Final answer:
a) Integrity is the term used to describe data that has not been altered and remains identical to the original source, ensuring its accuracy and consistency within a system.
Step-by-step explanation:
The term that means the data on a system is the same as the data from the original source and has not been altered is integrity. In the context of information security, integrity refers to the accuracy and consistency of data. This is one of the core principles of information security, alongside confidentiality and availability, commonly referred to as the CIA triad. Ensuring data integrity means protecting it from unauthorized changes that could occur due to various factors such as human error, malicious attacks, or system malfunctions. Techniques to preserve data integrity include access controls, version controls, and checksums.
Integrity means that the data on a system is the same as the data from the original source. It has not been altered. In the context of computer systems and data, integrity refers to maintaining the accuracy, consistency, and reliability of data throughout its lifecycle.
For example, let's say you have a file that contains important information. If the file's integrity is intact, it means that the data in the file has not been modified, tampered with, or corrupted since it was created or last verified.
