Answer / priyadarsan.u.s
VSWR is the ratio of terminal(load)impedance(Zr) to the
characteristic impedance (Zo) of a transmission line or a
wave guide.VSWR=(Zr/Zo)(if Zr>Zo) and VSWR=(Zo/Zr) (if
Zo>Zr).Its value varies between 1 and infinity. Its value
says how much the load is matched with the transmission
line.Its value when reaches unity shows perfect match and
there will be no reflections(towards the source).Thus the
transmission line 'act' as a infinitely long one.From the
value of VSWR we can find out how much power is reflected
from or transmitted into the load. ...Now understood ??

A company wants to transmit data over the telephone, but it is concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a program that will encrypt its data so that the data may be transmitted more securely. Your script should read a four digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output XHTML text that displays the encrypted integer.
