Which of the following image file formats is known as an uncompressed raster file?

The choice of BMP as the correct answer highlights its nature as an uncompressed raster file format. BMP, or Bitmap, is designed to store pixel data in a straightforward manner without applying any compression. This results in higher image quality since all pixel information is retained exactly as it was captured.

Raster images are made up of a grid of pixels, and the BMP format effectively preserves this grid without reducing the quality through compression techniques. This can lead to larger file sizes, but it ensures that the visual details remain intact. In contexts like printing or professional image editing, where clarity and detail are crucial, using BMP can be highly advantageous.

Other formats listed, such as JPEG and PNG, employ different methods for compression. JPEG uses lossy compression to reduce file size at the cost of some image quality, making it suitable for photographs but not ideal for images needing high fidelity. PNG, on the other hand, uses lossless compression which does preserve image quality but is still considered compressed compared to BMP. SVG is a vector format, not raster, and typically involves mathematical definitions of shapes rather than pixel data, which further separates it from being categorized alongside BMP in terms of raster image types.
