Chrome OS is developed by which company?

Chrome OS is a lightweight operating system that is specifically designed and developed by Google. It is primarily built for web applications and utilizes the Google Chrome web browser as its main interface. This operating system is prevalent in Chromebooks, which are laptop devices optimized for speed and efficiency, often used in education and business environments.

The operating system is closely integrated with Google's ecosystem, allowing users to easily access applications and services from the cloud. This focus on cloud computing and simplicity distinguishes Chrome OS from traditional operating systems that require more complex installations and configurations.

In the context of the other options, it's essential to note that Apple is known for macOS and iOS, Microsoft develops Windows and related software products, while the Linux Foundation supports the development of the Linux kernel and associated projects but does not develop Chrome OS itself. Therefore, understanding that Chrome OS is a proprietary system from Google solidifies the connection between the operating system and its creator.
