Question

A TCP Sender is just about to send a segment of size 100 bytes with sequence number 1234 and ack number 436 in the TCP header. What is the highest sequence number up to and including which this sender has received from the receiver?

Answer 1

The highest sequence number is

1334

Step-by-step explanation:

The sequence number of segment = 1234

The data size = 100 bytes

The highest sequence number will be the sum of the Sequence number of segment and the data size which is = 1234 + 100 = 1334.

Therefore the highest sequence number is 1334.
