3: given that main memory is composed of three page frames for public use and that a program requests pages in the following order: a, b, a, b, f, d, f, c, g, f, g, b, d, e a) using the fifo page removal algorithm, perform a page trace analysis indicating page faults with asterisks (*). then compute the failure and success ratios. b) using the lru page removal algorithm, perform a page trace analysis and compute the failure and success ratios c) what conclusions do you draw from this comparison of fifo and lru performance? would you make general statements from this example? explain why or why not.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
