An applet is a small, self-contained computer program designed to perform a specific task or provide a specific function within a larger software application or web page. Unlike traditional programs, applets do not need to be installed on a user’s computer and can be run directly from a web browser. They are often used to enhance the functionality of websites, such as interactive games, calculators, or multimedia content. Applets are typically written in Java or other programming languages and are easily accessible and portable, making them a popular choice for creating dynamic and interactive online experiences.
