Computer networks use packet switching . Packet switching increases the overall throughput , because it is dynamic , unlike circuit switching , which is static and can lead to router flooding(in case many circuit switched networks are using some particular router or routers for fowrarding packets) and which leads to packet dropping by routers leading to decrease in throughput. 0 votes 0 votes OneZero commented Jan 24, 2019 reply Follow Share Yup answer is A. 0 votes 0 votes Please log in or register to add a comment.
1 votes 1 votes Answer: A Advantage of Packet Switching over Circuit Switching : More efficient in terms of bandwidth, since the concept of reserving circuit is not there. Minimal transmission latency. More reliable as destination can detect the missing packet. More fault tolerant because packets may follow different path in case any link is down, Unlike Circuit Switching. Cost effective and comparatively cheaper to implement. for more ref. see this beautiful explanation: https://apposite-tech.com/blog/packet-switching-vs-circuit-switching/ Devwritt answered Jan 24, 2019 Devwritt comment Share Follow See 1 comment See all 1 1 comment reply Rajat Negi commented Jan 24, 2019 reply Follow Share this wasnt asked in the question 0 votes 0 votes Please log in or register to add a comment.

And packet switching increase the throughput in comparison to circuit switching Nbhardwaj answered Jan 25, 2020 Nbhardwaj comment Share Follow See all 0 reply Please log in or register to add a comment.
