Discussion
C : Computer System
T : Dumb Terminal
The given diagram most appropriately represents which of the following scenario ?
Answer: A
The diagram represents a Centralized system.
All the processing is done by one computer system, C, and the dumb terminals, T, have no processing power of their own. They only send keystrokes to the central computer and display what it returns. A single computer serving many terminals is the classic centralized (time-sharing mainframe) arrangement.
A distributed system would need several computers, each with its own processing, cooperating over a network. Local-access and remote-access describe how a user reaches a computer, not the architecture shown, in which everything depends on the one central system.
