Ultrabook
The Ultrabook is a type of laptop, trademarked by Intel, that falls into the thin and lightweight laptop category (considered ultraportable laptops). It is Intel's attempt to compete against the tablet computers running ARM (Advanced RISC Machine) processors. The Ultrabooks use Sandy Bridge, Ivy Bridge, and Haswell processor architecture developed by Intel. The picture shows an ASUS Zenbook, an example of an Ultrabook.
