Answer» 12. Encryption is the process of transforming information so it is unintelligible to anyone but the intended recipient. Decryption is the process of transforming encrypted information so that it is intelligible again. 13. Development software is a set of programs that helps someone to write new software and make sure it is working correctly. 14. A backup utility is used to create a copy of data from your database that can be used to reconstruct that data. It ensures that the data is safe and accessible at a later instant. 15. No matter how carefully you operate your PC or laptop, you still need a proactive protection to safeguard your computer from malicious software. Antivirus softwares are programs that help protect your computer against most viruses and other unwanted invaders. |
