What process involves using algorithms to scramble information on a computer?

1. Firewall protection

2. Virus protection

3. VPN protection

4. Encryption protection

The correct answer is: Encryption protection

The process that involves using algorithms to scramble information on a computer is encryption protection. Encryption is a method of converting plain text or data into a coded version, making it unreadable to anyone who doesn't have the decryption key. This process helps to secure sensitive information, ensuring that even if the data is intercepted, it cannot be easily accessed or understood by unauthorized individuals. Encryption utilizes various algorithms to transform the readable data into a format that appears random and incomprehensible. Only those with the appropriate keys can reverse the process to retrieve the original information. This is crucial for protecting sensitive data, such as personal information, financial transactions, or confidential communications, from unauthorized access and cyber threats. The other choices relate to different aspects of cybersecurity. Firewall protection involves monitoring and controlling incoming and outgoing network traffic based on predetermined security rules, providing a barrier against potential threats. Virus protection focuses on detecting, preventing, and removing malicious software from computers to safeguard against attacks. VPN protection establishes a secure and private connection over the internet, masking the user's IP address and encrypting the data transmitted during the session, but it is not specifically about scrambling data at rest or in storage. Thus, encryption protection is the specific process that uses algorithms to scramble information, ensuring its confidentiality and integrity
