i) For 4096 bytes 65536 / 4096 = 16 pages(total) text = 32768 / 4096 = 8 pages data = 16386 / 4096 = 5 pages stack = 15870 / 4096 = 4 pages 8+5+4 = 17, the answer is no. ii) For 512 bytes 65536 / 512 = 128 pages(total) text = 32768 / 512 = 64 pages data = 16386 / 512 = 33 pages stack = 15870 / 512 = 31 pages 64+33+31 = 128, the answer is yes.

For access control Ethernet(802.3) uses CSMA/CD. In CSMS/CD collision is resolved by binary backoff algorithm which says if a collision occurs then the stations which involved in collision have to wait $wait = k * Time$ here K is a number chosen from ($0 - 2^n-1$) n is collision number as A has Successfully Transmit 1 packet and B has undergone first collision when A and B collide again for B second collision happened as for A new packets ! collision occurred A can wait between (0 or 1) before retransmission B can wait between (0-3) before retransmission (as it… [...]

$\textrm{Given that:}$ $log_{10}(2^x+x-41)=x(1-log_{10}5)$ $\because log_aa=1$ $\textrm{We can use this property here, $log_{10}10=1$}$ $\implies$ $log_{10}(2^x+x-41)=x(log_{10}10-log_{10}5)$ $\implies$ $log_{10}(2^x+x-41)=x(log_{10}(\frac{10}{5}))$ $(\because log_ax-log_ay=log_a(\frac{x}{y}))$ $\implies$ $log_{10}(2^x+x-41)=x(log_{10}2)$ $\implies$ $log_{10}(2^x+x-41)=log_{10}2^x$ $(\because log_ax^n=n*log_ax)$ $\textrm{compair both side we get:}$ $\implies$ $2^x+x-41=2^x$ $\implies$ $x=41$ $\textrm{Option b is correct.}$ [...]

Difference = 500 5% = 500. 100% = (500 *100)/5 = 10000. 100% is the labeled price. So, TV price = 10000 - 20% of 10000 = 80% of 10000 = 8000. [...]
