software
Software is a set
of instruction that when executed provide desired features, function and data
structure that enable the programs to adequately manipulate information. Software is logically different than
the physical system element.
Software’s are
developed for particular customers. Software is not just the program but
also associated documentation configuration of data that is needed to make
programs operated correctly.
A software
system usually consists of number of different programs, configuration files
which are used to set up these programs, system documentation which describe
the structure of the system and user documentation which describe the structure
of system. User documentation explains how to use software and websites
for user to download recent product information.
Software's are engineered, these are not manufactured. Software's are developed by using software engineering
techniques. Software engineering techniques lead them to produce best product. Software is
implemented in hardware.
There are some similarities between software development and
hardware manufacturing. The software development and hardware manufacturing are
two activities and are fundamentally different. In software and hardware high
quality is achieved through good design and efficient engineering strategy, but
in the manufacturing phase for hardware can introduce quality problems that are
non existent.
