CEA201_Quiz 2

Which of the following is not a primary type of computer memory in a typical computer system?

• RAM

• ROM

• Cache

• HDD

What is a typical hierarchy for cache memory in modern computer systems, from fastest to slowest?

• L1 Cache, L2 Cache, Main Memory

• Main Memory, L1 Cache, L2 Cache

• L2 Cache, L1 Cache, Main Memory

• L1 Cache, Main Memory, L2 Cache

What is the primary advantage of cache memory in improving system performance?

• It increases the size of main memory

• It provides permanent storage for data

• It reduces the access time to frequently used data

• It enhances data security

What is the primary trade-off in cache design between larger cache sizes and smaller cache sizes?

• Larger caches provide better performance but consume more power

• Larger caches are more expensive but provide faster access times

• Smaller caches offer faster access times but are more expensive

• Smaller caches require more storage but have longer lifespans

In a direct-mapped cache, how many cache lines can map to the same set?

• one

• two

• four

• eight

In a memory system using Hamming code, if a single-bit error is detected and corrected, how many parity bits were likely involved in the correction?

• one

• two

• three

• four

What is the trade-off in memory systems when using Hamming code for error correction?

• Decreased error detection and correction capabilities with increased memory capacity

• Increased error detection and correction capabilities with reduced memory capacity

• Improved memory performance with no trade-offs

• Reduced error detection capabilities with increased memory capacity

In a memory system that uses Hamming code for error correction, if you have 7 data bits and 3 parity bits, how many bits can be corrected for single-bit errors?

• one

• two

• three

• four

In semiconductor main memory, what is the primary difference between SRAM (Static RAM) and DRAM (Dynamic RAM)?

• SRAM is faster but more expensive than DRAM.
  

• SRAM is volatile, while DRAM is non-volatile.

• SRAM uses capacitors to store data, while DRAM uses flip-flops.

• SRAM is used for main memory, and DRAM is used for cache memory.

What is the primary purpose of RAID configurations in computer systems?

• To increase data storage capacity

• To improve data access speed

• To enhance data security and fault tolerance

• To reduce power consumption
