What is a macro in computing?

A macro in computing is best defined as a group of commands that are executed to automate multiple tasks. Macros allow users to perform repetitive actions efficiently by recording a sequence of commands and then playing them back with a single command or keystroke. This is particularly useful in applications like spreadsheets or word processors, where users frequently perform the same set of actions, such as formatting text or applying formulas.

By using macros, tasks that would typically require several steps to complete can be condensed into one action, saving time and reducing the likelihood of errors in manual input. This makes them a powerful tool for enhancing productivity in various software applications.

The other choices do not accurately represent what a macro is. While one option refers to a storage device, that relates to physical memory rather than command sequences. Another option describes a software program, but macros are specific functionalities within software rather than standalone programs. Lastly, a hardware component relates to the physical parts of a computer, which does not pertain to the concept of a macro in computing.
