Maharashtra State PSC Model Paper 3

The correct answer is 1 and 2.

• The basic difference between edge computing and cloud computing lies in where the data processing takes place.
  • Cloud computing is when remote servers hosted on the Internet store and process data, rather than local servers or personal computers.
    • The data is sent, stored, and processed at centralized data centers.
    • Hence statement 1 is correct.
  • Edge computing is computing that’s done at or near the source of the data, instead of relying on the cloud at one of a dozen data centers to do all the work.
    • Hence statement 2 is correct.
    • It doesn’t mean the cloud will disappear.
    • It means the cloud is coming to you.
  • Edge computing enables data to be analyzed, processed and transferred at the edge of a network.
    • The idea is to analyze data locally, closer to where it is stored, in real-time without latency, rather than send it far away to a centralized data center.
    • So whether you are streaming a video on Netflix or accessing a library of video games in the cloud, edge computing allows for quicker data processing and content delivery than cloud computing. 
    • Hence statement 3 is not correct.
  • At the moment, the existing Internet of Things (IoT) systems perform all of their computations in the cloud using data centers.
    • ​Hence statement 4 is not correct.
    • Edge computing, on the other hand, essentially manages the massive amounts of data generated by IoT devices by storing and processing data locally.
    • That data doesn’t need to be sent over a network as soon as it processed; only important data is sent, therefore, an edge computing network reduces the amount of data that travels over the network.
