Easy
A Array
B Linked List
C Binary Heap
D None of these
Programming Basics PPSC

Correct Answer: C

A binary heap (min-heap or max-heap) supports priority queue operations (insertion and extraction of priority elements) in efficient O(log n) time.

Q444.Which type of cyberattack involves sending fraudulent emails or messages to trick users into revealing sensitive credentials?

Easy
A Denial of Service (DoS)
B Phishing
C SQL Injection
D None of these
Database Basics PPSC

Correct Answer: B

Phishing is a social engineering attack that mimics legitimate entities to steal credentials, credit card details, or PII.

Q445.In Java programming, what is the primary purpose of defining a constructor?

Easy
A To destroy obsolete objects and free memory
B To initialize a newly created object's state
C To execute loop operations automatically
D None of these
Programming Basics PPSC

Correct Answer: B

A constructor is a special method automatically called when an object is instantiated to set up and initialize its initial parameters.

Q446.What is the worst-case time complexity of a program containing nested for-loops where both loops execute 'N' times?

Easy
A O(N)
B O(N^2)
C O(log N)
D None of these
Programming Basics PPSC

Correct Answer: B

If a loop running N times contains another loop running N times, the inner statements execute N * N = N^2 times, yielding O(N^2) complexity.

Q447.Which neural network architecture serves as the core foundation upon which Large Language Models like ChatGPT are built?

Easy
A Transformer architecture
B Recurrent Neural Network (RNN)
C Convolutional Neural Network (CNN)
D None of these
Common Technical Terms PPSC

Correct Answer: A

ChatGPT is built on the Transformer architecture, which uses self-attention mechanisms to process sequential language data in parallel.

Q448.In digital marketing and business, how is Meta AI commonly utilized?

Easy
A Improving advertising and audience targeting
B Enhancing automatic customer engagement
C Automating large-scale data analysis
D All of the above
Common Technical Terms PPSC

Correct Answer: D

Meta AI is used in business to optimize ad targeting, support AI-driven customer chatbots, and analyze user engagement trends.

Q449.In conversational generative AI models like ChatGPT, Natural Language Processing (NLP) is primarily used for generating ______?

Easy
A Text-based responses
B Video-based edits
C Audio/Music files
D None of these
Common Technical Terms PPSC

Correct Answer: A

NLP allows conversational models to process natural language input and generate coherent, context-aware text-based responses.

Q450.Which category of programming languages is designed to be machine-independent, meaning the code can execute across different hardware types?

Easy
A High-level language
B Low-level language
C Assembly language
D None of these
Programming Basics PPSC

Correct Answer: A

High-level languages (like Python or Java) are abstract and machine-independent. They rely on compilers or interpreters to translate code for specific CPUs.

Q451.Which of the following statements best defines the function of a Compiler?

Easy
A A program that translates high-level source code into machine language all at once before execution
B A tool that translates and executes instructions line-by-line during runtime
C An editor used to compose text files and documents
D None of these
Programming Basics PPSC

Correct Answer: A

A compiler translates the entire high-level program code into an executable machine-language object file (.obj) before the program is executed.

Q452.Which function key is standard across Windows operating systems to refresh active folders, file explorers, or web pages?

Easy
A F1
B F2
C F5
D None of these
Operating Systems PPSC

Correct Answer: C

The F5 function key is the universal shortcut to refresh or reload the active window, folder view, or web page.

Q453.Which of the following is a programming language rather than a computer operating system?

Easy
A Python
B Ubuntu
C Windows
D None of these
Programming Basics PPSC

Correct Answer: A

Python is a high-level interpreted programming language. Ubuntu and Windows are operating systems that manage hardware.

Q454.Which of the following is an enterprise database application rather than antivirus software?

Easy
A Oracle
B Avira
C Avast
D None of these
Database Basics PPSC

Correct Answer: A

Oracle is a major relational database management system (RDBMS). Avira and Avast are well-known antivirus security applications.

Q455.In database and file systems, the duplication of the exact same data fields across multiple independent files is referred to as _____?

Easy
A Data Redundancy
B Data Dependence
C Data Inconsistency
D None of these
Database Basics PPSC

Correct Answer: A

Data redundancy is the unnecessary storage of duplicate data across tables or files, which can waste storage and cause inconsistencies.

Q456.What type of user interface does the MS-DOS operating system utilize?

Easy
A Command Line Interface (CLI)
B Graphical User Interface (GUI)
C Multitasking interface
D None of these
Operating Systems PPSC

Correct Answer: A

MS-DOS is a text-based, single-tasking operating system that requires users to type commands manually at a command prompt.

Q457.Which symbol is standard across most computer programming languages to indicate mathematical multiplication?

Easy
A Caret (^)
B Forward Slash (/)
C Asterisk (*)
D None of these
Programming Basics PPSC

Correct Answer: C

The asterisk (*) represents multiplication in C, C++, Python, Java, and Excel formulas (e.g., 5 * 3).
