• The internet provides platforms like email, social media, instant messaging, and websites for global interaction and data exchange.

What is colour depth and how does it affect image quality?

• Color depth is the number of bits used to represent the color of a single pixel in an image. It affects image quality by determining the range of colors that can be displayed, with higher color depths allowing for more colors and better quality.

• Color depth determines the resolution of an image

• Color depth is the size of the image file

• Color depth refers to the brightness of an image

Define pixels and their role in displaying digital images.

• Pixels are microscopic organisms that create images

• Pixels are mathematical equations that generate images

• Pixels are sound waves used to display images

• Pixels are the building blocks of digital images, forming the visual content by combining different colors and intensities.

What is resolution and why is it important in digital imaging?

• Resolution is the type of camera used and is important for image composition.

• Resolution is the size of the image file and is important for storage space.

• Resolution is the brightness of the image and is important for color accuracy.

• Resolution is the number of pixels in an image and is important for image quality and clarity.
