SOFTWARE:
DEFINITION:
“A piece of software is a computer program which has been written to carry out a
particular task.”
“A set of instruction to solve a particular problem”
Without software the hardware that is used to build a computer system would not be very useful.
A software program contains the instructions that the computer must follow to carry out the task.
Sometimes more than one program is required to complete a task. When this is the case the
group of programs which together complete the task are known as a software package.
Software programs are originally produced by computer programmers who will write the
instructions that form the program in a programming language.
Example pieces of software are:
A word processor.
A multimedia encyclopedia.
A spreadsheet.
