Applying
Masking - A process which will reveal the value of a specified bit, within a binary number. Eg. 1001 0110 AND 0000 0100 = 0000 0100. This shows that the 3rd bit is a 1.
Clearing a register - Using the mask 0000 0000 and applying an AND operation to any binary number will clear it.
Encryption - Data can be encrypted, where the data is scrambled up, allowing a safe transmission. It is then decrypted at the other side.
Hashing - Hashing will apply an algorithm to data, making it unreadable. This isn't reversible, so it is mainly used for storing passwords.
