22. System Area Network is used to provide high-speed connection in which of the following environments?
[A] Server-to-server application
[B] Storage Area Network
[C] Processor-to-Processor application
[D] All of the Above
Show Answer
Correct Answer: D [All of the Above]
Notes:
System Area Network is used to explain a relatively local network that is designed to provide high-speed connection in server-to-server applications, storage area network and processor-to-processor applications. The computers connected on a SAN operate as a single system at very high speeds.
23. Which of the following networking devices forwards data packets between computer networks?
[A] Router
[B] Gateway
[C] Switch
[D] Hub
