The window is how much the other end is prepared to accept (65535 implies
infinite). (this is bigger than the maximum packet size on every network
I have ever seen)

: and the sequence-number-field (32 bit). Using 16-bit-numbers for sequencing
: and acknowledging could spare 4 byte in each packet.

Sequence measures how much has been sent.

Both of these are measured in octets (8 bit bytes), it is quite reasonable
to expect a TCP link to send more that 64K octets in one session.
