Technology – MCQ – GK Questions

India's Digital Personal Data Protection (DPDP) Act was enacted in August 2023, establishing a framework for processing digital personal data with consent and accountability.

India's National Data Governance Framework Policy aims to facilitate sharing of government and private data to foster AI research and innovation within India.

Musk stated that if compute gets 'super tight,' SpaceX might need the resources back. This flexibility clause ensures SpaceX can prioritize its own computational needs during periods of high demand while still providing Anthropic a reasonable exit strategy.

Elon Musk confirmed that SpaceX agreed to a six-month lease of its Colossus AI infrastructure to Anthropic. This arrangement includes provisions for a reasonable off-ramp, indicating SpaceX may reclaim the compute resources if needed.

Ambassador Sergio Gor indicated that the U.S. is recalibrating its export control policy, which could facilitate enhanced cooperation between India and the U.S. in high-technology areas such as semiconductors, defence technology, and emerging tech domains.

Ambassador Sergio Gor hinted that the recalibration of U.S. export control policies could specifically benefit boosting ties between India and the U.S. in high-technology areas. This indicates potential for enhanced cooperation in critical and emerging technologies.

The suspension was scheduled for exactly two hours, from 7 a.m. to 9 a.m. This timing was likely chosen to minimize commuter inconvenience during morning peak hours. Infrastructure maintenance windows are frequently tested in competitive exams.

Namma Metro announced a two-hour service suspension on the Purple Line for May 31, 2026. Such planned maintenance activities are common in metro systems to ensure safety and operational efficiency. Candidates should note dates and durations mentioned in infrastructure-related current affairs.

RAM (Random Access Memory) is volatile memory that loses stored data when power is turned off. Used for temporary storage of actively running programs and data. Non-volatile memories (ROM, EEPROM, Flash) retain data without power, used for firmware, storage, and configuration settings.

WWW (World Wide Web) is an information system where documents and resources are accessed via internet using URLs and hyperlinks. Invented by Tim Berners-Lee in 1989. Web pages are written in HTML, transmitted via HTTP/HTTPS, and displayed by web browsers. Web is a service running on the internet infrastructure.

INSAT and GSAT series communication satellites provide DTH broadcasting, telecommunication, and weather monitoring services. INSAT-4A, GSAT-15, GSAT-24 carry transponders leased to DTH providers like Dish TV, Tata Play. These geostationary satellites ensure continuous coverage over Indian subcontinent.

GPS (Global Positioning System) uses signals from 24+ satellites to determine precise geographic location (latitude, longitude, altitude) anywhere on Earth. Integrated into smartphones for navigation, ride-hailing, fitness tracking. Works outdoors; assisted by Wi-Fi/cell towers indoors for faster acquisition.

Deque (Double-Ended Queue) allows insertion and deletion at both front and rear ends, combining features of stack (LIFO) and queue (FIFO). Implemented using arrays or linked lists. Used in palindrome checking, sliding window problems, and browser history management. Time complexity: O(1) for end operations.

Encryption transforms plaintext into ciphertext using algorithms and keys, ensuring only authorized parties with decryption key can read the data. Protects data at rest (stored) and in transit (transmitted). Hashing is one-way for integrity; encoding (Base64) is not security; compression reduces size.

NFS (National Financial Switch) is NPCI's largest ATM network in India, enabling interoperability so customers can withdraw cash from any bank's ATM using their debit card. Connects over 2.5 lakh ATMs. RuPay is card network, UPI/IMPS are fund transfer systems. NFS handles ATM transaction routing and settlement.

Network Layer (Layer 3) handles logical addressing (IP addresses), routing packets between networks, and path determination. Routers operate at this layer. Data Link (Layer 2) handles MAC addresses and local delivery; Transport (Layer 4) manages end-to-end connections and reliability.

INS Vikrant (IAC-1) is India's first indigenously designed and built aircraft carrier, commissioned in 2022. It incorporates Indian-developed systems including navigation, combat management, and communication. Represents a milestone in India's defense self-reliance (Atmanirbhar Bharat) and technological capability.

2G (specifically GPRS/EDGE enhancements) introduced packet-switched data enabling basic mobile internet, email, and MMS. 1G was analog voice only. 3G brought faster data for video calls and web browsing. 4G enabled HD video streaming and app ecosystems. Each generation built upon previous capabilities.

SSD (Solid State Drive) uses flash memory chips with no moving parts, offering faster boot times, file access, and durability compared to HDDs with spinning platters. SSDs are silent, consume less power, and are resistant to physical shock. Prices have decreased, making SSDs standard in modern devices.

CSRF (Cross-Site Request Forgery) tricks authenticated users into executing unwanted actions on a web application where they're logged in. Attacker exploits trust between browser and site. Prevention: anti-CSRF tokens, SameSite cookies, checking referrer headers. Distinct from XSS which injects malicious scripts.
