A Chromebook is a computer running the Google Chrome OS that began shipping June 15, 2011. The Chromebook is different from other laptops because they require the Internet, are cheaper, and run almost everything from the cloud.
The Google Chrome OS is a Linux-based operating system developed by Google to work exclusively with online web applications. After its initial development on July 7, 2009, Google made the operating system an open source project under the name Chromium on November 19, 2009. The Chrome OS can only be run on a computer that is designed for Chrome OS and cannot be used on computers designed for Windows or other operating systems.
