Where n≥1 and the pi and qi are propositional variables. This formula has length 4n−1, if we count each occurrence of a propositional variable or an operator as adding 1 to the length and ignore the implicit parentheses. (a) Write out a conjunctive normal form of this formula in the case n=3. (b) How long is your conjunctive normal form of this formula, using the same conventions as above? For

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?
