What is a DCT (Destination Control Table)?
Destination Control Table (DCT) is a collection of operating system data structures that serves as a directory of named processes and logical devices. It is a collection of PCBs. In addition to a PCB associated with every process, the operating system maintains several other tables of information to keep track of processes. A collection of such tables, known as the destination control table (DCT), contains information about all named processes on the system. This table is a system-wide table and therefore remains visible even if a processor should fail.
