Sab say pehlay main ap k dosray sawal ka jawab dena chahonga...ap nay pocha k source sirf 3 segments hi kyun send karay ga....jawab is ka ye hay k ye depend karta hay k jo network application banaye gae hay us main window size kitna rakha gaya hay...agar wo 3 rakha gaya hay to at a time 3 segments send karay ga source jesa k example main send kia ja raha hay...agar window size 5 rakha gaya hay to 5 segments send hongay...Is k ilawa during communication ye window size kam aor ziada bhi ho sakta hay...misal communication jesay hi start hoi to window size 5 tha liken kuch hi dair k bad source ko pata chal jata hay k destination 5 segments recieve nahi kar paraha kisi waja say,ho sakta hay destination ki speed slow ho ya rastay main network per congestion ziada ho to is case main window size 5 say kam ho kar 4 yh 3 bhi ho sakta hay...lehaza window size fix nahi hota....ap ka pehla sawal tha k ack 2 jab destination nay send kia to sender nay segment 2 hi kyun send kia to baat yahan clear hay k destination ko segment number 2 nahi mila baki k 1 and 3 mil gae...to wo ACK 2 send karay ga source ko takay source aglay 3 segments main segments number 2 ko bhi send karay,to source nay aglay segment main segment number 2,4 aor 5 send kiye jesa k figure main dekhaya gaya hay....Mazeed koi sawal ho zaror pochiye ga...Shukriya!

Ji han during HANDSHAKE bohat sari batein share hoti hain source aor destination k darmian jis main ye bat bhi decide hojati hay k source ki window size kia hogi...us k bad ye window size kam ya ziada bhi ho sakti jisay ham kehtay hain "SLIDING WINDOW"...
