2. What is Software?
Software means computer instructions or data. Anything that can be stored
electronically is software , in contrast to storage devices and display devices which
are called software
Software means set of programme where programs are set by step logical
meaningful instruction given to a computer. Software consists of programme &
associated with document.

3. • Software of a computer system is intangible rather than physical. It is the term
used for any type of program. Software consists of statements which instruct a
computer to perform the required task. Without software a computer is simply a
mass of electronic component.
• Mainly hardware does the computing work and software run the computer.
Actually it is the giddying part of the computer.
• So , the term software refers to the set of computer programs , procedures &
associated documents ( flowcharts, manuals etc.) which describe the programme
and how they to be used. To be precise software means a collection of programs
whose objective is to enhance the capabilities of the hardware.

4. Relationship between software & hardware
• In order for a computer to produce useful output , its hardware & software
must work together . Nothing useful can be be done with the computer hardware
on its own & software can’t be utilized without supporting hardware . So , there
is a close connection between software & hardware.
• Some points regarding this are as follows :
 Both hardware & software are necessary for a computer to do useful job. Both
are complementary to each other.
 The same hardware can be loaded with different software to make a computer
system perform different types of job , just as different songs can be played using
the same cassette player.

5. Purposes of software.
The purposes of software are as follows :
 Computer programme is used for automated system.
Developing the system.
Scientific research.
Developing of programming language.
