The Defence Research and Development Organisation (DRDO) is the agency under the Ministry of Defence responsible for India's military research and development.

The exercise aims to strengthen the strategic partnership by enhancing interoperability and sharing operational expertise between the two navies.

The Varuna naval exercise between India and France was initiated in 1993 and was later christened as 'Varuna' in 2001.

Varuna is a long-standing bilateral naval exercise conducted between the Indian Navy and the French Navy.

Shor's algorithm, developed by Peter Shor, is a quantum algorithm for finding the prime factors of an integer. It is famously known for its potential to efficiently break many public-key cryptosystems, such as RSA, which rely on the difficulty of factoring large numbers.

A qubit (quantum bit) is the basic unit of quantum information. Unlike a classical bit which can only be 0 or 1, a qubit can exist in a superposition of both 0 and 1 simultaneously, allowing for exponentially more complex computations.

Quantum computers leverage quantum mechanical phenomena such as superposition (where a qubit can be 0, 1, or both simultaneously) and entanglement (where qubits become linked and share the same fate) to perform computations in ways classical computers cannot.

NISAR is designed to use two different radar frequencies: L-band (provided by NASA) and S-band (provided by ISRO). These dual-frequency capabilities allow it to penetrate vegetation and ice, providing comprehensive data on Earth's surface changes.

The primary objective of the NISAR mission is to observe and measure changes in Earth's land and ice surfaces, including ecosystem disturbances, ice-sheet collapse, and natural hazards like earthquakes and volcanic eruptions, with unprecedented detail.

NISAR stands for NASA-ISRO Synthetic Aperture Radar. It is a joint mission between the U.S. space agency NASA and the Indian Space Research Organisation (ISRO) to measure changes in Earth's surface.
