FIrst of all, the 2 first only applies to SCSI units,

Disconnect means that the unit (theoretically) can be disconnected from the SCSI bus and later reconnected.

Sync Data Transfer is Syncronous data transfer, a slover method of tranferin data.

DMA is Direct memory access, ie utilizing a DMA channel to reduce CPU load and in some instances increase performance.
