Graphics Card

A graphics card's job is complex, but its principles and components are easy to understand. In this article, we will look at the basic parts of a video card and what they do. We'll also examine the factors that work together to make a fast, efficient graphics card.

Think of a computer as a company with its own art department. When people in the company want a piece of artwork, they send a request to the art department. The art department decides how to create the image and then puts it on paper. The end result is that someone's idea becomes an actual, viewable picture.

A graphics card works along the same principles. 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.

Tower

A computer tower, also known as a computer case, is the enclosure that holds many components of a personal or office desktop computer. Towers can come in a wide variety of shapes and sizes, and they can be made from a wide range of materials, including steel, plastic, and aluminum. Sizes range from small mini-towers to medium sized mid-towers and all the way up to full-size towers, depending on what the computer is being used for and how powerful it is.


There are several computer components that can be commonly found in the tower of a home or office computer: the motherboard, hard drive, power supply, and any optical drives or floppy drives, as well as other parts. The locations of these components within the computer tower is usually dependent upon the size or shape of the tower itself, but they are also typically found in the same places in most computers for the sake of convenience. For example, the CD, DVD or floppy drives can usually be found in the front for easy access, while the power supply is usually located in the back to keep the cords out of the way.
