Which safeguard protects the computer from unauthorized access by translating files into a code?

The safeguard that protects a computer from unauthorized access by translating files into a code is called encryption. Encryption transforms readable data into an encoded format that can only be deciphered with a specific key or passWord, ensuring that even if data is intercepted, it remains secure and unreadable to unauthorized users. This process is essential for maintaining confidentiality and integrity in data transmission and storage.
