COMPUTER FUNDAMENTALS

Detailed explanation-1: -Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer. This method is performed by un-encrypting the text manually or by using keys used to encrypt the original data.

Detailed explanation-2: -Data encryption converts data from a readable, plaintext format into an unreadable, encoded format: ciphertext. Users and processes can only read and process encrypted data after it is decrypted. The decryption key is secret, so it must be protected against unauthorized access.

Detailed explanation-3: -The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.

Detailed explanation-4: -Encryption is the process of converting data into an unusable form and does not itself stop hacking or data theft. Instead, it prevents stolen content from being used, since the hacker or thief cannot see it in plaintext format.
