A(n) _ is an action that causes something to happen. a code b event c program
The Correct Answer and Explanation is:
Correct Answer: b. event
Explanation:
An event is an action that causes something to happen in a computer program or system. In computing and programming, events are used to trigger specific pieces of code when certain conditions or actions occur. These actions can include a user clicking a button, pressing a key, moving the mouse, receiving a message from the internet, or even the completion of a timer.
Events are central to event-driven programming, a common paradigm in software development, especially in graphical user interfaces (GUIs), games, and web development. When a user interacts with a software interface, such as clicking a “submit” button on a form, that interaction is considered an event. The system detects the event and executes a pre-defined block of code that responds to it.
A code refers to the actual instructions written by a programmer. Code is used to tell the computer what to do. While code responds to events, it is not the action itself. Rather, it is the content or instruction that runs because of an event.
A program is a complete set of instructions that the computer follows. It includes many components such as functions, variables, loops, and events. Although a program may contain many events and corresponding pieces of code, the program as a whole is not the single action that causes something to happen. It is the larger structure or container within which those events are defined and handled.
Therefore, in the context of what causes an action to occur in a system, an event is the most accurate choice. It is the occurrence or trigger that leads to a response from the system through the execution of relevant code.
