What Is a Video Controller?

ASUS Graphics Card

A video controller, or video card and graphics card as they’re now more commonly known, is an expansion card whose function is to come up with output images to a display. When pertaining to early machines, the cardboard is typically named a video controller or graphics controller, when the cards were typically integrated onto the motherboard itself.

Purpose of a Video Card
Think about this scenario for a moment: you’re asking a neighborhood resident for directions to a hotel. you can not understand anything this person is telling you irrespective of how hard you listen. After some exchanges of dialogue, you’re able to obtain the directions and make your thanks to the hotel. A video card works in the very same way. Without it, an image would never appear on our computer monitors and we would constantly be viewing a blank screen, making the pc completely useless.

Components Needed
While a computer relies on a graphics card to properly function, the graphics card relies on other components of a computer to properly function likewise. For a graphics card to try to do its job, a computer must a minimum of having these four components: a motherboard to inform it what to try to do, a processor to offer it the ability needed to perform its tasks, a memory that will help hold the photographs created and distribute it during a timely manner, and a monitor to display images created.

The GPU
You probably, to some extent, understand the fundamentals of a motherboard. you most likely know that it’s the brain of a computer that houses the processor and memory. A graphics card has identical qualities. Very like a motherboard incorporates a CPU, a graphics card features a GPU (graphics processing unit). The GPU behaves very similarly to a CPU therein it’s designed specifically for drawing displays and is chargeable for performing complex mathematical and geometric calculations that have got to be processed for graphics rendering. Very like a CPU is the heart of a computer, the GPU is the heart of the graphics card.

How a GPU Works
As stated, the GPU is the heart of the video card and is the component that does the particular work. To understand how a video card works, you need to realize how the GPU works. The GPU uses special programming created for the video card to research and use data that are wont to create images for display on the monitor. Once the GPU creates the image, it stores the data it’s created into the video card’s RAM for later use.

Tying it all at once
As stated, a video card is essentially a graphical translator for the pc. As a whole, the graphics we view on our monitors daily are nothing quite pieces of binary data. From the state-of-the-art graphics we see in our computer games to the icons on our desktop, every pixel that creates up what we see is nothing quite a series of numbers translated into graphics because of the video card.
