Best answer 6 votes 6 votes 4 bit possible window size 16(0,1,2.....,15). but due to ambiguity we left one sequence number. c) is correct. yankur9 answered Jan 6, 2017 selected Aug 8, 2017 by sourav. yankur9 comment Share Follow See all 3 Comments See all 3 3 Comments reply rishu_darkshadow commented Sep 3, 2017 reply Follow Share Sliding window is of two types: '1.) Go Back N 2.) Selective Repeat if we consider here Go Back N, then ans would be 15 as window size= (2^k)-1 i.e. (2^4)-1=16-1=15 but if we consider Selective Repeat then ans would be 8 as window size= 2^(k-1) i.e. 2^(4-1)=2^3=8 so why we considering here only Go Back N only, not Selective Repeat.. ? 2 votes 2 votes yankur9 commented Sep 4, 2017 reply Follow Share actually , they were asking maximum window size 4 votes 4 votes rishu_darkshadow commented Sep 4, 2017 reply Follow Share okk.. :) 0 votes 0 votes Please log in or register to add a comment.
0 votes 0 votes since 4 bit numbering is used so maximum possible value in 4 bits is 2^4 - 1 = 15. so the maximum window size is 15. Prasanjeet Ghosh answered May 23, 2018 Prasanjeet Ghosh comment Share Follow See all 0 reply Please log in or register to add a comment.
