Any size $2^{16}$ bytes - size of TCP header $2^{16}$ bytes $1500$ bytes Computer Networks gatecse-2008 easy computer-networks application-layer-protocols isro2016 + – Kathleen 26.9k views answer comment Share Follow Print See 1 comment 1 1 comment reply chetan-naik commented Nov 4, 2024 reply Follow flag Due to MTU limitations, NL has the facility of fragmentation and TL has the facility of segmentation. However from AL perspective, all data is directly sent to the TL and TL takes care of the delivery. 1 1 replyShare Please log in or register to add a comment.
Best answer 82 82 votes OPTION A Its transport layers responsibility to divide data in to fragments/ packets. Application layer need not worry about it.

Min data size:- 46B to 1500B where as frame size is 64B to 1518B. 0 0 replyShare reena_kandari commented Aug 25, 2017 reply Follow flag Application layer: can send any size of data Transport Layer: It is a stream-based protocol,it chunks the data in MSS and add the header.MSS is 1460 and by default 536 byte.packet exceeding MSS aren't fragmented, they are simply discarded.

0 0 votes The correct option is A because if the application layer won't be sent the amount of data given to him then it is not feasible for it to be a part in the TCP model. achand05 answered Sep 7, 2018 achand05 comment Share Follow 0 reply Please log in or register to add a comment.
