What is a key feature of symmetric multiprocessors (SMPs)?

• Each processor has its own independent memory

• Memory access time is uniform across all processors

• Only one processor is active at a time

• Processors execute instructions in a strict sequence

Which protocol is commonly used to manage cache coherence in multiprocessor systems?

• FIFO

• MESI

• SMP

• MIMD

According to Flynn's taxonomy, which system type involves a single instruction controlling multiple data streams?

• SISD

• SIMD

• MISD

• MIMD

What is one primary goal of multithreading in processor systems?

• Reduce memory capacity

• Enhance instruction-level parallelism

• Limit access to shared resources

• Ensure strict sequential execution

What distinguishes a nonuniform memory access (NUMA) system from an SMP?

• NUMA systems have uniform memory access times across processors

• NUMA systems use a single instruction stream for all processors

• NUMA systems allow memory access times to vary across processors

• NUMA systems do not use a shared memory model

In a cluster configuration, communication between computers is primarily achieved through:

• Shared memory

• A network facility or fixed paths

• MESI protocol

• SIMD instructions

Which type of system in Flynn's taxonomy is currently not commercially implemented?

• SISD

• SIMD

• MISD

• MIMD

What is the purpose of instruction pipelining in processor systems?

• To execute instructions sequentially

• To allow parallel fetching and executing of instructions

• To reduce processor clock speed

• To synchronize memory access times

Which system uses a single control unit that feeds a single instruction stream to multiple processing units?

• SISD

• MIMD

• SIMD

• NUMA

Cloud computing architecture primarily supports:

• Multithreaded processing only

• Localized computing with dedicated hardware

• Distributed computing and resource sharing over the internet

• Only SMP configurations
