Definition
Analog data refers to continuous, real-world information that is represented by a range of values. It can take on any value within a given range and is often used to describe physical quantities like temperature or sound.
Digital data refers to information that is represented using discrete, binary values (0s and 1s). It is commonly used in computers and other digital devices because it can be easily stored, processed, and transmitted.
Sampling: Sampling is the process of converting analog data into digital form by measuring its value at specific intervals.
Resolution: Resolution refers to the level of detail or precision in representing analog or digital data. In the context of images, higher resolution means more pixels and finer details.
