"Uncompressed" refers to data that has not been reduced in size through compression techniques. This means that the original quality and details of the data, such as images, audio, or video files, are preserved without any loss. Uncompressed files are typically larger and require more storage space compared to their compressed counterparts. In the context of digital media, uncompressed formats include WAV for audio and BMP for images. These formats maintain the highest fidelity, making them ideal for professional use, such as in music production or graphic design, where quality is paramount. However, they can be less practical for everyday use due to their large file sizes.
