2. Computer software.
Software, or program,
enables a computer to
perform specific tasks, as
opposed to the physical
components of the system
(hardware).
4. Operating system
• An operating system (OS) is a computer program that
manages the hardware and software resources of a
computer.
• At the foundation of all system software, an operating
system performs basic tasks such as controlling and
allocating memory, prioritizing system requests,
controlling input and output devices, facilitating
networking, and managing files.
• It also may provide a graphical user interface for higher
level functions. It forms a platform for other software
5. • Example :
1. Linux
2. Microsoft Window Vista
3. Red Hat
6. Utilities software
• Utility software (also known as service program,
service routine, tool, or utility routine) is a type of
computer software.
• It is specifically designed to help manage and tune the
computer hardware, operating system or application
software, and perform a single task or a small range of
tasks; as opposed to application software which tend to
be software suites.
• Utility software has long been integrated into most major
operating systems.
8. Application Software
• Application software is a subclass of computer
software that employs the capabilities of a computer
directly to a task that the user wishes to perform.
• This should be contrasted with system software which is
involved in integrating a computer's various capabilities,
but typically does not directly apply them in the
performance of tasks that benefit the user.
