State True/False

1.With a good scale-up, additional CPUs reduce system response time.
2.Synchronisation is necessary for correctness.
3.The key to successful parallel processing is to divide up tasks so that very little synchronisation is necessary.
4.The more is the synchronisation, better is the speed-up and scale-up.
5.With good speed-up, if transaction volumes grow, response time can be kept constant by adding hardware resources such as CPUs.
6.Parallel database systems can make it possible to overcome the limitations, enabling a single system to serve thousands of users.
7.In a parallel database system, multiple CPUs are working in parallel and are physically located in a close environment in the same building and communicating at a very ...
