Question 10


Describe in Detail


When applets are downloaded from web sites, a byte verifier performs ________?


  • When applets are downloaded from web sites, a byte verifier checks the status byte.
  • Status bytes are usually followed by one or more data bytes that provide the actual information to be implemented.
  • MIDI messages can be broken into two constituent parts: data bytes and status bytes.
  • The status byte of a MIDI message defines the type of information being sent.
  • They contain a MIDI channel, to specifically direct the information. A code tells the listening device the type of data.
  • This prepares the device to receive any one of the following eight fundamental types of MIDI data messages: Note Off, Note On, Polyphonic After touch, Control Change Program Change, Channel After touch, or System.
  • The final type, System, refers to system commands, system real time, or system exclusive commands - these are not addressed to individual MIDI channels and data bits used to specify MIDI channel are instead used to further specify the system message.
