In a nutshell, a Chromebook is a mobile device for using Chrome, a web browser. It is equipped with a dedicated OS called Chrome OS and is designed to operate comfortably with the latest version of Chrome. When it was born in the United States 10 years ago, it had a lineup of only clamshell notebooks, but recently there are more variations such as a tablet with a kickstand and a 2in1 display with a 360-degree rotation. Since the basic design is not much different from that of a PC for Windows, there is an advantage that the manufacturer can commercialize the device developed for Windows without making major changes.
One of the things that makes a Chromebook different from a Windows PC is the keyboard layout. Instead of function keys, Chromebooks have keys that correspond to functions such as [Forward], [Back], and [Update] of the Web browser. For example, on a Windows PC, when using Edge or Chrome, you can use the F5 key or Ctrl + F5 key to [Refresh] the page, but on a Chromebook, you can easily execute it by pressing the unique update key. In addition, a "search key" that is not available on Windows PCs is assigned. For Chromebooks, it seems to be called "Everything button". Not only can you search the Web, but you can also find files and apps. There is a presence like a keyboard designed by Google for search.
By the way, the operation of Japanese input is closer to Mac than Windows PC. Use the [Alphanum] and [Kana] keys on the left and right of the space bar to switch between Japanese and alphanum characters. Recently, Microsoft has adopted the same key layout on some Surface models, but future Japanese keyboards including Mac will use these [alphanumerical] and [kana] keys as standard. it is conceivable that. Except for these small keyboard differences, the Chromebook is a Chrome-only device that can be easily switched from a Windows PC.
