MACINTOSH
0 The Macintosh marketed as Mac, is a line of
personal computers (PCs) designed,
developed, and marketed by Apple Inc. It is
targeted mainly at the home, education, and
creative professional markets. Steve Jobs
introduced the Macintosh 128K on January 24,
1984. This was the first mass-market personal
computer featuring a graphical user interface
and mouse.
WINDOWS
0 Windows 8 is a personal computer
operating system developed by
Microsoft as part of Windows NT family
of operating systems. Development of
Windows 8 started before the release of
its predecessor, Windows 7, in 2009.
LINUX
0 Linux is a Unix-like and POSIX-compliant
computer operating system assembled under
the model of free and open source software
development and distribution. The defining
component of Linux is the Linux kernel, an
operating system kernel first released on 5
October 1991 by Linus Torvalds. Linux was
originally developed as a free operating
system for Intel x86-based personal
computers.
UNIX
0 Unix is a multitasking, multi-user computer operating
system that exists in many variants. The original Unix
was developed at Bell Labs research center by Ken
Thompson, Dennis Ritchie, and others. From the
power user's or programmer's perspective, Unix
systems are characterized by a modular design that is
sometimes called the "Unix philosophy," meaning the
OS provides a set of simple tools that each perform a
limited, well-defined function, with a unified file
system as the main means of communication.
IOS7
0 iOS 7 is the seventh major release of the iOS mobile
operating system designed by Apple Inc as the
successor to iOS 6. It was announced at the company's
Worldwide Developers Conference (WWDC) on June
10, 2013, and was released on September 18, 2013.[2]
iOS 7 includes a redesigned user interface and
numerous functionality changes. The design of iOS 7's
new elements was led by JonyIve, Apple's Senior Vice
President of Design. As of December 2013, iOS 7 has
been installed on 78% of supported devices.
