Answer 1

1. Option A: Clustering is the correct answer as they made a cluster of 1700 computers which actually work together for a cause. Thus it is the correct answer.

2. Option B: MUA, mail user agent is the correct answer which is the interface where we actually see and send the emails. Thus this option b, MUA, is the correct answer.

3. Option D: proxy server, these are the servers which are set up in such a way that once a person loads some file it will be stored on these servers and next time if someone goes to get the same file, it will be taken from the proxy servers rather than actual far away location. Thus the option D, Proxy Servers, is the correct answer.
