What is WebDriver in selenium and explain its mechanism?

Selenium WebDriver is a browser automation framework that accepts commands and sends them to a browser. It is implemented through a browser-specific driver. It controls the browser by directly communicating with it. Selenium WebDriver supports Java, C#, PHP, Python, Perl, Ruby.

Why is WebDriver an interface?

WebDriver is an interface provided by Selenium WebDriver. As we know that interfaces in Java are the collection of constants and abstract methods(methods without any implementation). The WebDriver interface serves as a contract that each browser-specific implementation like ChromeDriver, FireFoxDriver must follow.

What is the main transport mechanism used by WebDriver?
