COMPUTER FUNDAMENTALS

Detailed explanation-1: -Encryption-a process of encoding messages to keep them secret, so only “authorized” parties can read it. Decryption-a process that reverses encryption, taking a secret message and reproducing the original plain text.

Detailed explanation-2: -The need for secrecy when sending bits over the Internet is important for anyone using the Internet. “Encryption” is a process for transforming a message so that the original is “hidden” from anyone who is not the intended recipient. Encryption is not just for the military and spies anymore.

Detailed explanation-3: -The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek (kryptos), or hidden and (graphia), or writing.

Detailed explanation-4: -An example of decryption is if a vendor receives an email from their client with a document detailing the requirements for their latest project. When they open the email, the details read as plain text, but their system decrypts the data upon receipt.

Detailed explanation-5: -Encryption is the process by which a readable message is converted to an unreadable form to prevent unauthorized parties from reading it. Decryption is the process of converting an encrypted message back to its original (readable) format.
