Why Programs?

Computers can do many different jobs because they are

programmable

– Documentation (Word, Excel, Pdf, ppt)

– Navigation (Maps)

– Entertainment (iPods, Social Media, Movie player)

Computer Systems

▪ Hardware

▪ Software

Software

Programs are commonly referred to as software. Software is

essential to a computer because without software, a

computer can do nothing.

▪ System Software (Operating Systems, Utility Programs,

Software development tools)

▪ Application Software (MS office, Games, Media Players)

What is Computer Programming

▪ Computer programming is the process of designing and

building an executable computer program for

accomplishing a specific computing task.

▪ Computer programming is both an art and a science.
