A gateway serves as a crucial point of entry and connection between different networks or systems. In computing, it acts as a device or software that facilitates communication by translating protocols, routing data, and providing secure access between, for example, a local network and the internet. This enables seamless data exchange, firewall protection, and enhanced network management, making it an essential component in modern digital infrastructure. Architecturally, a gateway can also refer to a grand entrance or portal, symbolizing transition and access in physical spaces like historic monuments or urban designs.

1. Question: What is the time complexity of binary search algorithm?
Options:
A) O(1)
B) O(n)
C) O(log n)
D) O(n^2)
Answer: C
Explanation: Binary search divides the search interval in half repeatedly, leading to a logarithmic time complexity of O(log n).
2. Question: Which data structure follows the Last In, First Out (LIFO) principle?
Options:
A) Queue
B) Stack
C) Array
D) Linked List
Answer: B
Explanation: A stack operates on the LIFO principle, where the last element added is the first one to be removed.
3. Question: In a binary tree, what is the maximum number of nodes at level k?
Options:
A) 2^k
B) 2^(k-1)
C) k^2
D) k
Answer: A
Explanation: In a binary tree, the maximum number of nodes at level k is 2^k, as each node can have up to two children.
4. Question: What is the primary purpose of an operating system’s kernel?
Options:
A) Manage user applications
B) Handle hardware interactions and resource management
C) Provide a graphical user interface
D) Store data permanently
Answer: B
Explanation: The kernel is the core part of an operating system that manages hardware resources and facilitates communication between software and hardware.
5. Question: Which sorting algorithm has the best average time complexity of O(n log n)?
Options:
A) Bubble Sort
B) Insertion Sort
C) Quick Sort
D) Selection Sort
Answer: C
Explanation: Quick Sort typically has an average time complexity of O(n log n) due to its divide-and-conquer approach.
6. Question: What does SQL stand for?
Options:
A) Structured Query Language
B) Simple Query Language
C) System Query Language
D) Sequential Query Language
Answer: A
Explanation: SQL is an acronym for Structured Query Language, used for managing and manipulating databases.
7. Question: In networking, what is the function of a router?
Options:
A) Connect devices within a local network
B) Forward data packets between different networks
C) Store data temporarily
D) Provide wireless connectivity
Answer: B
Explanation: A router forwards data packets from one network to another, based on IP addresses.
8. Question: Which of the following is not a type of operating system scheduler?
Options:
A) Long-term scheduler
B) Short-term scheduler
C) Medium-term scheduler
D) Infinite-term scheduler
Answer: D
Explanation: Operating systems typically have long-term, short-term, and medium-term schedulers, but infinite-term scheduler does not exist.
9. Question: What is the output of the logical AND operation for inputs (True, False)?
Options:
A) True
B) False
C) Undefined
D) Error
Answer: B
Explanation: In logical AND, the result is True only if both inputs are True; otherwise, it is False.
10. Question: Which protocol is used for secure communication over the internet?
Options:
A) HTTP
B) FTP
C) HTTPS
D) TCP
Answer: C
Explanation: HTTPS (HyperText Transfer Protocol Secure) uses encryption to provide secure communication over a computer network.
11. Question: What is the binary representation of the decimal number 10?
Options:
A) 1010
B) 1100
C) 1001
D) 1110
Answer: A
Explanation: The decimal number 10 in binary is 1010, as it equals 8 + 2 (2^3 + 2^1).
12. Question: In object-oriented programming, what is encapsulation?
Options:
A) Hiding data and methods from other classes
B) Inheriting properties from a parent class
C) Creating multiple objects from one class
D) Overloading functions
Answer: A
Explanation: Encapsulation bundles data and methods that operate on the data within a single unit and restricts direct access to some components.
13. Question: Which of the following is a deadlock prevention technique?
Options:
A) Mutual Exclusion
B) Hold and Wait
C) Resource Allocation Graph
D) Banker’s Algorithm

Explanation: The Banker’s Algorithm is used to prevent deadlocks by ensuring that the system never enters an unsafe state.
14. Question: What is the purpose of primary key in a database table?
Options:
A) To store large amounts of data
B) To uniquely identify each record
C) To index the table
D) To link to another table
