Graphics Card
The graphics card (also known as the video card and graphics adapter) is the component within the computer that has the job of transmitting images, text and all other relevant material onto the computer screen. It looks like a rectangular box with a fan inserted in it. The function of the graphics card is very important. It assists the computer (the CPU for the most part) in the process of creating images on the computer screen so that people can see their work. It does this by connecting to the motherboard and moniter. It then takes data that is in the CPU and then sends that data to the moniter. The graphic card's purpose is to help the processor with all the necessary work that is needed to put all the material onto the screen. This includes 3-D graphics. It is also a much needed component in the computer, because of its ability to help the computer get its operating system on. Students should not ignore the graphics card in the process of buying a computer. This claim is because the graphics card has a major effect on the quality of the computer. The better the graphics card, the better the overall picture that end users will experience when doing schoolwork. It is really just about having a good experience. If a student is trying to do school work but can not read the text or see videos or pictures clearly, they could become very irritated and even upset about their choice of purchase. This statement is especially important because of the new operating systems and applications that are constantly coming out that need to have the support of good graphics cards. The specifications that students should consider when buying a graphics card are a powerful GPU (Radeon HD 6850 is a good choice), sufficient video memory (1 GB to 1280 MG), high memory interface (256 bit) and a high memory bandwidth (GDDR5, for example). Also, since this computer purchase is for school, an integrated graphics card will get the job done just fine.
