Input, Process, Output, Storage
Entering data into the
computer system (mouse, keyboard, scanner)
Input
Data entered is processed and undergo
operations (checking accuracy and mathematical manipulations)
Process
provides data to the user (printer, monitor, speakers)
Output
Stores data for later use.
Storage
is a computer software designed to perform a group
of coordinated functions, tasks, or activities for the users.
Application Software
is designed to be a platform for other programs. Can be
classified as either operating systems (OS) or utility
