Chapter 10, Problem 22RQ
Program Plan Intro
Proportional Integral Derivative (PID) control:
- The PID control refers to a feedback control method.
- It performs the combined actions of proportional, integral, and derivative controls.
- It is one of the most widely used process controllers.
- The PID control is used to maintain a process variable within the limits of a specified set point. These process variables can be temperature, flow, level, or speed.
- It also allows the control process operations to take place outside the Central Processing Unit (CPU), which in fact, greatly reduces the additional burden of CPU.

- CBC-Pad is a block cipher mode of operation commonly used in block ciphers. CBC-Pad handles plain text of any length. Padding is used to ensure that the plaintext input is a multiple of the block length. Hence, the ciphertext is longer than the plaintext by at most the size of a single block.Assume that the original plaintext is 556 bytes and the size of a cipher block is 28 bytes. What will be the padding? If the original plaintext is an integer multiple of the block size, will padding still be needed? Why or why not?arrow_forwardAbstract classes & Interfaces (Ch13) 5.
