Solution: d)

In India, NKN with its multi-gigabit capability aims to connect all universities, research institutions, libraries, laboratories, healthcare and agricultural institutions across the country to address such paradigm shift. The leading mission oriented agencies in the fields of nuclear, space and defence research are also part of NKN. By facilitating the flow of information and knowledge, the network addresses the critical issue of access and creates a new paradigm of collaboration to enrich the research efforts in the country.

Role of NKN:

• Establishing a high-speed backbone connectivity which will enable knowledge and information sharing amongst NKN connected institutes
  • Enabling collaborative research, development and innovation amongst NKN connected institutes
  • Facilitating advanced distance education in specialized fields like engineering, science, medicine etc.
  • Facilitating an ultra-high speed e-governance backbone
  • Facilitating connection between different sectoral networks in the field of research.

Solution: b)

ASTROSAT is India’s first dedicated multi wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe. One of the unique features of ASTROSAT mission is that enables the simultaneous multi-wavelength observations of various astronomical objects with a single satellite.

• ASTROSAT is designed to observe the universe in the Visible, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum simultaneously with the help of its five payloads.
• This mission has put ISRO in a very exclusive club of nations that have space-based observatories. Only the United States, European Space Agency, Japan and Russia have such observatories in space.

• Grapheneis an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. Graphene is one atom thick. It conducts heat and electricity efficiently, and is transparent.
• Graphene is widely used in making solar cells, light-emitting diodes, touch panels and smart windows. Graphene super capacitors serve as energy storage devices with a capacity for faster charging and longer life span than traditional electrolytic batteries.
• Other potential applications of graphene include water filtration and purification, renewable energy, sensors, personalised healthcare and medicine, to name a few.
