Given that main memory is composed of only three page frames for public use and that a seven-page program (with Pages a, b,c, d,e, f,g) that requests pages in the following order a, c,a, b,a, d,a, c,b, d,e, f

a.) Using the FIFO page removal algorithm, indicate the movement of the pages into and out of the available page frames (called a page trace analysis), Indicate each page fault with a asterisk(*). Then compute the faliure and sucess raitos.
b) Increase the size memory so it contains four page frames for public use. Using the same page requests as above and FIFO, do another page trace and analysis and compute the failure and sucess ratios.
c) What general statment can you make from this example? Explain your answer.

Miller company’s total sales are $171,000. the company’s direct labor cost is $20,520, which represents 30% of its total conversion cost and 40% of its total prime cost. its total selling and administrative expense is $25,650 and its only variable selling and administrative expense is a sales commission of 5% of sales. the company maintains no beginning or ending inventories and its manufacturing overhead costs are entirely fixed costs. required: 1. what is the total manufacturing overhead cost? 2. what is the total direct materials cost? 3. what is the total manufacturing cost? 4. what is the total variable selling and administrative cost? 5. what is the total variable cost? 6. what is the total fixed cost? 7. what is the total contribution margin?
