A set of instructions that repeats until a specific condition is met is known as a loop. Loops are fundamental constructs in programming that allow for the execution of a block of code multiple times, which is particularly useful for tasks that require repetition, such as iterating through a list or continuing to process user input until a certain state is reached.

The defining feature of a loop is its condition, which is checked before or after each iteration. If the condition evaluates to true, the instructions within the loop will continue to execute; once the condition is no longer met, the loop terminates, allowing the program to proceed to the next section of code. This mechanism provides a powerful means of controlling the flow of a program, making loops essential for writing efficient and concise code.

In contrast, a procedure refers to a block of code that can be called to perform a specific task but does not inherently involve repetition. A function is similar in that it also encapsulates code for reuse and can return a value; however, it does not denote a repeated execution by itself. A module, on the other hand, refers to a collection of related procedures and functions that form a larger component of a program, rather than focusing specifically on the concept of repetition found in
