A set
of rules that provides a way of telling a computer what operations to perform
is called a programming language.
A program is a
set of step-by-step instructions that directs the computer to do the tasks you
want it to do and produce the results you want. Programmer’s
job is to convert problem solutions into instructions
for the computer.

Flowchart
is a type of diagram that represents an
algorithm, workflow or process, showing the steps as boxes of various kinds,
and their order by connecting them with arrows.
a picture of the separate steps of a
process in sequential order.

Basic Procedure
}Define
the process to be diagrammed. Write its title at the top of the work surface.
}Discuss
and decide on the boundaries of your process: Where or when does the process
start? Where or when does it end? Discuss and decide on the level of detail to
be included in the diagram.
}Brainstorm
the activities that take place. Write each on a card or sticky note. Sequence
is not important at this point, although thinking in sequence may help people
remember all the steps.
Algorithm

or formula for solving a problem.
-a step-by-step procedure for solving a problem.
