Question: Discuss About The Software Engineering Science Programming? Answer: Introduction Most of the computer-based systems are distributed systems, the processing of information over several computerized machines in place of a single machine (Khan and Sayed 2017). Thus, distributed models in software engineering have become a vital part of the enterprise computer system which includes Databases, file systems, operating system and the internet. Here, we are choosing two main distributed architecture Client-server architectures and Master/slave architecture. Compare and Contrasting Distributed Models In the Client Server Architecture/Model the application process has been divided into different services in the network where each of the network process is either a server or a client. These services are provided by the servers and the clients. The two main implementation of this architecture are Thin-client here the servers completes the processes and then manages the data, this model allows to store the data centrally, the information and applications are efficiently distributed to the clients and Fat-Client model servers are only responsible for managing and maintaining the data. The applications and interaction with the system that manages the system software are executed by the software residing on the client machine (Robi, Mostafa and Khan 2016). In the Master Slave Architecture/Model, the master sends the task and the slave picks up the job and then processes them. The pattern balances the system sinec the workers distributes the load. Advantages of Client server Model: Thin clients are able to have inexpensive computing boxes. Provides way to build hybrid architecture The client server environment allows the organization to maximize the benefit of the micro technology. At the fraction of the cost of mainframes the PCs can deliver extraordinary power. Facilitates efficient processing and thus processing are done close t the data sources. Facilitates use of interfaces. Disadvantage of Client server Model: Congestion in Network Not as robust as a P2P It is very expensive to install and manage Needs professional IT people to maintain the servers Advantage of Master Slave Model: There are multiprocessor in the system, and all the processors are on the same level, there has no master-slave class All processors can process and interrupt and tasks Disadvantage of Master Slave Model: The master processor gets overloaded The operating system run by the master processor, could fall behind the processors running users applications Rationale The distributed object-oriented framework designs client/server advancements. Despite the fact that customer/server frameworks are by and large described by their segments, they should serve basic capacities keeping in mind the end goal to meet the requests of arrange figuring. customer/server frameworks have developed more powerful, the figuring group has recognized their numerous unmistakable preferences. Conveyed objects guarantee to alter the development of scalable customer/server frameworks by giving modularized programming that highlights tradable parts. Circulated objects mix the dissemination preferences of client/server innovation with certifiable data contained in object-oriented models. References Khan, M.Y.A. and Sayed, M.A., 2017.
