Suppose datagrams are limited to 1,500 bytes (including header) between source Host A and destination Host B. Assuming a 20-byte IP header and a 20-byte TCP header, how many datagrams would be required to send an MP3 consisting of 4 million bytes?

An array of $n$ numbers is given, where $n$ is an even number. The maximum as well as the minimum of these $n$ numbers needs to be determined. Which of the following is TRUE about the number of comparisons needed? At least $2n-c$ comparisons, for some constant $c$ are needed. At most $1.5n-2$ comparisons are needed. At least $n\log_2 n$ comparisons are needed None of the above

Consider an instance of TCP’s Additive Increase Multiplicative Decrease (AIMD) algorithm where the window size at the start of the slow start phase is $2$ MSS and the threshold at the start of the first transmission is $8$ MSS. Assume that a timeout occurs during the fifth transmission. Find the congestion window size at the end of the tenth transmission. $8$ MSS $14$ MSS $7$ MSS $12$ MSS

Consider the following recurrence relation: $T\left(n\right)= \begin{cases} T\left(\frac{n}{k}\right)+ T\left(\frac{3n}{4}\right)+ n & \text{if } n \geq 2 \\ 1& \text{if } n=1 \end{cases}$ Which of the following statements is FALSE? $T(n)$ is $O(n^{3/2})$ when $k=3$. $T(n)$ is $O(n \log n)$ ... $T(n)$ is $O(n \log n)$ when $k=4$. $T(n)$ is $O(n \log n)$ when $k=5$. $T(n)$ is $O(n)$ when $k=5$.

Let $m[0]\ldots m[4]$ be mutexes (binary semaphores) and $P[0]\ldots P[4]$ be processes. Suppose each process $P[i]$ executes the following: wait (m[i]; wait (m(i+1) mod 4]); ........... release (m[i]); release (m(i+1) mod 4]); This could cause Thrashing Deadlock Starvation, but not deadlock None of the above

According to me $n^3$ should be asymptotically greater since $(\log n)!$ is computed like $\log n$ will be a small constant less than $n$ and when I calculate its factorial it will obviously be less than $n^3$.
