Page Table
In a 32-bit machine we subdivide the virtual address into 4 pieces as follows: 8-bit 4-bit 8-bit 12-bit. We use a 3-level page table, such that the first 8 bits are for the first level and so on. Physical addresses are44 bits and ... data segment of 600K starting at address 0x80000000 and a stack segment of 64K starting at address 0xf0000000 and growing upward (towards higher addresses)?

blind writes
Consider the following schedule $S1$. $S_{1}: R_{1}(C) R_{2}(C) W_{1}(A) W_{2}(A) W_{1}(C) R_{1}(B) R_{2}(B) W_{1}(B) W_{1}(D) W_{2}(B) W_{2}(D) R_{1}(F) W_{3}(E) R_{3}(F)$ Let $'X'$ be the number of 'blind-write' operations in the given schedule and $'z'$ be the number of conflict equivalent serial schedules to $S_{1}$. The value of $X*Z$ is_________.

Aloha
You have two computers, $A$ and $B$, sharing a wireless network in your room. The network runs the slotted Aloha protocol with equal-sized packets. You want $B$ to get twice the throughout over the wireless network as $A$ whenever both nodes are backlogged. You configure $A$ to send packets with ... of $B$ to, in order to achieve your throughout goal? $p/(1+p)$ $p/(1+2p)$ $2p/(1+p)$ $1/2$
