Major Operating Systems
recent version of Windows is Windows 10. Net Applications estimates that overall market share
of Windows as of 2015 is Windows 10 at 0.1 percent, Windows 8.1 at 11.2 percent, Windows
8 at 3.5 percent, Windows 7 at 58.4 percent, Windows Vista at 2.0 percent, and Windows XP at
20
16.0 percent. It’s interesting to note that Microsoft dropped support for Windows XP in 2014
despite the fact that it is still more popular than Windows Vista, Windows 8, Windows 8.1, and
Windows 10.
Windows 8 was a major rewrite of prior versions. Windows 8 was distinguished by what
21
Microsoft calls modern-style applications. These applications, now carried over into Windows
10, are touch-screen oriented and provide context-sensitive, pop-up menus. They can also be used
with a mouse and keyboard. Microsoft claims that modern-style applications work just as well on
portable, mobile devices, such as tablet computers, as they do on desktop computers. One key fea-
ture of modern-style applications is the minimization of menu bars, status lines, and other visual
overhead. Figure 4-11 shows an example of a modern-style version of searching for images in
Windows Explorer.
Apple Computer, Inc., developed its own operating system for the Macintosh, Mac OS. The
current version is Mac OS X El Capitan. Apple touts it as the world’s most advanced desktop
operating system, and, until Windows 8, it was without doubt. Windows 10 now gives it a run for
the money in terms of that title.
