  1. Question 1

    Q1. What is the hit ratio of a cache memory if the cache access time is 10 ns and main memory access time is 100 ns, and the effective access time is 15 ns?

    • A) 0.85
    • B) 0.9
    • C) 0.95
    • D) 0.98

    Answer: 0.95

    Explanation: Using the formula: Effective Access Time = Hit Ratio * Cache Access Time + (1 - Hit Ratio) * Main Memory Access Time, we can solve for Hit Ratio.
