ASSIGNMENT #1
1) Amount of data in the box = (1000GB = 1000*109 bytes = 8000*109 bits)
= 8*1012 bits
Speed of Fast Rider = 30km/hr = 8.33m/s
If the Fast Rider analogy is compared to a network link carrying data, we see that
in the case of the Fast Rider,
Assignment 4 Solution
1. Caesar Cipher
k = 20
C = E(P + k) mod (26),
C = Cipher Text,
P = Plain Text
k = shift
I am sending a secret message
i (8 + 20) mod 26 = 2 = c
a (0 + 20) mod 26 = 20 = u
m (12 + 20) mod 26 = 6 = g
