doubt
A computer has a cache, main memory, and a disk used for virtual memory. An access to the cache takes 10 ns. An access to main memory takes 100 ns. An access to the disk takes 10,000 ns. Suppose the cache hit ratio is 0.9 and the main memory hit ratio is 0.8. The effective access time (EAT) required to access a referenced word on this system is ______________ ns.
