How do you account for higher scalability and reliability of computer network?
Ans: Computer network will have a large number of computers, which can share database, software and other resources. In the event of failure of one computer, its workload will be taken over by other computers. So, it gives higher reliability than centralized computing system.
Requirement of software, database, hardware etc. increases gradually. In centralized computing system, if one computer is not able to serve the purpose, we have to replace it by new one. Replacement of new computer needs lot of investment and effort, which will be avoided in computer network system. If there is require for more, one can buy another powerful computer, add it to computer network and utilize it. The several resources like computers, peripherals, etc. will be added in a scalable manner.
