Let $a_{n−1}a_{n−2}...a_0$ and $b_{n−1}b_{n−2}...b_0$ denote the $2's$ complement representation of two integers $A$ and $B$ respectively. Addition of $A$ and $B$ yields a sum $S=s_{n−1}s_{n−2}...s_0.$ The outgoing carry generated at the most ... $\oplus$ denotes the Boolean XOR operation. You may use the Boolean identity: $X+Y=X⊕Y⊕(XY)$ to prove your result.

Consider three relations $R_1(\underline{X},Y,Z), R_2(\underline{M},N,P),$ and $R_3(\underline{N,X})$. The primary keys of the relations are underlined. The relations have $100,30,$ and $400$ tuples, respectively. The space requirements for different attributes ... execution of the join. For, (a), Order could be anything and min. cost =$100*30*400*$total size of all the attributes.

A $64000$-byte message is to be transmitted over a $2$-hop path in a store-and-forward packet-switching network. The network limits packets toa maximum size of $2032$ bytes including a $32$-byte header. The trans-mission lines in the network are error free and have a speed of $50$ ... answer as $1*3*(T_t+T_p) + \;31*T_t$ where $T_t=0.325\; ms$ and $T_p=3.333\; ms$. Please Confirm.
