g Assume a two level cache with a 99% hit rate in L1 and an 85% hit rate in L2. Hits in L1 take 2cycles, while those in L2 take 10 cycles (i. e., L2 hit takes 10 cycles), and a miss in both cachesthat goes to memory takes 100 cycles. What is the average access time for this memory system, in cycles?

Consider how gaming consoles initially relied on joysticks and joypads and then made the switch to modern gaming controls, which include analog sticks, buttons and switches, touch controls, accelerometers, motion controls, etc. name at least two kinds of gaming experiences that are possible with these new control devices but were not possible on original joysticks. explain how new technologies made this newer game style possible.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
