1.Hardware
Hardware
is the most obvious part of a computer-based information system. Hardware
refers to the computers themselves, along with any and all peripherals,
including servers, routers, monitors, printers and storage devices. A CBIS may
use a single computer or thousands.
2.Software
Without
software, the hardware wouldn't be very useful. Software, the second element of
a CBIS, is what tells the hardware how to function. It gathers, organizes and
manipulates data and carries out instructions. Everything you do using a
computer is done by the software.
3.Data
Data,
or information, is the third element of a CBIS. Just as hardware cannot
function without software, software cannot function without data. This is the
information part of an information system, and whether that is statistical
data, sets of instructions, lists of names or even graphics and animations, it
is all key to a CBIS.
4.Procedures
It is
commonly said that "procedures are to people what software is to
hardware." The fourth element of CBIS, procedures are the rules,
descriptions and instructions for how things are done. In computer-based
information systems, procedures are frequently covered in instruction or user
manuals that describe how to use the hardware, software and data.
5.People
People
are the most often overlooked and most important part of a computer-based
information system. It is people who design and operate the software, input the
data, build the hardware and keep it running, write the procedures and it is
ultimately people who determine the success or failure of a CBIS.
6.Communication
Communication is left out of some
lists of CBIS elements, but for a CBIS that involves more than one piece of
hardware to function, communication or connectivity is a necessity. This is, in
part, because parts of it are covered under hardware. The components that allow
one computer to communicate with another are hardware and are controlled by
software. If communication between people is included in this element, though,
it is an important element.
