COMPUTER FUNDAMENTALS

Detailed explanation-1: -Encryption is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format-called “ciphertext.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like an internet.

Detailed explanation-2: -Modern encryption takes a file and scrambles its content, sometimes also adding bits of meaningless information. It does this using an encryption key, essentially an algorithm that instructs a computer how to scramble (or unscramble) a file.

Detailed explanation-3: -Encryptionis the process of “scrambling” data to make it unreadable and only able to be read again by a person who has a code or decryption key. Without that key, the message is in “ciphertext” which renders it unusable.

Detailed explanation-4: -In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers.
