RAID levels
RAID 0 (block-level striping without parity or mirroring)
RAID 1 (mirroring without parity or striping)
RAID 2 (bit-level striping with dedicated Hamming-code
parity)
RAID 3 (byte-level striping with dedicated parity)
RAID 4 (block-level striping with dedicated parity)
RAID 5 (block-level striping with distributed parity)
RAID 6 (block-level striping with double distributed parity)

For example the HTTP protocol defines the format for communication between web browsers and web servers, the IMAP protocol defines the format for communication between IMAP email servers and clients, and the SSL protocol defines a format for encrypted communications over the Internet.
