What is a video card? What's the use of computer graphics?

Graphics card believe that often contact with the computer's friends are not unfamiliar, especially the game users on the graphics card is more love, then what is the video card? What is the function of the video card in the computer? For the first contact with the computer really do not understand, today computer Pepsi Network Editor took out his previous computer tutorial, will be some conceptual things here to share to novice friends.

Highly recommended for beginners to read: computer hardware knowledge literacy must look at Computer Configuration knowledge How to see Computer graphics card

What is a video card, what is the function of the video card?

Generally speaking, the video card is to control the output of the computer image, we like to hook up with the video, in fact, the video is also a combination of pictures, through a display of a number of consecutive images combined into a video, so the professional graphics card is graphics adapter, as long as you know the graphics card and computer display has a great relationship.

Professionally speaking, the graphics card is also called video card, video adapter, graphics card, graphics adapter and display adapter and so on. It is the connection between the host and the "Bridge", the role is to control the computer's graphics output, is responsible for the CPU sent to the image data processing into the format of the display, and then sent to the monitor to form an image. Graphics card mainly by the display chip (that is, graphics processing chip graphicprocessingunit), video memory, digital-to-analog converter (RAMDAC), Vgabios, various aspects of the interface and other components.

Graphics card According to the structure can be divided into 2 categories, which is what we often call the independent graphics and integrated graphics 2 categories. Discrete graphics refers to the display chip, video memory and its associated circuit on a single board, self-contained and as a separate board exists, it needs to occupy the expansion slot of the motherboard. Discrete graphics by interface type divided into ISA graphics, PCI graphics, AGP graphics, PCI-E graphics, etc., ISA graphics card, PCI video card has been eliminated, AGP graphics card is also facing elimination, PCI-E graphics card is now popular graphics card, its interface transfer speed is the fastest. Integrated graphics, integrated video card is the display chip, video memory and its related circuits are made on the motherboard, and integrated with the motherboard, integration of the video card display chip has a separate, but now most are integrated in the motherboard of the North Bridge chip; some motherboard integrated graphics cards also have a separate video memory on the motherboard, but their capacity is small, At present, most of the integrated graphics cards do not have a separate video memory, the use of system memory to act as memory, its use is automatically adjusted by the system, the integrated graphics display and performance is poor, the video card can not be hardware upgrade, the advantage is that the system power consumption has been reduced, no need to spend extra money to purchase video card.

Since the discrete graphics card has its own module, including its own cache, and a slightly better discrete video card has a cooling fan, so we can see that the independent graphics card technology is also more advanced than integrated graphics, more than the integrated graphics can be better display and performance, easy to video card hardware upgrade , the disadvantage is that the system power consumption has increased, heat is also larger, more suitable for the configuration display performance of the game users to choose, and integrated graphics mainly suitable for computer performance requirements are not high, general Internet, play simple game users choose.

questions about the common beginner of graphics cards? video card temperature is too high what to do?

Can I have a computer without a video card?

A: Many novice friends often say that the computer does not have a video card, in fact, is not independent of the use of discrete graphics card, but the motherboard has at least integrated graphics card, where the editor means that the computer can not have a video card, the reason is the computer if the graphics adapter is not and how can show the picture? So most friends say that the integrated configuration is not a separate video card selection, but the use of the motherboard integrated graphics.

Are all motherboards integrated with the first video card?

A: Not all motherboards have integrated graphics, specifically need to see the motherboard parameters

Is there an integrated video card in the motherboard in the computer and can I use a discrete video card?

A: Yes, when the integrated platform computer does not meet the game needs can be added separately with the independent graphics upgrade performance, computer display performance will be greatly improved.

Introduced here, I believe that you should have a more comprehensive understanding of the graphics card, if you have any questions about the video card, welcome to connect us.
