Encryption is taking straight text and scrambling it for security purposes. Businesses are required by law (Sarbanes Oxley is one I'm familiar with) to protect the data they hold.
No, but its there if you want it.
Encryption
Assigning a code to represent data is known as encryption. Encryption uses algorithms to alter data in a specific way so that it become unreadable to anyone without the necessary information to decrypt the data.
People have developed many encryption algorithms. One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.
"Evaluating cryptography is difficult since without 'breaking' the encryption its hard to say whether one encryption is better or not. Pretty Good Encryption (PGP) is asymmetric, that is the encryption and decryption keys are different which may give it an edge on symmetric encryption."
Basic encryption (up to 256 bit encryption) software costs around $400 per year. Encryption softwares are not 100% foolproof.
Encryption
what does the word skit stand for in encryption
Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.

WEP encryption is being used.
