PARTS OF AN INFORMATION SYSTEM
An information system is a collection of people, procedures,
software, hardware and data which works together to provide
information essential to running an organization.
People. People are competent end users working to increase their
productivity.
End users use hardware and software to solve information-related or
decision-making problems.
Procedures. Procedures are manuals and guidelines that instruct end
users on how to use the software and hardware.
Software. Software is another name for programs-instructions that tell
the computer how to process data. There are basically two kinds of
software:
System Software. System software is background
software that helps a computer manage its internal
resources. An example is the operating system. ( e.g
Windows and Linux )
Application Software. Application software performs
useful work on general-purpose problems. The two types of
applications software are basic applications and advanced
applications.
Basic applications include:
Browsers- navigate, explore, find information on the
Internet.
Word processor- prepare written documents.
Spreadsheet- analyze and summarize numerical
data.
Database management system- organize and
manage data and information.
, Presentation graphics- communicate a message or
persuade other people.
Advanced applications include:
Multimedia- integrate video, music, voice, and
graphics to create interactive presentations.
Web publishers- create interactive multi-media Web
pages.
Graphics programs- create professional publications,
draw, edit, and modify images.
Virtual reality- create realistic three-dimensional
virtual or simulated environments.
Artificial intelligence- simulated human thought
processes and actions.
Project managers- plan projects, schedule, people,
and control resources.
Hardware. Hardware consists of input devices, the system unit,
secondary storage, output devices, and communication devices.
Input Devices. Input devices translate data and programs that
humans can understand into a form the computer can process. The
more common are the keyboard, mouse, scanner, digital camera and
microphone.
The System Unit. The system unit consists of electronic circuitry with
two parts:
Central processing unit (CPU)- controls and manipulates data to
produce information.
Memory (primary storage)- temporarily holds data, program
instructions, and processed data.
Secondary Storage. Secondary storage stores data and programs.
Three most common storage media are: flash drive, hard disk and
optical disk.
