Q3) Affine Cipher is an example of a Monoalphabetic substitution cipber. The encryption process is substantially mathematical done by using the following formula: C= (P• kl + k2) mod 26. Where kl, k2 are two integers representing the key (selected randomly), C is the ciphertext value, and P is the plaintext value. Where C and P integers with values between O and 25. Write an Octave programme to implement this system, run your programme using the Plaintext: "the quick brown fox jumped over the lazy dog". Show the obtained ciphertext with the selected values of the keys kl & k2. b- Given that the plaintext "s" encrypts to ciphertext "W" and plaintext "x" eacrypts to ciphertext "Z" when encrypted with Affine Cipher, Determine, mathematically, the values

Why? The power of today's computers is really astounding. Is there any evidence to back up the broad use of computers in the educational sector over the course of the previous several decades?

From the workplace to the home to even the domain of robots, computers have penetrated almost every part of human life. Consider the idea that computers may one day run the whole world. Ensure that you include at least TWO advantages and disadvantages of frequent computer usage in your analysis.

Consequently, the following concerns must be addressed: What does the term "scalability" mean in the context of computing, and what specific implications does it entail?
