Answer Key

Graphics processing unit (GPU)

Section A: Quick Questions

A — Images and video to show on a screen

B — It is a component that speeds up graphics work

A — A GPU built into the CPU

B — A separate graphics part with its own power for graphics

A — Playing a detailed 3D game

Section B: Match the Pairs

GPU → Graphics processing unit: a component specialised for processing images and video to display on a screen

dedicated GPU → A separate graphics component with its own power and memory, good for games and video editing

A GPU built into the same chip as the CPU, used for everyday tasks like browsing and watching videos → integrated GPU

The part of the computer that does the main thinking and general tasks, while the GPU focuses on graphics → CPU vs GPU

The GPU stores all of your files and photos permanently. → A GPU does not store files. Storage devices do that. The GPU processes images and video to show on the screen.

A GPU is only needed for typing and not for games or video editing. → Games and video editing need lots of image processing, so they rely on the GPU the most.

Section C: Definitions

GPU — Graphics processing unit: a part that quickly processes images and video to show on a screen. It can be built into the CPU (integrated) or separate (dedicated).

Section D: Fill in the Blanks

A GPU processes images and video fast

GPU stands for graphics processing unit

An integrated GPU is built into the CPU

A dedicated GPU is separate and more powerful

CPU = general tasks, GPU = graphics tasks

Section E: Spot the Error

B — A single = assigns a value. To compare gpu_type with 'dedicated' in the if statement, use ==.

C — The print call is missing its closing bracket. It should be print('Use the GPU').

A — The text integrated needs quotes to be a string. Without them Python looks for a variable called integrated. It should be gpu = 'integrated'.

D — The string is missing its closing quote. It should be print('Smooth graphics').

A — A function definition must end with a colon. It should be def render(frames):.
