A System Development Life Cycle is the process of developing a system or software. Prototype is the process of creating examples of software applications,
In throwaway prototype model we discard the prototype and start from scratch. In evolutionary prototype model we make changes in the prototype and refine it.

prototyping is an approach to e development to a system where software simulates the aspects of an actual processing system, in simple words prototyping can be called as a shorter version of working system, thanks Bharat Kumar Mishra bharat9234@yahoo.com
Rapid Prototyping Model Rapid prototyping has long been used in the development of one-off programs, based on the familiar model of the chemical engineer's pilot plant. More recently it has been used to prototype larger systems in two variants-the "throwaway" model and the "operational" model, which is really the incremental model to be discussed later. This development process produces a program that performs some essential or perhaps typical set of functions for the final product. A throwaway prototype approach is often used if the goal is to test the implementation method, language, or end-user acceptability. If this technology is completely viable, the prototype may become the basis of the final product development, but normally it is merely a vehicle to arrive at a completely secure functional specification, as shown in Figure 1.4. From that point on the process is very similar to the waterfall model. The major difference between this and the waterfall model is not just the creation of the operational prototype or functional subset; the essence is that it be done very quickly-hence the term rapid prototyping.3 Prototype model In this model, a prototype (an early approximation of a final system or product) is built, tested, and then reworked as necessary until an acceptable prototype is finally achieved from which the complete system or product can now be developed. Prototype paradigm begins with requirements gathering. Developer and customer meet and define the overall objectives for the software, identify whatever requirements are known, and outline areas where further definition is mandatory. A quick design occurs which leads to the construction of prototype. The prototype is evaluated by the customer/user and used to refine the requirements for the software to be developed. Iteration occurs as the prototype is tuned to satisfy the user requirements, while at the same time enabling developer to better understand what needs to be done.
Open-source is a development model. Windows is an operating system.
In throwaway prototype model we discard the prototype and start from scratch. In evolutionary prototype model we make changes in the prototype and refine it.

Management development is appropriately called Manager Development and focuses on individual manager. Organisational development includes management development efforts but focuses on improving the system that make up the total organisation.
SDK is a Software Development Kit used to create applications. OS is an Operating System and is the platform which applications run on.
