Write a function sequence that takes 3 arguments low, high, and fac, all assumed to be positive integers. Further assume factor is greater than 1. sequence produces a geometric sequence from low to high (including low and possibly high) where the sequence has a factor of fac between each two numbers. If low is greater than high, the sequence should be an empty list.

When jen is planning to upgrade to a monitor with a better resolution, what should she be looking for in the new monitor?

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
