TCP is sending data at $\text{1 megabyte per second}$. If the sequence number starts with $92000$, how long does it take before the sequence number goes back to zero?

1. $7295.12$
2. $6295.87$
3. $7592.86$
4. $4294.87$

Sequence no = 32 bit

so total no of possible sequence no $2^{32}$

1M sequence no in 1 second

so $2^{32}$-92000+1 sequence no in $\frac{2^{32}-92000+1}{10^{6}}$ =4294.87
