| Q31➡ | Consider the following two statements: S1: TCP handles both congestion and flow control S2: UDP handles congestion but not flow control Which of the following option is correct with respect to the above statements (S1) and (S2)? Choose the correct answer from the code given below: Code: |
| i ➥ Both S1 and S2 are correct |
| ii ➥ Neither S1 nor S2 is correct |
| iii ➥ S1 is not correct but S2 is correct |
| iv ➥ S1 is correct but S2 is not correct |
