An introduction of OS.
Modern general-purpose computers, including personal computers
and mainframes, have an operating system to run other programs, such as
application software. Examples of operating systems for personal computers
include Microsoft Windows, Mac OS (and Darwin), Unix, and Linux.
The lowest level of any operating system is its kernel. This is
the first layer of software loaded into memory when a system boots or starts
up. The kernel provides access to various common core services to all other
system and application programs.
These services include, but are
not limited to: disk access, memory management, task scheduling,
and access to other hardware
devices.
As well as the kernel, an operating system is often distributed
with tools for programs to display and manage a graphical user interface
(although Windows and the Macintosh have these
tools built into the operating system), as well as utility
programs for tasks such as managing files and configuring the operating system.
They are also often distributed with application software that does not relate
directly to the operating system's core function, but which the operating
system distributor finds advantageous to supply with the operating system.
The delineation between the operating system and application
software is not precise, and is occasionally subject to controversy. From
commercial or legal points of view, the delineation can depend on the contexts
of the interests involved. For example, one of the key questions in the United
States Microsoft antitrust trial was
whether Microsoft's web browser was part of its
operating system, or whether it was a separable piece of
application software.
Like the term "operating system" itself, the question
of what exactly should form the "kernel" is subject to some
controversy, with debates over whether things like file systems should be
included in the kernel. Various camps advocate microkernel’s, monolithic
kernels, and so on.
Operating systems are used on most, but not all, computer
systems. The simplest computers, including the smallest embedded systems and
many of the first computers did not have operating systems. Instead, they
relied on the application programs to manage the minimal hardware themselves,
perhaps with the aid of libraries developed for the purpose.
Commercially-supplied operating systems are present on virtually all modern
devices described as computers, from personal computers to mainframes, as well
as mobile computers such as PDAs and mobile phones.
