Distributed Computing Environment: Solution for Company's Computing Needs, Exercises of Object Oriented Programming

Baddi University of Emerging Sciences and TechnologiesObject Oriented Programming

The benefits and suitability of a distributed computing environment for a company's computing needs. That distributed processing refers to using multiple computers or processors to run an application, and highlights the economical, high computing power, data processing capability, reliability, and incremental growth advantages of such systems. The document also mentions that sophisticated software is used to detect idle cpus and distribute programs.

Solution No. 2

Distributed computing environment will be the suitable solution for this company. Distributed processing refers to any of a variety of computer systems that use more than one computer, or processor, to run an application. More often, however, distributed processing refers to localโ€area networks (LANs) designed so that a single program can run simultaneously at various sites. Most distributed processing systems contain sophisticated software that detects idle CPUs on the network and parcels out programs to utilize them. ๏ƒ˜ Economical Share the cost of expensive resources. ๏ƒ˜ High computing power High computing power (since more than one machines are involved) ๏ƒ˜ Data Processing Capability is flexible Can be increased by distributing the task on multiple machines) ๏ƒ˜ Reliability If one machine crashes, the system as a whole can still survive ๏ƒ˜ Incremental growth : Computing power can be added in small increments.
