FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Definition: The conversion of encrypted data into its original form is called Decryption. It is generally a reverse process of encryption. It decodes the encrypted information so that an authorized user can only decrypt the data because decryption requires a secret key or password.

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: -Encryption is the conversion of data from a readable form, called plaintext, into a form, called ciphertext that cannot be easily understood by unauthorized people. Decryption is the process of converting encrypted data back into its original form (plaintext), so it can be understood.

Detailed explanation-4: -Encryption is the method by which information is converted into secret code that hides the information’s true meaning. 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-5: -Copyright, a form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture.
