3. As on 31 March, 2018 which of the following is the India's fastest supercomputer? [U.P.P.C.S. (Mains) 2017]

Correct Answer: (c) Pratyush
Solution:

As on 31ˢᵗ March, 2018 Pratyush was India's fastest supercomputer which was unveiled at Pune-based Indian Institute of Tropical Meteorology in January, 2018. The supercomputer has been named as 'Pratyush' meaning sun.

It is providing help to make forecasts regarding monsoon, cyclones, tsunamis, earthquakes, air quality, lighting, fishing. hot and cold waves, flood and drought, etc. At present, AIRAWAT-PSAI (installed at C-DAC, Pune) is India's fastest supercomputer.

In November, 2023 List of TOP 500 supercomputer of the world, its global ranking is 90 while Param Siddhi-Al is the second fastest supercomputer of India with global ranking of 163. Pratyush is now the third fastest supercomputer of India with global ranking of 201.

PARAM Kamrupa is a state-of-the-art supercomputing system, deployed under build approach of National Supercomputing Mission with peak computing power of 838 TFLOPS.

5. Which of the following would be the smallest and fastest computer imitating brain working- [U.P.P.C.S. (Pre) 2000]

Correct Answer: (b) Quantum computer
Solution:

Researchers of Oxford University have been successfully invented 10 billion quantum entanglement in silicon. Entanglement is those pair of equipment which are used to develop a quantum computer.

A superfast quantum computer based on qubits or quantum bits can give lots of possible answers to a single question. The traditional computer is generally based on the binary switch or decibel.

6. Y2K problem relates to: [U.P.P.C.S. (Pre) 2000]

Correct Answer: (c) To find out a suitable replacement when the last two digits of the year become zero.
Solution:

Y2K bug also called Year 2000 bug or Millennium Bug. relates to a problem in the coding of computerized systems that was projected to create havoc in computer and computer networks around the world at the beginning of the year 2000 (in metric measurements K. stands for thousand).

To find out another way for this was really very expensive. It is called Y2K problem.
