What is a Graphics Card ?

• A graphics card is the component in your computer that handles generating the signals that are sent to the monitor or “graphics”.
• It is responsible for generating all the text and pictures that are displayed on your screen.
• The images you see on your monitor are made of tiny dots called pixels.
• At most common resolution settings, a screen displays over a million pixels, andthe computer has to decide what to do with everyone in order to create an image.
• To do this, it needs a translator — something to take binary data from the CPUand turn it into a picture you can see.
• This task is performed by Graphic Card which is built into motherboard.
• A graphics card’s job is complex, but its principles and components are easy to understand.
• The CPU, working in conjunction with software applications, sends information about the image to the graphics card.
• The graphics card decides how to use the pixels on the screen to create the image.
• It then sends that information to the monitor through a cable.
• To make a 3-D image, the graphics card first creates a wire frame out of straight lines. Then, it rasterizes the image.
• It also adds lighting, texture and colour.

The graphics card accomplishes this task using four main components:

1. A motherboard connection for data and power
2. A processor to decide what to do with each pixel on the screen
3. Memory to hold information about each pixel and to temporarily store completed pictures
4. A monitor connection so you can see the final result
