The operating system provides an interface between an application program and
the computer hardware, so that an application program can interact with the
hardware only by obeying rules and procedures programmed into the operating
system. The operating system is also a set of ...

A computing platform is the environment in which a piece of software is executed.
It may be the hardware or the operating system (OS), even a web browser or
other underlying software, as long as the program code is executed in it.
Computing platforms have different abstraction levels, including a computer
Since the end of the 20th century, supercomputer operating systems have
undergone major transformations, as fundamental changes have occurred in
supercomputer architecture. While early operating systems were custom tailored
to each supercomputer to gain speed, the trend has been moving away from in-
The operating system (prominent examples being Microsoft Windows, macOS
and Linux), allows the parts of a computer to work together by performing tasks
like transferring data between memory and disks or rendering output onto a
Microsoft Windows, or simply Windows, is a group of several graphical operating
system families, all of which are developed, marketed, and sold by Microsoft.
Each family caters to a certain sector of the computing industry. Active Windows
families include Windows NT and Windows Embedded; these may encompass ...

In computer software, an operating environment or integrated applications
environment is the environment in which users run application software. The
environment consists of a user interface provided by an applications manager
and usually an application programming interface (API) to the applications
Most computers are sold with a pre-installed operating system (OS); some users
replace that OS with a different one due to personal preference, or install another
OS alongside it and use both. Conversely, sales underestimate usage by not
counting unauthorized copies.
Software compatibility can refer to the compatibility that a particular software has
running on a particular CPU architecture such as Intel or PowerPC. Software
compatibility can also refer to ability for the software to run on a particular
operating system. Very rarely is a compiled software ...
Thus, on a standard personal computer an operating system handles signals
from input and output devices, manages memory usage and controls peripherals.
Therefore, the operating system is the most important program a computer must
run. An operating system has two jobs: to ...
The operating system is the computer's most important piece of software. It
manages the hardware resources, determines which programs are compatible
with the system and executes those programs when ...
Microsoft's first operating system, MDOS/MIDAS, was designed along many of the
PDP-11 features, but for microprocessor based systems. MS-DOS, or PC DOS
when supplied by IBM, was based originally on CP/M-80. Each of these
machines had a small boot program in ROM which ...
Apple first launched its classic Mac OS in 1984, bundled with its Macintosh
personal computer. Apple moved to a nanokernel design in Mac OS 8.6. Against
this, the modern macOS (originally named Mac OS X) is based on Darwin, which
uses a hybrid kernel called XNU, which was created ...
The term network operating system is used to refer to two rather different
concepts: A specialized operating system for a network device such as a router,
switch or firewall. An operating system oriented to computer networking, to allow
shared file and printer access among multiple computers in a network, to enable
