Ok. Let us go ahead

 

thank u ram Give me the definition of a system and types of systems

System is defined as i. an orderly arrangement of a set of interrelated 2. and interdependent elements 3. that operate collectively 4. to accomplish some common purpose or goal.

Based on elements : Abstract , Physical Based on Interactive behaviour : Open , Closed Degree of Human Intervention : Manual, Automated Based on output :Deterministic, Probabilistic

Abstract system is orderly arrangement of IDeas, it is conceptual system which is written in papers or ideas not physically implemented one. Physical system is a tangible one which operates to accomplish a task or a goal

Open system : which interacts freely with environment by taking input and giving output eg: Educational systems, All business enterprises if they are open system they cannot survive Closed System: Which does not interact with environment

abstract system is an orderely arrangement of Inter-dependent ideas, principles or concepts. pls. underline the word Inter-dependent... most important point

 

closed system do not get any feed back whereas open system gets feedbak from their external environment for their survival

In terms of conitinuity, closed system will vanish fast as they dont have any interaction from the environment wheras the open system , sustain for a period of time by generating suplus out of its process.

Entropy is the quantitative measure of disorder in a system. Systems can run down on account of disorder or disorganized. The offsetting an increase in entropy requires inputs of matter and energy to repair, replenish and maintain the system. This maintenance input is termed as Negative Entropy. Open systems require more negative entropy as they interact with the environment frequently. In general, the life cycle of a closed system is much shorter compared to that of an open system because it decays faster for not having any input/ interaction from environment.

khushboo u tell subsystem its chraracteristics

A subsystem is a part of larger system. Each system is composed of subsystems which is once again made up of subsystems. The interconnections and interactions between the subsystem are called interfaces

Interface occurs at the boundary and takes the form of input and outpout

Decomposition is one of the character of subsystem : Because it is difficult to change or update the entire system as a whole so it will decomposed and handled
