What does it mean to burn an image on a CD?

Answer:An ISO image is an compressed collection of various files merged into one single resulting file, They're actually images of complete CDs or DVDs compiled as one whole image file, usually created to install operating systems such as Windows or Linux. The files are burned into one unique package, then when you install the OS or program, the computer recognizes the compressed form and will expand the files within.

Is a higher kilobyte a higher resolution?

Yes and no. Higher resolution images usually require more memory to store them. However different photographic file formats may take different amounts of memory for the same resolution image (e.g. a jpg file will take less memory than a raw file for the same resolution image because the jpg is compressed and the raw is not compressed). Check the resolution of your camera to determine actual resolution, however if it saves the photos as jpg files or other compressed formats some "minor" details will be lost that would not be lost in raw files or other uncompressed formats (at the expense of needing more memory to store the files).


Are BMP files lossy or lossless?

BMP file types are lossless.BMP format stores color data for each pixel in the image without any compression. For example, a 10x10 pixel BMP image will include color data for 100 pixels. This method of storing image information allows for crisp, high-quality graphics, but also produces large file sizes.
