Go to Discussion

CUET PG MCA Previous Year PYQCUET PG MCA CUET 2024 PYQ

Solution

To determine the number of bits required to represent the virtual address space:

Number of pages = 1K = $2^10$ .
Page size = 2 KB = $2^{11}$ bytes.
Virtual address space = Number of pages × Page size = $2^{10}×2^{11}=2^{21}$ bytes.
Bits required =21 bits.

Solution

Flash Memory (A):
- Flash memory is a type of non-volatile RAM that retains data even when power is turned off. It is often used in devices like USB drives, SSDs, and memory cards.
PMOS (B):
- PMOS (P-type Metal-Oxide-Semiconductor) is one of the oldest and slowest types of MOSFET technology. It was widely used in early integrated circuits.
NMOS (C):
- NMOS (N-type Metal-Oxide-Semiconductor) is commonly used in large-scale integration (LSI) due to its faster switching speed compared to PMOS.
CMOS (D):
- CMOS (Complementary Metal-Oxide-Semiconductor) is known for its low power consumption because it uses both PMOS and NMOS transistors in a complementary way, reducing static power dissipation.

Solution

Ways to Implement a Priority Queue

The correct answer is:

(A) Arrays, (C) Heap Data Structure, and (D) Linked List

Explanation:

Arrays:
- Unsorted Array: Insertion is O(1), Deletion is O(n).
- Sorted Array: Insertion is O(n), Deletion is O(1).
Heap Data Structure:
- Binary heaps are commonly used for efficient implementation.
- Insertion and Deletion take O(log n) time.
Linked List:
- Can be implemented as sorted or unsorted.
- Efficiency depends on the choice of implementation.

Why not Fibonacci Tree?

Fibonacci trees are not used directly for priority queues. However, Fibonacci heaps (a separate data structure) can implement priority queues efficiently.

Banker's Algorithm Solution

Step 1: Need Matrix

The Need Matrix is calculated as:

Need = Max - Allocation

Process	R1	R2	R3
P1	4	5	2
P2	1	0	1
P3	6	0	0
P4	0	1	0

Step 2: Initial Available Resources

The Available resources at the start are:

R1 = 4
R2 = 4
R3 = 5

Step 3: Evaluate Each Sequence

Sequence (A): P2 → P4 → P1 → P3

P2: Need = [1, 0, 1], Available = [4, 4, 5]. Allocate resources. New Available = [7, 5, 7].
P4: Need = [0, 1, 0], Available = [7, 5, 7]. Allocate resources. New Available = [10, 7, 9].
P1: Need = [4, 5, 2], Available = [10, 7, 9]. Allocate resources. New Available = [14, 8, 11].
P3: Need = [6, 0, 0], Available = [14, 8, 11]. Allocate resources. New Available = [17, 12, 14].

Result: Sequence (A) is valid.

Sequence (B): P2 → P1 → P3 → P4

P2: Need = [1, 0, 1], Available = [4, 4, 5]. Allocate resources. New Available = [7, 5, 7].

Solution

Given: 4/5 of the students are boys, and the rest are girls. 2/5 of boys and 1/4 of girls are absent.

Step-by-Step Solution

Total students = N
Boys: (4/5) × N = 4N/5
Girls: (1/5) × N = N/5
Boys absent: (2/5) × (4N/5) = 8N/25
Girls absent: (1/4) × (N/5) = N/20
Boys present: (4N/5 - 8N/25 = 12N/25)
Girls present: (N/5 - N/20 = 3N/20)
Total present = (12N/25 + 3N/20)

Final Calculation

LCM of 25 and 20 is 100:
(12N/25 = 48N/100), (3N/20 = 15N/100)
Total present = (48N/100 + 15N/100 = 63N/100)

Answer: 63/100

Solution

Matching List-I with List-II:

List - I	List - II	Explanation
Critical Region	Mutual Exclusion (IV)	The critical region ensures mutual exclusion, allowing only one process to access a shared resource at a time.
Working Set	Principle of Locality (III)	The working set is a concept used in memory management, based on the principle of locality to predict the set of pages a process is likely to use.
Deadlock	Circular Wait (I)	One of the necessary conditions for a deadlock is circular wait, where processes are waiting for resources held by one another in a circular chain.
Wait/Signal	Condition Variable (II)	The wait and signal operations are synchronization mechanisms associated with condition variables in multi-threaded environments.

Final Answer:

(A) → (IV), (B) → (III), (C) → (I), (D) → (II)

Solution

Given:

Amit cycled 15 km south.
Then turned right (west) and cycled 7 km.
Turned right again (north) and cycled 10 km.
Finally, turned left (west) and cycled 5 km.

Calculation:

Vertical displacement: $15 - 10 = 5 \, \text{km (south)}$
Horizontal displacement: $7 + 5 = 12 \, \text{km (west)}$
Using Pythagoras theorem:
Distance = √(5² + 12²) = √(25 + 144) = √169 = 13 \, \text{km}

Answer:

Amit needs to cycle 13 km to return home.
