Types of software

1. TYPES OF SOFTWARE

2. WHAT IS SOFTWARE?
WHAT IS HARDWARE?

3. Computer software, or just software, is
any set of machine-readable instructions
that directs a computer's processor to
perform specific operations. The term is
used to contrast with computer
hardware, the physical objects
(processor and related devices) that
carry out the instructions.

4. Computer software is a set of programs,
procedures, functions, associated data and/or
its documentation, if any. Program software
performs the function of the program it
implements, either by directly providing
instructions to the digital electronics or by
serving as an input to another piece of software.
Software is also sometimes used in a more
narrow sense, meaning application software
only.

5. TYPES OF SOFTWARE

6. SYSTEM SOFTWARE
is computer software designed to operate
the computer hardware, to provide basic
functionality, and to provide a platform for
running application software. System
software includes device drivers, operating
systems, servers, utilities, and window
systems.

7. UTILITY SOFTWARE
is software such as anti-virus
software, firewalls, disk
defragmenters and so on which
helps to maintain and protect the
computer system but does not
directly interface with the hardware.

8. APPLICATION SOFTWARE
•and scripts were historically defined as all the
software that uses the computer system to
perform useful work (or entertainment
functions) beyond the basic operation of the
computer itself. However, in practice the
distinction between system software and
application software is often blurred due to
bundling of useful applications with the
operating system.

9. •Application software includes
desktop applications such as
web browsers and Microsoft
Office, as well as smartphone
and tablet applications (called
"apps").

10. Javascript scripts are pieces of software
traditionally embedded in web pages that are run
directly inside the web browser when a web page
is loaded, without the need for a web browser
plugin. Software written in other programming
languages can also be run within the web browser
if the software is either translated into Javascript,
or if a web browser plugin that supports that
language is installed; the most common example
of the latter is ActionScript scripts, which are
supported by the Adobe Flash plugin.

11. EMBEDDED SOFTWARE
resides as firmware within embedded
systems, devices dedicated to a single use or
a few uses such as cars and televisions
(although some embedded devices such as
wireless chipsets can themselves be part of
an ordinary, non-embedded computer
system such as a PC or smartphone)
