Information System (IS) Information System (IS) is a set of interrelated elements
that:
- collects (input)
-manipulates (process)
- stores- disseminates (output) data and information
- provides a corrective reaction (feedback mechanism) tomeet an objective
Ex. ATMs, airline reservation systems, course reservationsystems

Components of IS
-
8/12/2019 Is 101_Chapter 1
17/60
Elements of IS
1. People- qualified personnel to develop and maintain the system
- trainable users of the system or the operators
2. Computer equipment/hardwareused by the people to input,process, output activities
Input devices: keyboard, mouse, automatic scanning devices
Processing devices: computer chips that contains the CPU
and main memoryOutput devices: printer and computer screens or monitor
3. Softwareset of instructions that instructs the equipment what to
do

Elements of IS
3. Data or informationencoded and manipulated
4. Procedures/ guidelines includes methods and rules
used for the effective and optimal operation of thesystem
5. Telecommunication the media composed of the
hardware and software that facilitate the transmission of
electronic data within the system

DSS are a form of weak AI in the sense thatthey are not designed to operate autonomously,
but merely provide assistance to medical staff in
tasks that involve the manipulation of data andknowledge.
Such assistance may be to an inexperienced
doctor regarding diagnosis, or helping even anexperienced physician in a situation too complex
for them to handle alone.
