Q: 1 A sender wants to compute the checksum for the ASCII text "RPSC". Which of the following is the correct 16-bit checksum (in hexadecimal) for the string "RPSC"? Given that each character's ASCII hexadecimal equivalent ('R' → 0x52, 'P' → 0x50, 'S' → 0x53, 'C' → 0x43).
Option A
A Checksum is a simple method used in data communication to detect errors in transmitted messages. The basic idea is to sum the numerical values of all data units using one’s complement arithmetic (end-around carry) , and then taking the one’s complement of the final sum.
End-around carry means add MSB carry-out back into LSB for one’s-complement addition.
Q: 2 How many times the following C program prints “Hello”?
main()
{
fork();
fork();
printf(“Hello”);
}
Option B
The fork() System Call
The fork() system call in C is used to create a new process by duplicating the existing one.
After a fork() call, there are two processes running the same code, the parent process and the child process. Each process continues execution from the point where the fork() was called. So, if you call fork() multiple times, the number of processes increases exponentially.
There is no loop, and each fork() doubles the number of processes. Hence, total “Hello” prints = 2number of forks
Finally, 22 = 4.
Q: 3 In GSM Architecture, which of the following stores the local copy of the data from the HLR?
Option B
In GSM architecture, the Home Location Register (HLR) is a central database that stores permanent subscriber information, such as the subscriber’s profile, services, and current location. When a subscriber roams into a new area, the Visitor Location Register (VLR) temporarily stores a local copy of the subscriber’s data from the HLR.
Q: 4 A technique called __________ can be used by malicious hackers to steal data or damage the database.
Option A
SQL Injection is a malicious technique in which attackers provide crafted input to SQL queries, tricking the database into executing unintended commands. This can lead to unauthorized data access, modification, or deletion. It is a major security concern for databases connected to web applications.
Q: 5 Three vertices of a regular hexagon are chosen. A triangle is formed with these three chosen vertices. The probability, that this triangle is equilateral, is
Option C
To find the probability that a triangle formed by choosing three vertices of a regular hexagon is equilateral, we proceed step by step.
Step 1: Total number of triangles
A hexagon has 6 vertices. The number of ways to choose any 3 vertices to form a triangle is calculated using combinations:
C(6,3) = 20
So, there are 20 possible triangles in total.
Step 2: Favorable outcomes (Equilateral Triangles)
In a regular hexagon, an equilateral triangle can be formed by choosing every second vertex. Label the vertices as 1, 2, 3, 4, 5, 6 clockwise. The equilateral triangles possible are:
Triangle (1, 3, 5)
Triangle (2, 4, 6)
Thus, there are 2 favorable triangles.
Step 3: Probability
The probability is given by:
P = Favorable outcomes / Total outcomes = 2 / 20 = 1/10
Q: 6 In a paging system with a Translation Lookaside Buffer (TLB), the TLB has a hit ratio of 80%. It takes 20 nanoseconds to search the TLB and 100 nanoseconds to access main memory. What is the effective memory access time?
Option B
Q: 7 Which of the following is not range of frequency band operate in Industrial Scientific and Medical (ISM)?
Option D
Industrial, Scientific, and Medical (ISM) bands are portions of the radio spectrum reserved internationally for non-commercial purposes like industrial heating, medical equipment, and scientific experimentation. Over time, they have also been widely used for unlicensed wireless communication, such as Wi-Fi and Bluetooth.
Q: 8 Which of the following are respectively correlated with reliability, performance, and supportability in context of FURPS developed by Hewlett-Packard, the target software design quality attributes namely functionality, usability, reliability, performance, and supportability?
Option B
The FURPS (Functionality, Usability, Reliability, Performance, Supportability) Model, developed by Hewlett-Packard (HP), is a well-known framework used to classify software quality attributes.
| ATTRIBUTE | MEANING |
|---|---|
| Functionality | Accuracy, correctness, and suitability of the software to perform its intended functions. |
| Usability | Ease of use, learnability, and user-friendliness of the system. |
| Reliability | Mean-Time-To-Failure (MTTF), how long the software runs without failure. A higher MTTF means the system runs longer without failure. |
| Performance | Throughput, Response Time, how efficiently the system performs, including speed and capacity. Throughput measures how many operations or transactions the system can process in a given time. |
| Supportability | Maintainability, ease of making changes, fixing bugs, and updating the system. Maintainability reflects how easily the system can be modified or corrected. |
Q: 9 What is the full form of SDRAM?
Option A
The full form of SDRAM is Synchronous Dynamic Random Access Memory. SDRAM is a type of dynamic RAM that is synchronized with the system clock, meaning it waits for the clock signal to perform read or write operations. This synchronization improves speed and efficiency compared to conventional DRAM.
Additionally, SDRAM can pipeline commands, allowing multiple instructions to be processed simultaneously.
Q: 10 The logical output of EX-NOR gate is:
Option D
The EX-NOR (Exclusive-NOR) gate is the complement of the EX-OR (Exclusive-OR) gate. While an EX-OR gate gives output 1 when the inputs are different, the EX-NOR gate gives output 1 when the inputs are the same that means, both inputs are 0 or both are 1.
| Input A | Input B | Output (A ⊙ B) |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
The Boolean expression for an EX-NOR gate is:
Y=A⊙B = (A⊕B)’ = A.B+A’B’
