Distributed System


Distributed System or Distributed Computing System are those systems which are very cost effective.In distributed system all links are distributed at multiple sites.In this system,all the nodes are interconnected to each other.Example:-cyber cafe type environment.

Advantage of Distributed System:-

1)Very cost effective.

2)Response time is very less.

3)It is reliable.

4)It is flexible.

5)Most of the time result will good.

Disadvantage/Limitations of Distributed System:-

1)Security concern.

2)Maintenance problem.

That's all about Introduction/coarse of distributed system with its definition,If you have any query then leave your comments and don't forgot to follow me on Google+,Facebook,Twitter.

Real Time System


Real Time System are those systems which are analyse,monitor the real world event.As a name suggest real time system works in real time environment.

Real time systems can complete their work at a specified time period but it was not sure whether our work should be o.k. or not.Let us take an examples:-

->Example of Missile Launching:-This program should done in specified time period but we don't know whether our result is positive or negative.

->Example of bomb testing:-Like as above example.

->Train Timing(Embedded from its source to destination):-If we fail in some process,may be loss/crash of trains.

Automated System


The definition/meaning of Automated System is quite simple means Automated System are those system which include computerised component for data collection/processing etc.

In Physical system each process is done by human being  but in automated system all process is done by computer.


Advantage of Automated System:-



1)Automated system is very fast as compared to Manual system.

2)No meaning of tiredness.


3)Storing capacity is high.


4)Speed is fast.


5)Less chance of happening of mistakes etc.

Manual System


The definition/meaning of Manual System is quite simple means Manual System are those system which include manual efforts for data collection/processing etc.

In automated system each process is done by processor of computer but in manual system human being is a processor who can do efforts to perform a task.


This concept is used in SSAD(Structured System Analysis and Design).


Dis-Advantage of Manual System:-


1)Manual system is very slow as compared to automated system.


2)Its lazy.


3)Get tired very quickly.


4)Storing capacity is limited.


5)Speed is slow.


6)More chance of happening of mistakes etc.

Abstract System


The definition/meaning of Abstract System is quite simple means abstract system are those system which are design before physical system.

All non working system are called as Abstract System.Abstract system is non-tangible means we can't touch,see the system.Example Algorithm.

This concept is used in SSAD(Structured System Analysis and Design).

Physical System


The definition/meaning of physical system is quite simple means physical system are those system which are created after abstract system.

All working system are called as Physical System.Physical system is tangible means we can touch,see the system.Example of Physical System is Television.

This concept/theory is used in SSAD(Structured System Analysis and Design).

Closed System


Closed System are those system which are not freely interact with environment,means those system which are not adaptable for change.Closed system has shorter life span as compared to open system.The maintenance of closed system is simple.Closed system can except only known inputs and provide only known output.Example of close system is Nuclear Reaction. 

Type of closed system:-


1)Relatively closed:-Relatively closed but interact with environment.


2)Absolutely closed:-Absolutely closed but does not interact with environment.



Advantage/characteristics/features and disadvantages of Closed System:-


1)Life span is short.


2)Not easily changed.


3)Very rarely used in environment.


4)Maintenance is easy as compared to open system.

Open System


Open System are those system which are freely interact with environment,means those system which are adaptable for change.Opened system can change their process and input to provide required output.Open system has longer life span as compared to closed system.The maintenance of open system is difficult.Open system can except both known and unknown inputs and provide known and unknown output.Example of open system is our biological system,business system etc.

Advantage/characteristics/features of Open System:-


1)Take useful output and produce useful output.


2)Open system has the predefined goal.


3)It has longer life span.


4)Easily changeable.



That's all about open system and its examples(in ssad,computer science,system analysis)

What is System|Features of System|Type of System


System:-System is a collection of component which work together to perform a task.System contain input,process it and provide the appropriate output.System is a interdependent group of component which are linked together to perform a goal or their objective.Example of System are like marketing system,information system,business etc.

Characteristics/Features/advantage of System:-

1)All System has predefined objective.

2)All System component are interrelated to each other.

3)System are divided into sub system and sub system are also divided.

4)System can perform integration.

Elements of System:-3 main element of system are as follow:-

1)Input
2)Process
3)Output

Type of System:-

1)Physical System:-Physical System are those system which are visible to us.Example T.V.

2)Abstract System:-Abstract System are those system which are not visible to us(only conceptually present).Example Algorithm.

3)Open System:-Open System are those system which are freely interact with environment.

4)Closed System:-Close System are those system which are not freely interact with environment.

5)Deterministic and probabilistic System:-Deterministic system are those system which give appropriate output but Probabilistic system give expected output.

6)Manual and Automated System:-Manual System are those system which contains manual efforts for data collection whereas Automated System contains computerised effort.
