DVI is Digital Visual Interface. It is a relatively new video interface standard. This type of interface provides enhanced visual quality, particularly on digital displays such as flat-panel LCDs and digital projectors. The standard DVI is developed to maximize the video quality of LCD's. DVI is a type of connection between videos, like LCD monitors and CRT's, while AGP is a type of relationship used between mainboards and video cards.
AGP is an interface specification on mainboards and a graphic card, whereas AGP is a shortened term for Accelerated Graphics Port. It is a much-used interface specification developed by Intel. AGP is designed to help facilitate your computer to communicate with the graphics card in a convenient, enthusiastic, and practical way.
DVI and AGP are two types of connections. DVI stands for Digital Visual Interface, and it provides a connection between displays and video cards. AGP stands for Accelerated Graphics Port, and it provides a connection between video cards and mainboards. AGPs are also referred to as bus slots.
DVIs work with traditional cables and plugs, while AGPs work on mainboards and graphics cards. DVIs also work with the conventional digital and analog signals. AGPs allows the graphics card and computer to communicate with one another. DVIs are what make digital displays work, while AGPs help our machines perform better.
