Computer Software are programs that tell the computer what to do.
World first calculation machine
World first calculation machine
The Abacus ( 1623 )
◦ The first computing aid that were used to help them in their computation. (John Napier )
The Difference Engine◦ An automatic, mechanical calculator designed to
tabulate polynomial functions. ◦ By 1822 the English mathematician Charles Babbage
who is considered as Father of the Computer today was proposing a steam driven calculating machine the size of a room
