SSC MTS EXAM

Detailed explanation-1: -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-2: -Full Disk Encryption (FDE) or whole disk encryption protects the entire volume and all files on the drive against unauthorized access. In contrast to FDE, File-Level Encryption (FLE) is an encryption method, which takes place on the file system level, enabling the encryption of data in individual files and directories.

Detailed explanation-3: -RSA: RSA, named after computer scientists Ron Rivest, Adi Shamir, and Leonard Adleman, is a popular algorithm used to encrypt data with a public key and decrypt with a private key for secure data transmission.

Detailed explanation-4: -Computer security, also called cybersecurity, is the protection of computer systems and information from harm, theft, and unauthorized use. Computer hardware is typically protected by the same means used to protect other valuable or sensitive equipment-namely, serial numbers, doors and locks, and alarms.
