Solution
The correct answer is d. Both Data-server systems and Transaction-server systems allow clients to interact with the servers by making requests to read or update data, in units such as files or pages.
Here's why:
a. Transaction-server systems do allow clients to interact with the servers by making requests to read or update data, but the units are not necessarily files or pages. They could be transactions or operations.
b. Data-server systems do provide an interface to which clients can send requests to perform an action, but they don't necessarily execute the action and send back results to the client. They may just provide the data requested.
c. This is partially correct. Data-server systems do allow clients to interact with the servers by making requests to read or update data, but again, the units are not necessarily files or pages.
e. This is incorrect because both Data-server systems and Transaction-server systems do provide an interface to which clients can send requests to perform an action.
