Which process involves repeating similar operations until a condition is fulfilled?

The process described involves repeating similar operations until a specific condition is met, which characterizes iteration. In programming, iteration refers to the repeated execution of a block of code as long as a defined condition remains true. This is commonly implemented through loops, such as 'for' loops or 'while' loops, where the code inside the loop runs multiple times, executing repeatedly until the exit condition is satisfied.

In contrast, recursion involves a function calling itself to solve smaller instances of the same problem, but it usually relies on a base case to stop the process. Encryption is a method of transforming information to protect its confidentiality and does not inherently involve repetition based on a condition. Data analysis is the process of inspecting and interpreting data, which may involve operations but does not specifically focus on the repeated execution of processes based on a condition. Thus, iteration is the correct term that aligns with the definition provided in the question.
