Windows 7

Windows 7 (codenamed Vienna, formerly Blackcomb) is a personal computer operating system developed by Microsoft. It is a part of the Windows NT family of operating systems. Windows 7 was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time.

Windows 7 was primarily intended to be an incremental upgrade to the operating system intending to address Windows Vista's poor critical reception while maintaining hardware and software compatibility. Windows 7 continued improvements on Windows Aero (the user interface introduced in Windows Vista) with the addition of a redesigned taskbar that allows applications to be "pinned" to it, and new window management features. Other new features were added to the operating system, including libraries, the new file sharing system HomeGroup, and support for multitouch input. A new "Action Center" interface was also added to provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. Windows 7 also shipped with updated versions of several stock applications, including Internet Explorer 8, Windows Media Player, and Windows Media Center.

Windows 7 editions

Windows 7, a major release of the Microsoft Windows operating system, was available in six different editions: Starter, Home Basic, Home Premium, Professional, Enterprise and Ultimate. Only Home Premium, Professional, and Ultimate were widely available at retailers. The other editions focus on other markets, such as the developing world or enterprise use. All editions support 32-bit IA-32 CPUs and all editions except Starter support 64-bit x64 CPUs. 64-bit installation media is not included in Home-Basic edition packages, but can be obtained separately from Microsoft.

According to Microsoft, the features for all editions of Windows 7 are stored on the machine, regardless of which edition is in use. Users who wish to upgrade to an edition of Windows 7 with more features can then use Windows Anytime Upgrade to purchase the upgrade and to unlock the features of those editions. Microsoft announced Windows 7 pricing information for some editions on June 25, 2009, and Windows Anytime Upgrade and Family Pack pricing on July 31, 2009.

Microsoft Windows

Microsoft Windows (or simply Windows) is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry. Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact (Windows CE) or Windows Server. Defunct Windows families include Windows 9x and Windows Mobile.

Microsoft introduced an operating environment named Windows on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984. However, since 2012, because of the massive growth of smartphones, Windows sells less than Android, which became the most popular operating system in 2014, when counting all of the computing platforms each operating system runs on; in 2014, the number of Windows devices sold were less than 25% of Android devices sold. However, comparisons across different markets are not fully relevant; and for personal computers, Windows is still the most popular operating system.

Dell Latitude

Latitude is Dell's business laptop brand, designed and manufactured mainly by Compal and Quanta. The Latitude competes with the ThinkPad series from Lenovo (formerly IBM ThinkPad series) and Travelmate series from Acer.

Overview and product type

The Dell Latitude is a laptop family from Dell Computers, intended for business use. By contrast, the Dell Inspiron is aimed at the consumer market and its specifications change regularly. Whereas Inspiron may change vendors or components several times over the course of a single model, the Latitude line generally retains identical components throughout its production. This design is intended to simplify maintenance and support tasks for large corporations, allowing components to be easily swapped between models.

Dell Latitude computers are also built to Dell's RoadReady specification which includes a durable magnesium-alloy casing (though budget version D500/E5000-series Latitudes are mainly plastic), internal metal frames and Strike Zone shock protection in case the computer is dropped or suffers a severe impact. Many models also feature free-fall sensors or solid-state drives. Latitude models are also considered more durable and higher quality than the Inspiron line, and even above the premium Studio and XPS models. The Ultraportable 4-series and mainstream 6-series Latitude models have 3 year support, as opposed to the 1 year warranty on other models. The essential Latitudes retain the 1 year warranty of other products. But, this results in a price several hundreds of dollars higher compared to the consumer models.

Professional

A professional is a member of a profession or any person who earns their living from a specified activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform the role of that profession. In addition, most professionals are subject to strict codes of conduct enshrining rigorous ethical and moral obligations. Professional standards of practice and ethics for a particular field are typically agreed upon and maintained through widely recognized professional associations. Some definitions of "professional" limit this term to those professions that serve some important aspect of public interest and the general good of society.

In some cultures, the term is used as shorthand to describe a particular social stratum of well-educated workers who enjoy considerable work autonomy and who are commonly engaged in creative and intellectually challenging work.

Trades

In narrow usage, not all expertise is considered a profession. Although sometimes incorrectly referred to as professions, occupations such as skilled construction and maintenance work are more generally thought of as trades or crafts. The completion of an apprenticeship is generally associated with skilled labour, or trades such as carpenter, electrician, mason, painter, plumber and other similar occupations. A related distinction would be that a professional does mainly mental work, as opposed to engaging in physical work.
