For this problem, you will conduct experiments and analyze the results.

a. Write a small C program that copies data from a file A to a file B byte-by-byte. For different file sizes

1MB 128MB (doubling the file size in each step), record the time your program requires to

complete the file copy when using read() and write() system calls. Generate a graph that depicts the

program performance.

b. Repeat this experiment, but instead of copying individual bytes, use larger size portions of the file

that are copied in each read() and write() system call. For instance, you may choose to copy the file in

chunks of 2, 4, 8, , 1024 byte units. Generate a performance graph and interpret your experimental

results. What do you observe? Why do you think the system shows the observed behavior?

You must submit your programs for parts a) and b); the graphs of the corresponding experiments;

and your analysis.
