The term "high resolution" refers to a level of detail or clarity in an image, video, audio recording, or data set. It describes how much information is contained within a particular representation and can be used to describe the quality of these representations. In other words, high-resolution means that there are many small details present in the image or data, allowing for greater accuracy and precision when analyzing it. This term is commonly used in reference to digital images, where higher resolution means more pixels (small squares of color) per inch, resulting in a clearer and sharper picture. High-resolution imagery can be particularly important in fields such as medicine or engineering, where precise measurements are necessary for accurate analysis.
