Samsung Chromebook Series 5 Part.III

This excellent battery life allows forgetting the charger at home, and this is fortunate: it is not the most compact in its class. You end up using this as using a Chromebook iPad: he can spend several days away from a wall outlet and use a few hours a day, always ready with its wake very fast. We return again to the lightness of Chrome OS and it raises the question what does this processor double heart, would he not had to sacrifice a little raw power (for even longer battery life), and example the graphics muscle (useful for acceleration and video decompression)?

The lightness comes from its Chrome OS architecture: it is based on a Linux (Debian) stripped of all its dross. The sequence of starting a traditional OS is here reduced to its simplest terms: in 8 seconds, the kernel is loaded, the material started (no need for profiling, while side firmware is loaded), and the user can then identify. He is faced with a browser, Chrome.

The first start Chrome OS takes a few minutes and cannot be done without internet connection. On leaving the board, it is likely that your Chromebook will need an update: Some system components are user side, but more importantly, the browser and applications are in the cloud.

The key is your Google account: it allows you to connect, and also serves as a keychain. Passwords, history, bookmarks, applications, and even state of the machine, everything is linked to your Google account, so you can find your session by logging on to a new machine or the machine ... at another. The Chromebook indeed have a guest mode (off) allowing a friend or colleague to connect to the session without disturbing the administrator - we find here the logic of the old couple client / mainframe. We like ... or not.
