If 24 packets are required to transmit the message, the packet size is 2 bytes 1 byte 4 bytes 5 bytes Computer Networks ugcnetcse-jan2017-paper3 computer-networks network-switching + – go_editor asked Jan 31, 2017 recategorized Jun 25, 2022 by Lakshman Bhaiya go_editor 4.7k views answer comment Share Follow See 1 comment See all 1 1 comment reply raja11sep commented Apr 15, 2022 reply Follow Share Total size of the data including header = 3x24 + 48 = 120 Number of packets = 24. So, size of each packet = (120/24)= 5 0 votes 0 votes Please log in or register to add a comment.
Best answer 2 votes 2 votes 24 packet requires to carry 48 byte of data, so each packet carries 48/24=2Bytre of Data now each packet has got 3 byte of Header. So packet size= 2+3=5Byte D is correct answer here Aboveallplayer answered Jan 31, 2017 edited Feb 3, 2017 by Aboveallplayer Aboveallplayer comment Share Follow See all 0 reply Please log in or register to add a comment.
4 votes 4 votes 4) payload in each packet is 48/24=2 Byte and header length is 3 Byte hence packet size is 3+2 Byte=5 Byte Neeraj Chandrakar answered Oct 15, 2017 Neeraj Chandrakar comment Share Follow See all 0 reply Please log in or register to add a comment.
3 votes 3 votes msg size 48 bytes.. packet header 3 bytes.. remaining portion packet data..let be x therefore 3+x is packet size. now 24 packets needed for 48 bytes. so in each packet.. 48/24 = omly 2 bytes of data.. rest is header. so x=2 therefore packet size is 3+2 =5 Option 4 Debasmita Bhoumik answered Jan 28, 2017 Debasmita Bhoumik comment Share Follow See all 0 reply Please log in or register to add a comment.
1 votes 1 votes i think its option D. since packet size cannot be less than 3..as 3 is header size added to each packet.. a) & b) cant be right so for option c) we get packet data size as 1 B----- 1*24=24 B <message size option d) we get packet data size as 2 B -----2*24=48 B =message size Smriti012 answered Jan 31, 2017 Smriti012 comment Share Follow See all 0 reply Please log in or register to add a comment.
