MIL-STD-1553B, RAID, etc. Flashcards
Define MIL-STD-1553B
A multiple redundant balanced line with TDM that uses a half-duplex command/response protocl and can interface up to 30 remote terminals
What are the 6 types of transfer on MIL-STD-1553B
Controller to RT Transfer
RT to Controller Transfer
RT to RT Transfer
Mode Command Without Data Word
Mode Command With Data Word (Transmit)
Mode COmmand with Data Word (Recieve)
Define NTDS Type-E
Naval Tactical Data System Type-E
Provides asynchronous serial data transfer at 10Mb/s and uses Manchester encoding
Define Super Channel
A Dense Wavelength Division Multiplexing (MWDM) scheme that combines coherent optical carriers to create a unified channel with a high data rate.
Define RAID
Redundant Array of Independant Disks
Protects stored data against read erros and hardware faults.
What is RAID 0?
Striping only.
Faster read/write times, no protection.
What is RAID 1?
Mirroring only.
Slow read time but provides protection.
Define RAID 2
Bit level striping with parity
Define RAID 3
Byte level striping with parity
Define RAID 4
Block Level striping, with parity
Define RAID 5
Block level striping with distributed parity.
Minimum 3 drives required.
Define RAID 6.
Block level striping with double distributed parity.
Define RAID 10.
RAID 5 twice (mirroring)
