Technology – Fill in the Blank – GK Questions

Q: The satellite-based system for early warning of cyclones and floods in India is operated by ________.

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.

Q: The smallest unit of data in a computer that can have a value of 0 or 1 is called a ________.

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.

Q: The process of verifying a user's identity before granting access to a system is called ________.

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).

Q: The full form of 'USB' commonly used for connecting peripherals is ________.

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.

Q: The technology that overlays digital information onto the real world through smartphone cameras is called ________ Reality.

Augmented – Augmented Reality (AR) superimposes computer-generated images, sounds, or data onto the real-world environment. Unlike VR which creates fully immersive digital environments, AR enhances reality. Applications include gaming, education, retail, and navigation.

Q: The platform that enables cashless transactions using virtual payment addresses in India is called ________.

UPI – UPI (Unified Payments Interface) enables instant bank-to-bank transactions using virtual payment addresses (e.g., name@bank). Developed by NPCI, it supports peer-to-peer and merchant payments, bill payments, and integrates with multiple banking apps.

Q: A network security system that monitors and controls incoming/outgoing traffic based on predetermined rules is called ________.

Firewall – Firewall is a network security device/software that monitors and filters traffic between trusted internal networks and untrusted external networks based on security rules. It can be hardware-based, software-based, or cloud-based.

Q: The unique address assigned to each device on a network for identification is called ________ Address.

IP – IP (Internet Protocol) Address is a numerical label assigned to each device connected to a network. IPv4 uses 32-bit addresses (e.g., 192.168.1.1), while IPv6 uses 128-bit addresses to accommodate the growing number of internet-connected devices.

Q: The brain of the computer that executes instructions is called ________.

CPU – CPU (Central Processing Unit) is the primary component that executes program instructions, performs calculations, and controls other computer parts. Modern CPUs contain multiple cores for parallel processing and cache memory for faster data access.

Q: The Indian regional navigation satellite system is called ________.

NavIC – NavIC (Navigation with Indian Constellation), formerly IRNSS, is India's independent regional satellite navigation system providing accurate position information over India and 1500 km around. It consists of 7 satellites and is an alternative to GPS.
