Task (Int 2)
Research 3 different graphics cards. Copy and complete the table below for each one.

Task (Higher)
Investigate the following aspects of a graphics card:
 * Graphics Processing Unit (GPU)
 * Video RAM (VRAM)
 * Digital Signal Processor (DSP)
 * Digital Visual Interface (DVI)
 * Digital-Analogue conversion (DAC)

In a blog post write a short description about each of the above, explaining its purpose in terms of graphics output.
