**Question:**A CPU is equipped with a cache. If it takes 4 ns to access the data from the cache and 200 ns to access data from the main memory, what is the effective memory access time if the hit ratio is 95%?**Answer =** _______________ ns---To solve this, you can use the formula for effective memory access time (EMAT):\[ \text{EMAT} = (\text{Hit Ratio} \times \text{Cache Access Time}) + (\text{Miss Ratio} \times \text{Main Memory Access Time}) \]Given:- Cache Access Time = 4 ns- Main Memory Access Time = 200 ns- Hit Ratio = 95% = 0.95- Miss Ratio = 1 - Hit Ratio = 0.05Substitute the values into the formula to find the effective memory access time.
