Chapter 10, Problem 1PE
Explanation of Solution
Choice between the two:
The choice for storing files each of size 2 kilobytes would be key value store.
Reason:
- The distributed file
system is designed to store moderate numbers of large file. - Each file block containing with multiple megabytes and each kilobyte sized files will result in lot of wasted space in each block and will have a poor storage performance.

Challenge: Assume that the assigned network addresses are correct. Can you deduce (guess) what the network subnet masks are? Explain while providing subnet mask bits for each subnet mask.
[Hint: Look at the addresses in binary and consider the host ids]
I would like to know if my answer statment is correct?
My answer:
The main difference is how routes are created and maintained across different networks. Static routing establishes router connections to different networks from the far left and far right. The Dynamic routing focus emphasizes immediate connection within the router while ignoring the other connections from different networks. Furthermore, the static routing uses the subnet mask to define networks such as 25.0.0.0/8, 129.60.0.0/16, and 200.100.10.0/30, which correspond to 255.0.0.0, 255.255.0.0, and 255.255.255.252. On the other hand, dynamic routing uses the wildcard mask to inverse the subnet mask, where network bits become 0 and host bits become 1, giving us 0.0.0.255, 0.0.255.255, and 0.0.0.3. Most importantly, the CLI commands used for Static and Dynamic routing are also different. For static routing, the “IP route” corresponds with the network, subnet mask, and next-hop IP address. In contrast, dynamic routing uses…

- Consider N processes sharing the CPU in a round-robin fashion (N>=2). Assume that each context switch takes S ms and that each time quantum is Q ms. For simplicity, assume that processes never block on any event and simply switch between the CPU and the ready queue. Also, assume that a process is still in the ready queue while a context switch is happening. a) What happens if Q is much smaller than S? What happens when Q→→ ∞, i.e. is much larger than the maximum turnaround time of all the processes?
