Consider the following statements regarding the slow start phase of the TCP congestioncontrol algorithm. Note that cwnd stands for the TCP congestion window and MSS denotesthe Maximum Segment Size.(i) The cwnd increases by 2 MSS on every successful acknowledgment.(ii) The cwnd approximately doubles on every successful acknowledgement.(iii) The cwnd increases by 1 MSS every round trip time.(iv) The cwnd approximately doubles every round trip time.Which one of the following is correct?
Given below are two statements:Statement I: The laws of nature put two fundamental limits on data rate of a channel. The H.Nyquist limit restricts the number of independent samples per second to twice the band-width in a Noiseless channel.Statement II: Shannon's major result about noised channel is that maximum data rate of a channel whose band width is H Hz, and whose signal-to-noise ratio is S/N is given by:Maximum number of bits/sec \(= H \;log_2 \left(1+\frac{S}{N}\right)\) is given by:In the light of the above statements. choose the correct answer from the options given below
