ELEMENTARY CONCEPT :
- What that System ?
- What is Information?
- What is Information System?
- Who got mixed up with Information System?
- Why need Information System?
- How to develop Information System?
What is System ?
System definition can be seen from two approach, that is approach of procedure and approach of component / element
System is a network work from procedures which is interaction, gathering together to do an activity or to finish a certain target
Procedure is a correct medley of instruction steps explaining what which must be done, who doing, when done and how do it
- System is corps of elements which is have interaction to reach specific-purpose.
- SYSTEM : a. reaching a target ( Goal)
b. reaching a target (Objective)
CHARACTERISTIC SYSTEM
- Components
- Component which interact, work along to form one unity.
- Supra System
- Boundry
- Limiting system with other system / external environment
- Environment
- Any beyond the bounds of from system which is influence system operation
- Interface
- Link media between one system sub with other system sub
- Input
- included Energi into system can in the form of treatment input and input of sinyal
- Output
- Result of from processed energi and classified to become output which good for and rest of dismissal
- Process
- Change input become output
- Target ( objective) / Target (goal)
- Otherwise have the target of hence system operation there will be no utilizing of. System told to succeced when have hit target / its target
The Classification Of System
a. Deterministic System
The Certain system operate with behaviour which have earned can be predicted, interaction between its sharess can be detected categorically so that its output can be forecasted. for example of : Computer programe, executing precisely as according to its instruction network. System of pay, and others.
b. Probabilistic System
The System which is input and its process can be defined, but yielded output cannot be determined categorically; ( always there is a little mistake / deviation to forecast of the way system). for Example : marketing system)
c. Open System
The system that relation and effect external environment .This system accept input and yield output for external environment / the other sub system, so that have good operation system. This system tend to measure up to adaptation, can adapt to its environment so that can continue its.
d. Closed System
The System Physical where the process that happened do not experience of transfer of items, information or energy with environment outside system. This system work automatically without existence of interfere in of external side of it.
e. Relatively Closed System
The closed System but doesn’t closed at all to accept other influences. This system in its operation can accept influence from outside which have been defined in certain boundarys.
f. Artificial System
The System imitating occurence in system. This system is formed pursuant to occurence in nature where human being unable to do it. Equally imitat exist in nature.
g. Natural System
The natural System is occurence in nature. for Example of : sea, solar system and others.
h. Manned System
The System explanations of behaviour covering human being taking part in. This system can be depicted in way of as follows:
The System of Human being focus the relations between human being
The System of Human being – Machine, System which involve machine to a target
The Machine System, automatic system where human being have duty to start and finish system, meanwhile human being entangled also to monitor system.
Information
Data is fact. Information is data that processed become better form and more meaning to accept it. If data is not useful to accept it so the data cannot be referred as by information.
Quality Of Information
To get information with quality, then information must have:
Accurately : Information free from mistakes and doesn’t deflect or mislead
Punctually : Incoming information at receiver may not lose time
Relevantly : Information is have benefit for its usage.
Information will be valuable if big added significance of expense get it
