Understanding Image Representation in Computer Systems

What are the two main methods of storing images in a computer system?

• Bitmap and Raster

• Vector and Raster

• Bitmap and Vector

• Pixel and Vector

What is the main advantage of using vector images over bitmap images?

• Better for photographs

• Smaller file size for technical drawings

• Easier to store in binary

• More colors available

In a bitmap image, what is each colored square called?

• Pixel

• Coordinate

• Bit

• Vector

What is the binary value for a black pixel in a simple black and white bitmap image?

• 0

• 10

• 1

• 11

What additional data is needed to reconstruct a bitmap image from raw binary data?

• Metadata

• Resolution

• File size

• Color palette

What does metadata in a bitmap image include?

• Width, height, color depth, and color palette

• File size, resolution, and color depth

• Width, height, and file size

• Resolution, color depth, and file size

How many colors can be represented with 2-bit color depth?

• 8

• 16

• 4

• 2

What happens to the file size as the color depth and resolution of a bitmap image increase?

• It fluctuates

• It increases

• It remains the same

• It decreases

How many colors can be represented with 24-bit color depth?

• Over 1 million

• Over 16 thousand

• Over 16 million

• Over 256 thousand

What is the hexadecimal representation used for in modern image storage?

• To store metadata

• To simplify binary representation for humans

• To increase file size

• To reduce color depth
