SPECIFICATION OF LATEST OPERATING SYSTEM

The operating system is the software that controls the operation of a computer and directs the processing of programs. When you first turn on a new computer the desktop, files, and folders that appear are a function of your operating system.

The difference between the “old” operating systems and these new operating systems is like the difference between a 5-year-old GE stove and one of this year’s professional-quality models built to rival commercial equivalents. According to a recent article in Time Magazine, the kitchen has become the new family headquarters and “as any corporate boss can tell you, headquarters tend to get all the bells and whistles.” (Saporito, 2002)

Windows 7 sold well during the 2009 holiday season, and the results are showing up, not only in sheer revenue, but in the OS market share numbers as well. Nevertheless, in December 2009, Linux was the only operating system to show positive percentage growth in market share.

Between November and December 2009, Windows market share dropped 0.31 percentage points (from 92.52 percent to 92.21 percent), Mac OS dipped 0.01 percentage points (from 5.12 percent to 5.11 percent), and Linux edged forward 0.02 percentage points (from 1.00 percent to 1.02 percent).

Strong sales from Windows 7 and Snow Leopard were not enough to stop both Windows overall and Mac OS overall from dropping. When putting this into perspective across the whole year, though, we see that Windows was actually sliding steadily throughout 2009 (93.66 percent in January 2009), while both Mac OS (4.71 percent in January 2009) and Linux (0.90 percent in January 2009) have been gaining.

You can see the market share pie for December 2009, according to Net Applications, at the top of this post. The graph directly above this paragraph shows how things at Ars are different from those elsewhere, but the differences aren't as significant when it comes to the browser market: our Mac OS share is more than five times greater than the rest of the world, while Linux is six times more. Nevertheless, more than half of our users are on Windows.

Even if Windows is slowly losing share, Windows 7 is doing phenomenally well. Above, you can see how quickly the OS has been gaining share in its first few months compared to Windows Vista's first few months.

While Vista was at 0.93 percent after a month, Windows 7 was at 4.00 percent; when Vista jumped to 2.04 percent after two months, Windows 7 hit 5.71 percent.

There are many reasons for this, including the fact that Vista had to compete with XP, which was on the market for an abnormally long time. Furthermore, Windows 7 arrived in time for holiday sales, while Vista did not. In addition, Windows 7 had a very successful beta program, both private and public. Most importantly though, Microsoft managed to generate the kind of hype around Windows 7 that it hasn't generated around any of its operating systems in years.

In terms of OS versions, Windows saw the following changes between November and December: Windows XP dropped 1.28 percentage points (from 69.05 percent to 67.77 percent), Windows Vista dropped 0.68 percentage points (from 18.55 percent to 17.87 percent), and Windows 7 gained 1.71 percentage points (from 4.00 percent to 5.71 percent), meaning it has passed all versions of Mac OS. Speaking of which, Mac OS saw the following progress: version 10.4 dipped 0.04 percentage points (from 0.84 percent to 0.80 percent), version 10.5 dipped 0.14 percentage points (from 2.61 percent to 2.47 percent), and version 10.6 moved up 0.22 percentage points (from 1.38 percent to 1.60 percent).

Taking the historical perspective, we can see that Windows Vista and Windows 7 together have just over a third of Windows XP's market share, while Mac OS 10.5 and 10.6 together have more than five times the market share of Mac OS 10.4.

Before the end of 2010, we're expecting to see Windows 7 pass Windows Vista, Windows XP to drop below the 50 percent mark, and Mac OS X 10.6 to pass 10.5 and 10.4 combined.

LATEST OS IN MICROSOFT WINDOWS

Microsoft has taken two parallel routes in its operating systems. One route has been for the home user and the other has been for the professional IT user. The dual routes have generally led to home versions having greater multimedia support and less functionality in networking and security, and professional versions having inferior multimedia support and better networking and security.[citation needed]

The first version of Microsoft Windows, version 1.0, released in November 1985, lacked a degree of functionality and achieved little popularity, and was to compete with Apple’s own operating system.[citation needed] Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. Microsoft Windows version 2.0 was released in November 1987 and was slightly more popular than its predecessor. Windows 2.03 (release date January 1988) had changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights.[10][11]

Microsoft Windows version 3.0, released in 1990, was the first Microsoft Windows version to achieve broad commercial success, selling 2 million copies in the first six months.[12][13] It featured improvements to the user interface and to multitasking capabilities. It received a facelift in Windows 3.1, made generally available on March 1, 1992. Windows 3.1 support ended on December 31, 2001.[14]

In July 1993, Microsoft released Windows NT based on a new kernel. Windows NT 3.1 was the first release of Windows NT. NT was considered to be the professional OS and was the first Windows version to utilize preemptive multitasking.[citation needed] Windows NT would later be retooled to also function as a home operating system, with Windows XP.

On August 24, 1995, Microsoft released Windows 95, a new, and major, consumer version that made further changes to the user interface, and also used preemptive multitasking. Windows 95 was designed to replace not only Windows 3.1, but also Windows for Workgroups, and MS-DOS. It was also the first Windows operating system to use Plug and Play capabilities. The changes Windows 95 brought to the desktop were revolutionary, as opposed to evolutionary, such as those in Windows 98 and Windows Me. Mainstream support for Windows 95 ended on December 31, 2000 and extended support for Windows 95 ended on December 31, 2001.[15]

The next in the consumer line was Microsoft Windows 98 released on June 25, 1998. It was followed with the release of Windows 98 Second Edition (Windows 98 SE) in 1999. Mainstream support for Windows 98 ended on June 30, 2002 and extended support for Windows 98 ended on July 11, 2006.[16]

As part of its "professional" line, Microsoft released Windows 2000 in February 2000. During 2004 part of the Source Code for Windows 2000 was leaked onto the Internet. This was bad for Microsoft as the same kernel used in Windows 2000 was used in Windows XP. The consumer version following Windows 98 was Windows Me (Windows Millennium Edition). Released in September 2000, Windows Me implemented a number of new technologies for Microsoft: most notably publicized was "Universal Plug and Play". Windows Me was heavily criticized due to slowness, freezes and hardware problems.

In October 2001, Microsoft released Windows XP, a version built on the Windows NT kernel that also retained the consumer-oriented usability of Windows 95 and its successors. This new version was widely praised in computer magazines.[17] It shipped in two distinct editions, "Home" and "Professional", the former lacking many of the superior security and networking features of the Professional edition. Additionally, the first "Media Center" edition was released in 2002,[18] with an emphasis on support for DVD and TV functionality including program recording and a remote control. Mainstream support for Windows XP ended on April 14, 2009. Extended support will continue until April 8, 2014.[19]

In April 2003, Windows Server 2003 was introduced, replacing the Windows 2000 line of server products with a number of new features and a strong focus on security; this was followed in December 2005 by Windows Server 2003 R2.

On January 30, 2007, Microsoft released Windows Vista. It contains a number of new features, from a redesigned shell and user interface to significant technical changes, with a particular focus on security features. It is available in a number of different editions, and has been subject to some criticism.

On October 22, 2009, Microsoft released Windows 7. Unlike its predecessor, Windows Vista, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware which Windows Vista was not at the time.[20] Windows 7 has multi-touch support, a redesigned Windows shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup,[21] and performance improvements.
