Self-Study 20 (J277) 1.2 Representing images

What are the two ways of storing images in binary mentioned in the text?

• JPEG and PNG

• Raster and Grid

• GIF and TIFF

• Bitmap and Vector

What is a bitmap image made of?

• Different-coloured squares

• Mathematical equations

• 3D models

• Continuous lines

How is a vector image stored?

• Through pixel arrangement

• In a grid format

• Using mathematical formulas

• As a series of dots

What binary values are assigned to black and white in a bitmap image?

• 0 for black and 1 for white

• 1 for black and 0 for white

• 1-1 for black and 0-0 for white

• 0-0 for black and 1-1 for white

What is metadata in the context of bitmap images?

• The file format of the image

• The encryption of the image

• Data about the image's resolution and color depth

• The binary data of the image

How many colors can 2-bit color depth represent?

• 16 colors

• 4 colors

• 2 colors

• 8 colors

What does a 24-bit color depth allow?

• 64 colors

• Over 16 million colors

• 1024 colors

• 256 colors

How is 24-bit color typically represented to make it easier for humans to understand?

• Binary code

• 8-digit binary

• 6-digit hexadecimal

• RGB values

What determines the file size of an image?

• The metadata only

• The color depth and resolution

• The color palette only

• The file format only

What is the formula to calculate the number of colors that can be represented by a given number of bits?

• 2 * n

• 2^n

• n/2

• n^2
