A term to describe equipment that can work in more than one resolution. Dedicated TV equipment is designed to operate at a single resolution although some modern equipment, especially that using the ITU-R 601 standard, can switch between the specific formats and aspect ratios of 525/60 and 625/50. By their nature, computers can handle files of any size, so when applied to imaging, they are termed resolution independent. As the images get bigger, so the amount of processing, storage, and data transfer demanded increases in proportion to the resulting file size. So, for a given platform, the speed of operation slows. Other considerations when changing image resolution may be reformatting disks, checking if the RAM is sufficient to handle the required size of file, allowing extra time for RAM/disk caching, and how to show the picture on an appropriate display.
