Explains screen actions describes one function of a graphics processing unit (GPU)

Explanation:

A Graphics Processing Unit (GPU) is a single-chip processor fundamentally employed to maintain and expand the representation of video and graphics. A GPU is not only used in a PC on a video card or motherboard, but it is also used in mobile phones. This phase is also known as a visual processing unit.

A GPU can contribute images extra quickly than a CPU because of its parallel processing architecture. Moving data into the graphical style and then using the GPU to scan and analyze it can create a huge speedup.
