11. Base 64 is a positional numeral system using a base of 64. It is the largest power of two base that can be represented using only printable ASCII characters. This has led to its use as a transfer encoding for e-mail among other things.






12. A computer network authentication protocol which allows individuals communicating over an insecure network to prove their identity to one another in a secure manner. Kerberos prevents eavesdropping or replay attacks - and ensures the integrity of the
