Write a program that simulates a paging system using the aging algorithm. The number of page frames is a parameter. The sequence of page references should be read from a file. For a given input file, plot the number of page faults per $1000$ memory references as a function of the number of page frames available.

Write a program that simulates a toy paging system that uses the $\text{WSClock}$ algorithm. The system is a toy in that we will assume there are no write references (not very realistic), and process termination and creation are ignored (eternal life). The ... per $1000$ memory references. Explain what is needed to extend the program to handle a page reference stream that also includes writes.

We consider a program which has the two segments shown below consisting of instructions in segment $0,$ and read/write data in segment $1.$ Segment $0$ has read/execute protection, and segment $1$ has just read/write protection. The memory system is a demand- paged virtual memory system ... $16$ Fetch from segment $1,$ page $4,$ offset $28$ Jump to location in segment $1,$ page $3,$ offset $32$

It has been observed that the number of instructions executed between page faults is directly proportional to the number of page frames allocated to a program. If the available memory is doubled, the mean interval between page faults is also doubled. Suppose that a normal instruction ... which time it gets $15,000$ page faults, how long would it take to run if twice as much memory were available?
