is..ya there shud be a shared memory also but dedicated memory is must in all the way of thinking. In other words , priority must go to dedicated memory of video graphic card first and then shared .
