Macbook

The MacBook was a brand of Macintosh notebook computers manufactured by Apple Inc. from early 2006 to late 2011. It replaced the iBook series and 12-inchPowerBook series of notebooks as a part of the Apple–Intel transition from PowerPC. Positioned as the low end of the MacBook family, the Apple MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh in history, and according to the sales-research organization NPD Group in October 2008, the mid-range model of the MacBook was the single best-selling laptop of any brand in US retail stores for the preceding five months.

There have been three separate designs of the MacBook: the original model used a combination of polycarbonate and fiberglass casing that was modeled after the iBook G4. The second type, introduced in October 2008 alongside the 15-inch MacBook Pro, used a similar unibody aluminum casing to the 15-inch Pro, and was updated and rebranded as the 13-inch MacBook Pro at the 2009 Apple Worldwide Developers Conference in June 2009. A third design, introduced in October 2009, used a unibody polycarbonate shell as aluminum is now reserved for the higher-end MacBook Pro. On July 20, 2011, the MacBook was quietly discontinued for consumer purchase in favor of the new MacBook Air. Apple continued to sell the MacBook to educational institutions until February 2012. The MacBook has effectively been superseded by the MacBook Air.

Embedded System

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computingconstraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.

Embedded systems contain processing cores that are either microcontrollers or digital signal processors (DSP).

A processor is an important unit in the embedded system hardware. It is the heart of the embedded system.

The key characteristic, however, is being dedicated to handle a particular task. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.

Physically, embedded systems range from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights,factory controllers, and largely complex systems like hybrid vehicles, MRI, and avionics. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or encl

osure.

Microsoft Office 2010

Microsoft Office 2010 (also called Office 2010 and Office 14) is a version of the Microsoft Office productivity suite for Microsoft Windows,and the successor to Microsoft Office 2007. Office 2010 includes extended file format support, user interface updates,and a changed user experience. A 64-bit version of Office 2010 is available, although not for Windows XP or Windows Server 2003.

On April 15, 2010, Office 2010 was released to manufacturing. The suite became available for retail and online purchase on June 15, 2010. Office 2010 is the first version to require product activation for volume licensing editions. In Office 2010, every application features ribbons in user interface.

Office 2010 marks the debut of Office Web Apps, free online versions of Word, Excel, PowerPoint, and OneNote, which work in web browsers. Office Starter 2010, a new edition of Office, replaced the low-end home productivity software, Microsoft Works. Microsoft's update to its mobile productivity suite, Office Mobile 2010, is released for Windows Phones running Windows Mobile 6.5 and Windows Phone 7.

As of December 31, 2011, almost 200 million licenses of Office 2010 have been sold.

Office 2010 is the last version of Microsoft Office with support for Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008.
