Brain-Computer Interfaces (BCIs) can currently enable paralyzed patients to control robotic limbs using thoughts alone.
- True
- False
Answer: True
Invasive BCIs (like Neuralink, Synchron) have enabled paralyzed individuals to control cursors, robotic arms, and communicate via thought in clinical trials. Non-invasive BCIs (EEG) offer limited control. Challenges: signal resolution, surgical risks, and long-term stability. Represents frontier of neurotechnology and assistive devices.

Answer: All of these
Accessibility features combine: Screen Readers (TalkBack, VoiceOver) narrate UI elements, OCR converts images to speech, and Speech Synthesis provides audio feedback. Integrated into Android/iOS for inclusive digital access. Critical for digital inclusion and assistive technology questions under Rights of Persons with Disabilities Act.
The satellite-based system for early warning of cyclones and floods in India is operated by ________.
Answer: IMD / ISRO
IMD (India Meteorological Department) uses INSAT/GSAT satellites, Doppler weather radars, and numerical models for cyclone tracking and flood forecasting. ISRO provides satellite data and infrastructure. Early warnings enable evacuation and disaster preparedness, saving lives and property. Critical for disaster management questions.
India is among the top three countries in terms of 5G network deployment speed as of 2026.
- True
- False
Answer: True
India achieved one of the world's fastest 5G rollouts, covering 300+ cities within 18 months of spectrum auction (2022-2024). Driven by competitive telecom operators, government policy support, and indigenous technology development. Important for telecom infrastructure and digital India questions.
Which Indian mission successfully demonstrated in-orbit docking technology in 2024?
- Gaganyaan-1
- SPADEX
- Aditya-L2
- NISAR
Answer: SPADEX
SPADEX (Space Docking Experiment) successfully demonstrated autonomous rendezvous and docking of two spacecraft in Earth orbit in 2024. Critical technology for future space station modules, satellite servicing, and human spaceflight. Represents India's advancement in complex space operations. Important for ISRO current affairs questions.
The smallest unit of data in a computer that can have a value of 0 or 1 is called a ________.
Answer: bit
Bit (binary digit) is the smallest unit of data in computing, representing either 0 or 1. Eight bits make one byte. All digital information - text, images, audio, video - is ultimately stored and processed as sequences of bits.
HTTP is a secure protocol for transmitting sensitive data like passwords and credit card information.
- True
- False
Answer: False
HTTP (HyperText Transfer Protocol) transmits data in plaintext, making it insecure for sensitive information. HTTPS (HTTP Secure) uses SSL/TLS encryption to protect data in transit. Always use HTTPS for login pages, payments, and personal data.
Which of the following is NOT a feature of UPI?
- 24x7 availability
- Single click two-factor authentication
- Virtual payment address
- Mandatory physical card
Answer: Mandatory physical card
UPI does NOT require a physical card. It uses virtual payment addresses linked to bank accounts. Key features include 24x7 availability, single-click two-factor authentication, instant fund transfer, and support for multiple banks in one app.
The process of verifying a user's identity before granting access to a system is called ________.
Answer: Authentication
Authentication is the process of verifying who a user claims to be, typically using passwords, biometrics, or tokens. It is distinct from authorization (what an authenticated user is allowed to do) and accounting (tracking user activities).
Which ISRO mission is designed to study the Sun?
- Chandrayaan-3
- Mangalyaan-2
- Aditya-L1
- Gaganyaan
Answer: Aditya-L1
Aditya-L1 is India's first dedicated solar mission, positioned at Lagrange Point 1 (L1) to study the Sun's corona, solar emissions, and space weather. Launched in 2023, it carries seven indigenous payloads for comprehensive solar observations.
Artificial General Intelligence (AGI) currently exists and is widely deployed in commercial applications.
- True
- False
Answer: False
AGI (human-level AI that can learn and perform any intellectual task) does not yet exist. Current AI systems are Narrow AI, designed for specific tasks. AGI remains a research goal with significant technical and ethical challenges to overcome.
The full form of 'USB' commonly used for connecting peripherals is ________.
Answer: Universal Serial Bus
USB (Universal Serial Bus) is an industry standard for cables, connectors, and protocols for connection, communication, and power supply between computers and peripheral devices. USB-C is the latest reversible connector standard.
Which key uniquely identifies each record in a database table?
- Foreign Key
- Candidate Key
- Primary Key
- Composite Key
Answer: Primary Key
Primary Key is a column or set of columns that uniquely identifies each row in a table. It cannot contain NULL values and must be unique. Foreign keys establish relationships between tables, while candidate keys are potential primary keys.
Common Service Centres (CSCs) are access points for delivery of essential public utility services in rural India.
- True
