1. Independent Operating Systems Explained
•An Operating System is software made up of data and
programs that is a common feature on most computers and
completes a variety of functions such as managing computer
hardware resources as well as providing common services to
assist with the execution of the operations of various
application software (computer software which is designed for
the express purpose of helping the user to perform single or
multiple related tasks, such as media players, office suites and
accounting software). For hardware functions (such as memory
allocation and input and output), the operating system acts as a
kind of ‘middleman’ between the computer programs and the
application software.

2. Independent Operating Systems Explained
•Operating systems are quite probably the most important
examples of system software that is present in a computer
system since without an operating system, it would be
impossible for a user to run an application program on their
computer (that is of course unless the application is ‘self-
booting’ and therefore would not require the assistance of an
operating system). It is for this reason that operating systems
are found on almost every device that contains any form of
computer, ranging from top of the range supercomputers and
web servers everyday technological devices, such as video
game consoles and even mobile phones.

3. Independent Operating Systems Explained
Components of independent operating systems include the
Kernel (the most important of all components of an operating
system) which acts as a bridge between application software
and the actual data processing that is conducted at hardware
level. Responsibilities of this component include managing the
resources of the system (the managing of the communication
between the hardware and the software components).
Interrupts (asynchronous signals which indicate the need for
attention or indicating a synchronous event in a piece of
software that needs a change in execution) are another
essential part of operating systems, as is multitasking (the
running of multiple independent computer programs on the
same computer).

4. Independent Operating Systems Explained
•It is often the case that application software is written to be
used on only one single independent operating system (and
sometime even for one specific piece of hardware) and as a
result it has become possible in recent years for computers to
support a number of different independent operating systems.
The cost in supporting a number of diverse operating systems
can be avoided by the user instead writing applications against
software platforms (a crucial element in the development of
software) such as Java.
