Was developed by Apple Inc. The OS was introduced in 1984 to run the company's
Macintosh line of personal computers (PCs). The Macintosh signaled the era of
graphical user interface (GUI) systems, which prompted the creation of the
Windows OS from Microsoft Corporation. This OS was heavily marketed by its
intuitive ease of use. The Mac OS was unlike most other contemporary PCs
because they focused on agraphically based design where users moved a mouse
pointer to visually navigate the FInder - a series of virtual folders and files
, represented by icons. Most computer OS eventually adopted this GUI, including
an agreement in the 1980s that allowed Microsoft to use certain aspects of the
Mac OS in early versions of Windows.


Windows OS, computer operating system was developed by Microsoft Corporation to
run personal computers. The first version of Windows, released in 1985, was
simply a GUI offered as an extension of Microsoft's existing disk operating
system, or MS-DOS. Windows for the first time allowed DOS users to visually
navigate a virtual desktop, opening graphical "windows" displaying the contents
of electronic folders and files with the click of a mouse button, rather than
typing commands and directory paths at a text prompt. Later versions introduced
greater functionality, including native Windows File Manager, Program Manager,
and Print Manager programs, and a more dynamic interface. Microsoft also
developed specialized Windows packages, including the networkable Windows for
Workgroups and the high-powered Windows NT, aimed at businesses.


In 1991, while studying computer science at University of Helsinki, Linus
Torvalds begana project that later became the Linux kernel. He wrote the
program specifically for the hardware he was using and independent of an
operating system because he wanted to use the functions of his new PC with an
80386 processor. Development was done on MINIX using the GNU C Compiler. The
GNU C Compiler is still the main choice for compiling Linux today, but can be
built with other compilers, such as the Intel C Compiler.
