Answer 1

• For a multiprocessor system, interconnection network - crossbar switch is an example of a non- blocking network. A non-blocking network is a type of interconnection network in which concurrent communication can occur between multiple nodes without blocking. 

• The crossbar switch is a non-blocking network because it can connect any input to any output without any blocking. This allows for efficient communication and data transfer between multiple processors, memory modules, and input/output devices in a multiprocessor system. 

• Hence, the correct answer is option 1.
