Suppose window size be 16. Only the 8th packet is lost during transmission. Assume the following: • Packet transmission delay be A, timeout interval be B, and round-trip delay be C. • The path is symmetric in terms of delay. • Timeout is greater than the time to send 16 packets plus the round trip time. • The ACK transmission delay is negligible. How much time will it take to send all 16 packets to the receiver by each protocol? Express the equation using notations mentioned here such as A, B, and C.

When you type the pwd command, you notice that your current location on the linux filesystem is the /usr/local directory. answer the following questions, assuming that your current directory is /usr/local for each question. a. which command could you use to change to the /usr directory using an absolute pathname? b. which command could you use to change to the /usr directory using a relative pathname? c. which command could you use to change to the /usr/local/share/info directory using an absolute pathname? d. which command could you use to change to the /usr/local/share/info directory using a relative pathname? e. which command could you use to change to the /etc directory using an absolute pathname? f. which command could you use to change to the /etc directory using a relative pathname?

The value of sin(x) (in radians) can be approximated by the alternating infinite series create a function (prob3_2) that takes inputs of a scalar angle measure (in radians) and the number of approximation terms, n, and estimates sin(x). do not use the sin function in your solution. you may use the factorial function. though this can be done without a loop (more efficiently), your program must use (at least) one. you may find the mod() function useful in solving the problem.
