    Processing power and storage space is very valuable on a computer. To get the best out of both, it can mean that we need to reduce the file size of text, image or audio data in order to transfer it more quickly and have it take up less storage space. Compression addresses these issues.

    Below are three examples of compression on the same image. Match each version of the image with the description.

    • Original file format, large file size but very detailed image

    • Compressed file format, medium file size and moderately detailed image

    • Compressed file format, small file size and not a very detailed image

      a. 


      PNG format

        b. 


        JPEG format

          c. 


          BMP format
