An alternative strategy for the expo function uses the following recursive definition: expo (number, exponent) =1, when exponent = 0 = number * expo(number, exponent - 1), when exponent is odd = (expo (number, exponent//2))2 , when exponent is even Does this strategy reduce the computational complexity? Explain. You may use Big-O notation concept.

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e.g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?

This chapter lists many ways in which becoming computer literate is beneficial. think about what your life will be like once you’re started in your career. what areas of computing will be most important for you to understand? how would an understanding of computer hardware and software you in working from home, working with groups in other countries and contributing your talents.
