final value of semaphore
There are Three processesP1,P2,P3 sharing a semaphore for synchronizing a variable, Initial value of semaphore is one. Assume that negative value of semaphore tells us how many processes are waiting in queue. Processes access the semphore in following order a. P2 needs to access ... e. P1 exits critical section The final value of semaphore will be 1. 0 2. 1 3. -1 4. -2

Fragmentation
A router with MTU of $1024\text{ bytes}$ has received an IP packet of size $4240 \text{ bytes}$ with an IP header of $20\text{ bytes}$. The value of MF and offset of the $3^{rd}$ fragment is $MF =0$ $OFFSET =125$ $MF =1$ $OFFSET =125$ $MF =1$ $OFFSET =250$ $MF =1$ $OFFSET =375$
