COMPUTER FUNDAMENTALS

Detailed explanation-1: -Data encryption is the process of converting data from a readable format to a scrambled piece of information. This is done to prevent prying eyes from reading confidential data in transit. Encryption can be applied to documents, files, messages, or any other form of communication over a network.

Detailed explanation-2: -The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted over the internet or any other computer network. In addition to security, the adoption of encryption is often driven by the need to meet compliance regulations.

Detailed explanation-3: -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-4: -Users who are not authorized cannot open, copy, rename or move the encrypted file or folder. Instead, they see a warning message like access denied, depending on the application trying to access the file or its data.

Detailed explanation-5: -With data breaches and identity theft on the rise, encrypting files not only means protecting an organization’s reputation and trustworthiness-it means protecting people and their valuable assets. File encryption is also a key pillar of cybersecurity, with national and global policies requiring its use.
