• file size sound

  (no. of bits for storing 1 second of sound) ==Bit Rate===Sampling Rate×Sampling Resolution

  ==File Size===Bit Rate * Length of Sound
• file size image


  ==File Size== = img resolution × colour depth

  resolution = w * h
• bit -> nibble -> byte -> kibibyte KiB -> mebibyte MiB -> gibibyte GiB -> tebibyte TiB -> pebibyte PiB -> exbibyte (EiB)

  2. 8 bits in byte, ==1024== bytes in KiB. 1024 mebibytes in 1 gibi byte
