The Google Pixel Slate Chromebook has the sort of spec you'd expect from a laptop, but it looks and feels like a tablet. And let's not forget it's a Chromebook too, so when you start it up there's no waiting around, and everything you need loads up in seconds. The Pixel Slate also has a beautiful Quad HD screen (that's twice as good as Full HD) so every app, game and photo will be crisp and detailed. And if you do want to type something up like on a standard laptop, the Google Pixel Slate Keyboard (sold separately) is all you need. NOTE: THIS IS FOR THE TABLET ONLY. KEYBOARD AND STYLUS PEN ARE NOT INCLUDED.

Every VoIP phone contains one or more codecs, and during call establishment, they share their lists of supported codecs. One phone, for example, may say “Hey stranger, I can support codecs A, B, or C”, and the other one will respond “Nice to meet you, I can support codecs “B, C, or D.” At this point, both phones recognize that they could converse in either B or C (this process is can easily be compared to two multilingual strangers meeting on the street, figuring out what languages they share, then deciding which of the shared languages to proceed in).
