Which type of software is known to execute specific commands upon receiving input?

The type of software that is known to execute specific commands upon receiving input is a bot. Bots are automated programs designed to perform tasks on the internet, often in response to specific inputs or commands. They can interact with users or other systems, enabling them to automate various operations such as retrieving information, processing data, or performing repetitive tasks without direct human intervention.

For example, a chatbot interacts with users in real time, responding to queries with predetermined or learned responses, effectively executing commands based on user inputs. This characteristic of responding and executing commands based on input is what distinguishes bots from other types of software.

In contrast, viruses are malicious programs that disrupt computer functions. Applications are software designed to perform specific user tasks, but they do not inherently execute commands in response to inputs like a bot would; they offer functionalities based on user interaction rather than automated command execution. Drivers facilitate communication between the operating system and hardware components, operating in the background without direct user command inputs.
