  • Computer-readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. Additionally, computer-readable media can include both computer storage media and communication media.
  • Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules, or other data.
  • Communication media typically includes computer-readable instructions, data structures, program modules, and other data in a modulated data signal, or other transport mechanism, and includes any information delivery media.
