Notes for RGPV

I am doing B.Tech from Rajiv Gandhi Proudyogiki Vishwavidyalaya (RGPV). I need important notes of Cloud Computing topic. So will you give link from where I will download notes of Cloud Computing topic of B.Tech Course of RGPV?

As you are looking for important notes on Cloud Computing topic, so here I am providing following notes for you:

RGPV Cloud Computing Notes 1
UNIT- I
A system is a set of interacting or interdependent components forming an integrated whole or a set of elements (often called’ components' ) and relationships which are different from relationships of the set or its elements to other elements or sets.
Fields that study the general properties of systems include Systems science, systems theory, cybernetics, systems, thermodynamics, and complex systems. They investigate the abstract properties of systems' matter and organization, looking for concepts and principles that are independent of domain, substance, type, or temporal scale.
Some systems share common characteristics, including:
• A system has structure, it contains parts (or components) that are directly or indirectly related to each other;
• A system has behavior, it contains processes that transform inputs into outputs (material, energy or data);
• A system has interconnectivity: the parts and processes are connected by structural and/or behavioral relationships.
• A system's structure and behavior may be decomposed via subsystems and sub-processes to elementary parts and process steps.

Types of System:-
Systems are classified in different ways:
1. Physical or abstract systems.
2. Open or closed systems.
3. 'Man-made' information systems.
4. Formal information systems.
5. Informal information systems.
6. Computer-based information systems.
7. Real-time system.

Systems are of the following two types basically:-
Physically System: - the word system has a technical meaning namely; it is the portion of the physical universe chosen for analysis. Everything outside the system is known as the environment, which in analysis is ignored except for its effects on the system. The cut between system and the world is a free choice, generally made to simplify the analysis as much as possible. An isolated system is one which is supposed to have negligible interaction with its environment.
Often a system in this sense is chosen to correspond to the more usual meaning of system, such as a particular machine. But physical systems are often more esoteric: an atom, the water in a lake, or indeed the water in the left-hand half of a lake can all be considered as physical systems. In the study of quantum decoherence the "system" may refer to the macroscopic properties of an object (e.g. the position of a pendulum bob), while the relevant "environment" may be the internal degrees of freedom, described classically by the pendulum's thermal vibrations

Conceptual System: - A conceptual system is simply a conceptual model. There are no limitations on this kind of model whatsoever accept those of human imagination. If there is an experimentally verified correspondence between a conceptual system and a physical system then that conceptual system models the physical system. "Values, ideas, and beliefs that make up every persons view of the world": that is a model of the world; a conceptual system that is a model of a physical system (the world). The person who has that model is a physical system.

In psychology and social work, when they talk about a conceptual system, they are referring to some person's model of the world, but if they try to understand that model, they end up making a model of that model, which is just a model of the person's behavior. In any case, this is exactly the purpose of the general term "conceptual systems".

Differentiate between natural and man-made systems.
There are natural and man-made (designed) systems. Natural systems may not have an apparent objective but their outputs can be interpreted as purposes. Man-made systems are made with purposes that are achieved by the delivery of outputs. Their parts must be related; they must be “designed to work as a coherent entity” - else they would be two or more distinct systems

Elements of a System:-
Following are considered as the elements of a system in terms of Information systems: –
1. Inputs and outputs
2. Processor
3. Control
4. Environment
5. Feedback
6. Boundaries and interface
