Suppose in a multiprogramming environment, the following C program segment is executed. A process goes into the I/O queue whenever an I/O related operation is performed. Assume that there will always be a context switch whenever a process requests an I/O, and also whenever the process returns from an I/O. The number of times the process will enter the ready queue during its lifetime (not counting the time the process enters the ready queue when it is run initially) is _________ (Answer in integer).
What is the output of the following code fragment?
int x = 24;}

printf("%3d %3d\n", x, x);}
Consider the following C program
The value printed by the given C program is _________ (Answer in integer).
Match the following layers with their corresponding functionalities:
\[ \begin{array}{|c|c|} \hline \textbf{Layer} & \textbf{Functionality} \\ \hline \text{Networking Layer} & \text{Data packet transfer} \\ \text{Transport Layer} & \text{Host-to-host communication} \\ \text{Data Link Layer} & \text{Error detection and correction} \\ \hline \end{array} \]Let \( A \) be a \( 3 \times 3 \) matrix defined as:
\[ A = \begin{bmatrix} 1 & 1 & 1 \\ 1 & 1 & 1 \\ 1 & 1 & -1 \end{bmatrix} \]Find the eigenvalues of \( A^{13} \).
A disk of size 512M bytes is divided into blocks of 64K bytes. A file is stored in the disk using linked allocation. In linked allocation, each data block reserves 4 bytes to store the pointer to the next data block. The link part of the last data block contains a NULL pointer (also of 4 bytes). Suppose a file of 1M bytes needs to be stored in the disk. Assume, 1K = \(2^{10}\) and 1M = \(2^{20}\). The amount of space in bytes that will be wasted due to internal fragmentation is ___________. (Answer in integer)
Three villages P, Q, and R are located in such a way that the distance PQ = 13 km, QR = 14 km, and RP = 15 km, as shown in the figure. A straight road joins Q and R. It is proposed to connect P to this road QR by constructing another road. What is the minimum possible length (in km) of this connecting road?
Note: The figure shown is representative.
