Which term relates specifically to computer operations?

The term that relates specifically to computer operations is "computational." This term encompasses the processes and calculations that a computer performs when executing programs or algorithms. It refers to the nature of the tasks that computers are designed to carry out, which include processing data, performing arithmetic operations, and executing algorithms to solve problems.

In the context of computer science, computations are fundamental to how software and applications function. The other terms, while related to aspects of computing, do not specifically address the operations that a computer performs. "Database" refers to structured collections of data, "interface" pertains to the means by which a user interacts with the system, and "variable" is a programming concept that represents storage locations with value names. Each of these plays a role in computing, but "computational" directly ties to the operational processes inherent in computing technologies.
