(1) Suppose you have the new Zarnex VQ-120 computer which has a 64-bit architecture. Further, the boss has

told you to max out the memory, which, on that machine, means you can install all the memory the architecture

supports: how many bytes is that? At contemporary memory pricing of D $7 / GB, how much will it

cost to fill the machine? Knowing what you know about virtual memory, how much will it cost to provide

disk space only for paging assume you need 2 ~ real memory size for paging space, as many systems recommend.

Use a price of $35/TB for disk pricing. Remember to include correct units on all your results

the result isnt completely correct without them.

2) You are to compare reading a file using a single-threaded file server and a multi-threaded server. It takes 15

ms to handle a request assuming the needed data are in memory. If a disk operation is needed, as happens

1/3 of the time, an additional 75 ms is required, during which time the thread is blocked. How many requests

per second can the server handle if it is single-threaded? if it is multi-threaded using user-level threads? kernel

level threads?

These are only questions that was gevin.
