24. With good speed-up, if transction volumes grow, response time can be kept constant by adding hardware resources such as CPUs.
- TRUE
- FALSE
25. Parallel database systems can make it possible to overcome the limitations, enabling a single system no serve thousands of users.
- TRUE

26. In a parallel database system, muliple CPUs are working in parallel and are physically located in a close environment in the same building and communicating at a very high speed.
- TRUE

27. Parallel processing divides a large task into many smaller tasks and executes the smaller tasks concurrently on several nodes (CPUs)
- TRUE
- FALSE
28. The goal of parallel database systems is usually to ensure that the database system can continue to perform at an acceptable speed, even as the size of the database and the number of transactions increases

29. In a shared-disk system, multiple CPUs are attached to an interconnection network through a node and each CPU has a local memory and disk storage, but no two CPUs can access the same disk storage area.
- TRUE
- FALSE
30. In a shared-nothing system, multiple CPUs are attached to an interconnection network and each CPU has their own memory but all of them have access to the same disk storage or, more commonly, to a shared array of disks.
