1. How is a Network Layer protocol different from a Transport Layer protocol?

2. Into which Class of networks do the following IP Addresses fall?

a.) 180.265.14.3

b) 218.193.149.222

c) 92.146.292.7

3. Into which class of networks do the following IP addresses fall?

a.) 223.52.176.62

b.)127.255.255.2

c.) 191.57.229.163

4. Calculate the overall speedup of a system that spends 65% of its time on I/O with a disk upgrade that provides for 50% greater throughput.
5. Calculate the overall speedup of a system that spends 40% of its time in calculations with a processor upgrade that provides for 100% greater throughput.

6. Amdahl's Law is as applicable to software as it is to hardware. An oft-cited programming truism states that a program spends 90% of its time executing 10% of its code. Thus, tuning a small amount of program code can often time have an enormous effect on the overall performance of a software product. Determine the overall system speed up if:

a. 90% of a program is made to run 10 times as fast (900% faster)

b. 80% of a program is made to run 20% faster.

7. Suppose a disk has the following characteristics

- 4 Surfaces
-1024 Tracks per surface
-128 Sectors per track
-512 bytes/sector
-Track-to-track seek time of 5 milliseconds
-Rotational speed of 500 RPM

a. What is the capacity of the drive?

b. What is the access time?

8. Suppose a disk has the following characteristics

- 5 Surfaces
-1024 Tracks per surface
-256 Sectors per track
-512 bytes/sector
-Track-to-track seek time of 8 milliseconds
-Rotational speed of 7500 RPM

a. What is the capacity of the drive?

b. What is the access time?

9. Suppose a disk has the following characteristics

- 6 Surfaces
-16,383 Tracks per surface
-63 Sectors per track
-512 bytes/sector
-Track-to-track seek time of 8.5 milliseconds
-Rotational speed of 7200 RPM

a. What is the capacity of the drive?

b. What is the access time?
