Any computer requires hardware so that it can be made to work. The hardware is what allows us to gain access to the software. Without the hardware it would be difficult to make use of the computer at all because the software would be totally inaccessible. So to gain access to cyber-space, it is important to have the portal one would need to be able to look at and make use of everything the software has to offer.
The video board is one such hardware. Everything seen on the screen is the product of the video board which enables the computer to display 3-D images, graphics for computer games, movies and other movies of the sort. These are all shown on the screen because of the videoboard. Basically everything that is stored in the videoboard is what is shown on the screen and, is part of the software.
The software has many different names- it is also referred to as the video adaptor, display card, video card and the display adaptor. These are just some of the alternate names for the video board. It is possible to integrate the video board into the motherboard or one could even attach this to the CPU. Nowadays the video board is attached to the motherboard itself and so, there is no need to purchase this separately. If you prefer getting these separately you’d need to get the previous versions of the PC since all PCs that are made now integrate the video board with the motherboard.
This way it would be possible for the video board to be read by the computer and the video board would then act as the expansion port which can be used in order to read the video card. These devices have their own RAMs (Random Access Memory) and can be used in order to store videos and pictures.
The graphic card has heat sinks and this can be used in order to spread out the heat emitted by the card itself. This would prevent the card from getting burnt or be affected by the amount of heat built up inside the card itself. This has video memory. The video memory as suggested by the title is the amount of memory the card has so that it could store such information. This is what the video board reads and brings on to the screen.
