Question $5.(10$ points$)$ AMATConsider a system with L$-1$ and L$-2$ caches, main memory and disk $($or secondary memory$)$ withthe following parameters. It takes $10$ ns to access L$-1$cache, $100$ns to access L$-2$ Cache, $500$ nsto access RAM and $10$ms to access disk. A program makes $250,000$ memory references of which$215,000$ are hits in L$-1$ cache, $23,500$ are hit in L$-2$ cache, $2,450$ are hit in RAM.a$).$ What is the miss rate of L$-1,$ L$-2$ and main memoryb$).$ Estimate the AMAT assume all memory accesses are rea
