Subject : Science and Technology

1. Consider the following statements regarding “DigiLocker”:

1. It is a flagship initiative of Ministry of Electronics & IT (MeitY) under Digital India program.
2. Documents in DigiLocker system are deemed to be at par with original physical documents.
3. It is a platform to issue/store and digitally verify government documents and certificates.

How many of the above statements is/are correct?

(a) Only one
(b) Only two
(c) All three
(d) None

Answer: (C)

Explanation: DigiLocker is a flagship initiative of MeitY under Digital India program. It is a platform to issue/store and digitally verify government documents and certificates. Documents in DigiLocker system are deemed to be at par with original physical documents under Information Technology Rules, 2016. Digital Locker is aimed at minimizing the usage of physical documents and enabling sharing of e-documents across agencies. Hence, all the statements are correct.

2. The term “MIMO (multiple input, multiple output)” often seen in news is related to which of the following?

(a) Wireless communications
(b) Biotechnology
(c) Power grid technology
(d) Hybrid technology

Answer: (A)

Explanation: MIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors, optimize data speed and improve the capacity of radio transmissions by enabling data to travel over many signal paths at the same time. Hence, option (a) is correct.

3. Which of the following statement is not correct regarding National Super Computing Mission?

(a) PARAM PORUL is a state-of-the-art Supercomputer at NIT Warangal.
(b) PARAM PORUL is based on Direct Contact Liquid Cooling technology.
(c) PARAM Shivay was the first Supercomputer assembled indigenously.
(d) The majority of the components used to build PARAM PORUL have been manufactured and assembled within the country.

Answer: (A)

Explanation: PARAM PORUL is a state-of-the-art Supercomputer at NIT Tiruchirappalli under Phase 2 of the National Supercomputing Mission (NSM). The majority of the components used to build PARAM PORUL have been manufactured and assembled within the country. It is based on Direct Contact Liquid Cooling technology to obtain high-power usage effectiveness and thereby reducing the operational cost. Under NSM, to date 15 supercomputers have been installed across the nation with a computing capacity of 24 petaflops. PARAM Shivay was the first Supercomputer assembled indigenously. Hence, statement (a) is not correct.

4. Consider the following statements regarding “hermit”:

1. It is a new spyware with capability to affect both Android and iOS devices.
2. It is commercial spyware used by governments.

Which of the statements given above is/are correct?

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

Answer: (C)

Explanation: Hermit is a new spyware with the capability to affect both Android and iOS devices. Hermit is a commercial spyware known to be used by governments with victims in Kazakhstan, Italy and northern Syria. Hence, both statements are correct.

5. Consider the following statements regarding “Nuclear Fusion”:

1. It is a process in which splitting of nuclease happens.
2. It takes place in a state of matter called plasma.

Which of the statements given above is/are correct?

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

Answer: (B)

Explanation: Nuclear Fusion is a process by which two light atomic nuclei (for example tritium and deuterium) combine to form a single heavier (Helium) one while releasing massive amounts of energy. Fusion reactions take place in a state of matter called plasma, a hot, charged gas made of positive ions and free-moving electrons with unique properties distinct from solids, liquids, or gases.nce, statement 1 is incorrect.
