The MacBook is a brand of notebook computers manufactured by Apple Inc. from May 2006 to February 2012, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh ever.
From Wikipedia, the free encyclopedia. Ultrabook was created as a specification and trademarked brand by Intel for a class of high-end subnotebooks designed to feature reduced bulk without compromising battery life. They used low-power Intel Core processors, solid-state drives, and unibody chassis to help meet these criteria. Due to their limited size, Ultrabooks typically omitted common laptop features such as optical disc drives and Ethernet ports. Ultrabook is a portmanteau of words ultraportable and notebook.
