(a) U.S.A.
(b) China
(c) Germany
(d) Japan

Correct Answer: (b) China

Solution:Supercomputer 'Magic Cube' has been made by China to know the earth's future and calculate the potential changes to the climate and biological systems. Chinese scientists hope to calculate almost everything in natural earth systems from the formation of clouds to changes in climate in hundreds or thousands of years from now.

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

(a) Digital computer
(b) Quantum computer
(c) Param 10,000
(d) IBM chips

Correct Answer: (b) Quantum computer

Solution:Researchers of Oxford University have successfully invented 10 billion quantum entanglement in silicon. Entanglement is those pairs 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.

44. The President of India inaugurated "PARAM KAMRUPA" supercomputer facility at which of the following IITs? [68th B.P.S.C. (pre) 2022]

(a) Guwahati
(b) Kharagpur
(c) Bombay
(d) More than one of the above
(e) None of the above

Correct Answer: (a) Guwahati

Solution:The President of India, Smt. Droupadi Murmu, inaugurated Supercomputer facility 'PARAM Kamrupa' and laboratory for the design and development of high-power microwave components at IIT Guwahati on 13 October 2022. PARAM Kamrupa is a state-of-the-art supercomputing system, deployed under the build approach of the National Supercomputing Mission with peak computing power of 838 TFLOPS.

45. As on 31st March, 2018 which of the following is the India's fastest supercomputer? [U.P.P.C.S.]

(a) Piyush
(b) Prashant
(c) Pratyush
(d) Pushkar

Correct Answer: (c) Pratyush

Solution:As of 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, earthquake, air quality, lightning, fishing, cold waves, floods, and drought, etc. At present, ARAWAT-PSAI (installed at C-DAC, Pune) is India's fastest supercomputer. In November 2023 List of TOP 500 supercomputers of the world, its global ranking is 90, while Param Siddhi-AI 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 169.

46. Y2K problem relates to: [U.P.P.C.S.(PRE)]

(a) Finding out a solution to control computer virus.
(b) To establish uniformity with the computers operating all over the world.
(c) To find out a suitable replacement of digits of the year before zero.
(d) To make drastic change in the working after an experience of sixty years.

Correct Answer: (c) To find out a suitable replacement of digits of the year before zero.

Solution:Y2K bug, also called Year 2000 bug or Millenium bug, relates to a problem in the coding of computerized systems that was expected to create havoc in computers and networks around the world at the beginning of the year 2000. The programmers used two digits to represent years (e.g., 99 for 1999), and another way for this was very expensive to rectify, hence called Y2K problem.

47. At the end of this century, there will be great difficulty in the use of existing equipments and heavy expenditure perhaps a few computers which will be required to rectify them. They are: [M.P.P.C.S.(PRE)1997]

(a) Computers
(b) T.V. sets
(c) Communication Satellite
(d) Air Conditioners

Correct Answer: (a) Computers

48. W.L.L. Means — [Uttarakhand.U.D.A/L.D.A.(PRE) 2003]

(a) Without lever line
(b) Within local line
(c) Wireless in local loop
(d) Wireless in long line

Correct Answer: (c) Wireless in local loop

Solution:W.L.L. means wireless in local loop. It is a communication system by which B.S.N.L. provides preferable communication services to rural areas in India.

49. Which type of computers are the most widely used? [Uttarakhand P.C.S. (mains) 2007]

(a) Supercomputers
(b) Minicomputers
(c) Mainframe Computers
(d) Microcomputers

Solution:Nowadays, the computers which are mostly used are microcomputers such as desktop computers, game consoles, laptop, notebook, tablet computer, smartphones, palmtop (PDAs) etc. These are types of microcomputers.

50. Which type of computer could be found in a digital watch? [M.P.P.C.S. (PRE) 2013]

(a) Mainframe
(b) Supercomputer
(c) Notebook computer
(d) Embedded computer

Correct Answer: (d) Embedded computer

Solution:An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today. Embedded system ranging from portable devices such as digital watches and MP3 players to large stationary installations like traffic lights, factory controllers, and complex systems like hybrid vehicles, MRI, and avionics.
