Encryption

What is encryption? Encryption is the act of turning a block of plain text or other raw data(such as binary computer files) into encoded blocks of text. Modern computer encryption systems use complicated techniques developed over a number of years, and are able to provide an advanced level of security.

Encryption/decryption is especially important in wireless  communications. This is because wireless circuits are easier to tap than their hard-wired counterparts. Is a good idea when carrying out any kind of sensitive transaction, such as a credit-card purchase online, or the discussion of a company secret between different departments in the organization.
