Which of the following best describes a vector graphic?

• An image made up of a grid of coloured squares (pixels)

• An image defined by mathematical equations and shapes

• A photograph taken with a camera

• An image that cannot be resized

What is a key advantage of using vector graphics over bitmap graphics?

• They become blurry when resized

• They can be scaled without losing quality

• They use more storage space

• They are made from pixels

Which of the following elements can be included in a vector-based logo?

• Shapes, fills, outlines, merging, grouping

• Only photographs

• Only text

• Only black and white images

What is the purpose of a fill in a vector graphic?

• To add a border around a shape

• To add colour inside a shape

• To merge two shapes together

• To group objects

What does the outline (stroke) of a vector shape refer to?

• The area inside the shape

• The thickness and colour of the shape’s border

• The merging of two shapes

• The background of the image

What does merging vector elements allow you to do?

• Change the colour of a bitmap image

• Combine two or more shapes into one

• Increase the resolution of an image

• Add more pixels to an image

What is grouping in vector graphics used for?

• To change the colour of a shape

• To treat several objects as a single unit

• To increase the number of pixels

• To add a fill to a shape

How are bitmap graphics created?

• By using mathematical equations

• By arranging individual pixels in a grid

• By grouping vector objects

• By merging shapes

What is a pixel?

• A mathematical formula

• The smallest unit of a bitmap image

• A type of vector shape

• A group of merged shapes

How are black and white bitmap images stored?

• Each pixel is stored as a single bit (0 or 1)

• Each pixel is stored as a group of shapes

• Each pixel is stored as a mathematical equation

• Each pixel is stored as a group of colours
