Suppose P1,P2,P3 all execute line 1. P1 and ... So processes P1 and P2 can keep on running one after the other without giving the chance to P3 to get a lock on S2. Am I thinking this straight?

SELF DOUBT IN COMPUTER NETWORKS
i came across questions of fragmentation. sir i get really confused when in the question its given that message size is 1000B now should we subtract header from it and then send 980B to the other part or should we take 1000B whole ... cases in which we need to subtract header and transfer and the cases in which we directly transfer without subtracting header length.

MADE EASY: FRAGMENTATION
In the given network, station $A$ wish to sends a payload of $1600B$ from its $network$ $layer$ to station $B$. If fragmentation is done then, the actual data size to be transmitted is? My approach, the first network has an MTU of $1500B$ therefore ... arrive at $B$ and each has a header of $20B$, so total data size is $1700B$ Is my understanding and explanation correct?
