- 25.What function is being described below: When a command or string is repeated over and over again, in order to reduce the amount of uneccessary data, the status byte, if repeated, is only sent once. The significance of a data byte always beginning with a 0 and a status byte always beginning with a 1 allows the system to instantly tell if it has recieved a data byte or a status byte. As a result if there are a string of note on message for example, rather than sending Status Byte, Data Byte 1, Data Byte 2, Status Byte, Data Byte 1, Data Byte 2, Status Byte, Data Byte 1, Data Byte 2. It would remove the 2nd and 3rd status bytes and instead send; Status Byte, Data Byte 1, Data Byte 2, Data Byte 1, Data Byte 2,

Running Status
- C.
Compression
- D.
