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, C, D, A, B, E, A, B, C, D, E, B, A, B
- Using the FIFO page removal algorithm, perform a page trace analysis indicating page faults with asterisks (*). Then compute the failure and success ratios
- Using the LRU page removal algorithm, perform a page trace analysis and compute the failure and success ratios.
The page trace analysis should look something like the image below. It should clearly specify which page is loaded into each of the page frames as the requests come in.

Given that main memory is composed of four page frames for public use and that program requests pages in the following order: a, b, a, b, f, d, f ,c, g, f, a, b, d, e, k, m Using FIFO removal algorithm, perform a page trace analysis and indicate page faults with asterix(*). Then calculate failure rate. Using LRU removal algorithm, perform a page trace analysis and indicate page faults with asterix(*). Then calculate failure rate.

1. 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) indicating each page fault with an...

forehand e receiver creates a public key and a secret key as follows. Generate two distinct primes, p andq. Since they can be used to generate the secret key, they must be kept hidden. Let n-pg, phi(n) ((p-1)*(q-1) Select an integer e such that gcd(e, (p-100g-1))-1. The public key is the pair (e,n). This should be distributed widely. Compute d such that d-l(mod (p-1)(q-1). This can be done using the pulverizer. The secret key is the pair (d.n)....
