What is the primary function of a toolbar in computer applications?

The primary function of a toolbar in computer applications is to offer selectable image buttons for various functions. Toolbars are designed to provide quick and easy access to frequently used commands and features. These buttons often represent common actions like saving a file, printing, or formatting text, allowing users to perform these tasks with a single click rather than navigating through menus. This enhances user productivity by streamlining workflow and providing a visually intuitive way to interact with the application.

Each button on a toolbar typically includes an icon that visually represents its function, making it easier for users to find and use specific features quickly. The design of toolbars is based on the principle of usability, where the goal is to make the most common operations accessible at a glance, thus improving the overall user experience in software applications.
