Explain the following terms: i) Persistence ii) Resolution iii) Aspect ratio iv) Pixel v) Refresh Buffer
Understand the Problem
The question is asking for explanations of specific terms related to imaging and display technology. We will define each term and provide relevant context for better understanding.
Answer
Persistence: Light decay time on screen. Resolution: Pixel count displayable. Aspect Ratio: Width to height ratio. Pixel: Smallest display element. Refresh Buffer: Stores pixel data for screen refresh.
i) Persistence: The time it takes for emitted light from a screen to decay to one-tenth of its original intensity. ii) Resolution: The number of distinct pixels that can be displayed on a screen. iii) Aspect Ratio: The proportional relationship between the width and height of a screen or image. iv) Pixel: The smallest controllable element of a picture on a display screen. v) Refresh Buffer: A memory buffer used to store pixel data that the display controller uses to refresh the screen.

More Information
These terms are crucial in understanding display technology and computer graphics. The persistence of a display influences how smooth the visual transitions appear, while resolution and aspect ratio determine clarity and the form of content presentation. Pixels are fundamental building blocks of digital images.
