Condensed, or compressed, refers to the process of reducing the size or volume of an object or substance. This can apply to various materials, such as gases, liquids, or even data files. In physics, compressing a gas decreases its volume while increasing its pressure, which is essential in many applications, including engines and refrigeration systems. In the context of data, compression involves encoding information to occupy less space. This is commonly used in digital media, such as images and videos, to facilitate storage and transmission. Formats like JPEG for images and MP3 for audio are examples of compressed file types that maintain quality while reducing file size.
