ELEMENTARY CONCEPT
1.1 Elementary Concept of System
System definition seen from procedure approach. System is a network work from procedure which interact, gathering together to do a activity or to finish a certain target.
Procedure is a correct medley from instruction step explaining what which must be done, who doing, when done and how doing
System definition seen from procedure component approach / element. System is corps from element which have interaction to reach specific-purpose.
1.1.1 System Characteristic
Component
· Component which interact, work along to form one union
· Supra System
Boundary
· Limiting system with the other system / external environment
Environments
· Any beyond the bounds of from system influencing system operation
Interface
· Interface Media of between one system sub with the other system sub
Input
· Energi included into system can be in the form of the input of treatment and input sinyal.
Output
· Result from energi processed and in klasifikasi become the output which is good for and rest of dismissal
Process
· Input Fox become the output
Objective/goal
· Otherwise own the goal hence operate for the system of there will be no utilizing. System told to succeed if when have hit the Objective/goal
1.1.2 Klafisikasi System
- Abstraction System [is] system in the form of opinion or idea. Follow the example of the : religion system, custom system.
Physical System [is] existing system in physical. Example : computer system, system akutansi, system produce.
- Natural System is system that happened through natural process. Example : gravitation system. Brand System [is] system entangling interaction [of] human being mechanically.Example : computer system, SI
- Certain System is system operating with the behaviour earn the diprediksi. Example : computer system.
System is not certain is system which its future condition cannot diprediksi. Example : system of product sale.
- Closed System is system which not correlate and is not imbued with external environment. Open System is coresponding system and there is influence environmentally outside.
1.2 Elementary Concept of Information
Information is data processed become the more form good for and more meaning for accepting
1.2.1 Information Cycle
Data processed by through a model become the information, receiver later;then accept the the information, making a[n data and conduct action, meaning to yield a other action to make a number of the data return.
The data will in catching as input, in process return to pass a model and so on form a cycle.
This cycle by John Burch referred as with the information cycle. This cycle in mentioning also with the data of processing cycles
1.2.2 Information Quality
Accurate
· Information free from the mistake and not deflect or mislead
Punctual
· Incoming information at receiver may not Lose time
Relevant
· Information have the benefit for the usage of its
1.2.3 Assess Information
Assess the information determined from two matter that is benefit and expense get. Information will be valuable if big added significance from expense get
