Question 1 of 10
1. Question
1 pointsConsider the following statements with reference to satellite and transmission based wireless communication:
1.Coverage area of satellite based is greater than that of terrestrial based wireless communication
2.In satellite link delay from earth to satellite is about 240ms while it will be far less for terrestrial link
3.In satellite system the transmission cost depends on the distance within the area of coverage of satellite antenna
Which of the statements given above is/are correct?Correct
Option A is correct answer.
•Statement 1 is correct. Coverage area of a satellite based system is greater than that of a terrestrial based wireless communication system. A GEO satellite with one single antenna can cover about 1/4th of the earth
•Statement 2 is correct and statement 3 is incorrect. In a satellite link delay from earth to satellite to earth is about 240ms while in terrestrial link it will be far less. But transmission cost in a satellite system is independent of the distance within the area of coverage of the satellite antenna, while in terrestrial system it varies based on the distance.Incorrect

Question 2 of 10
2. Question
1 pointsConsider the following statement with reference to Virtual Reality and Augmented reality
1.Augmented reality uses headset to place one in a computer generated world that you can explore
2.Virtual reality uses digital images and layers them over the real world objects
3. With virtual reality, one can explore an underwater environment. With augmented reality, one could see fish swimming through the world around you.
Which of the statements given above is/are incorrect?Correct
Option A is correct answer.
•Virtual reality (VR) and augmented reality (AR) are two technologies that are changing the way we use screens, creating new and exciting interactive experiences.
•Statement 1 and 2 are incorrect Virtual reality uses a headset to place you in a computer-generated world that you can explore. Augmented reality, on the other hand, is a bit different. Instead of transporting you to a virtual world, it takes digital images and layers them on the real world around you through the use of either a clear visor or smartphone.
•Statement 3 is correct.Incorrect

Question 3 of 10
3. Question
1 pointsConsider the following statement regarding Hubble Telescope:
1. It was launched and deployed in space by the space shuttle ‘Discovery’ in 1990.
2. Hubble can detect ultraviolet light, visible light as well as near-infrared
Which of the statements given above is/are correct?Correct
Option C is correct answer.
• Statement 1 is correct. Named in honor of the trailblazing astronomer Edwin Hubble, the Hubble Space Telescope is a large, space-based observatory, which has revolutionized astronomy since its launch and deployment by the space shuttle Discovery in 1990.
• Statement 2 is correct. Telescopes have a particular range of light that they can detect. Hubble’s domain extends from the ultraviolet through the visible (which our eyes see) and into the near-infrared. This range has allowed Hubble to deliver stunning images of stars, galaxies, and other astronomical objects that have inspired people around the world and changed our understanding of the universe.Incorrect

Question 8 of 10
8. Question
1 pointsConsider the following pairs:
(Subject & related terms)
1. Quantum computing: Superimposition
2. Blockchain: Edge Computing
3. Internet of things: Sharding
Which of the pairs given above is/are correctly matched?Correct
Option A is correct answer.
Pair 1 is correct. Pairs 2,3 are incorrect.
Statement 1 is correct. Quantum computers employ the superposition prinicple of quantum physics. According to this principle, superposition allows quantum objects to simultaneously exist in more than one state or location. Together with entanglement and superimposition capabilities, quantum computers can perform complex calculations more efficiently.
Statement 2 is incorrect. Edge computing can be understood as an efficient complement to cloud computing. While cloud computing relies on data uploaded on a central cloud, edge computing allows advanced on-device processing.
Edge computing moves some portion of storage and compute resources out of the central data centre and closer to the source of the data itself, thereby providing the requisite speed and efficiency in processing. This technology is used extensively in the internet of things environment.
Statement 3 is incorrect. Sharding – dividing a blockchain into several smaller component networks called shards capable of processing transactions in parallel.Incorrect
