Interlingual machine translation is one instance of rule-based machine-translation approaches. In this approach, the source language, i.e. the text to be translated, is transformed into an interlingual language, i.e. a language neutral representation that is independent of any language.
Like a motherboard, a graphics card is a printed circuit board that houses a processor and RAM. It also has an input/output system (BIOS) chip, which stores the card's settings and performs diagnostics on the memory, input and output at startup. A graphics card's processor, called a graphics processing unit (GPU), is similar to a computer's CPU. A GPU, however, is designed specifically for performing the complex mathematical and geometric calculations that are necessary for graphics rendering.
But graphics cards change that. Once installed and it's drivers have been downloaded it handles all the visuals on the screen. When playing games it handles all of the rendering and stuff. So, for basic needs a graphics card isn't that important, but if you are a gamer then it is a necessity.
