Suppose a computer system has a memory organization with only three levels of hierarchy, a cache, a main memory and a hard drive. Access times and miss rates are given in Table below. Now find the followings: Access Time Memory Unit Hit Rate (Cycles) Cache 90% Main memory 105 95.50% Hard drive 1,080,000 0% 1. Miss rate of the main memory. 2. Average memory access time. 3. For 1350 cache hits, find the number of total cache accesses while hit rate is given in Table 4. If number of hits are 1350 and cache hit rate is given in Table then how many times data has been provided from main memory?

Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
