Programmable Logic Controller (PLC): PLC is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Control system: The main function of control system is to manage, command, direct, or regulate the behavior of the system with the use of control loops. A feedback controller is used for controlling a process or operation automatically for continuously modulated control. The two different classes of control action are open loop and closed loop.

1. Unsigned Integers If we have an n-digit unsigned numeral dn-1d n-2...do in radix (or base) r, then the value of that numeral is n−1 r² di Σi=0 which is basically saying that instead of a 10's or 100's place we have an r's or r²'s place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down a large number, we typically use the IEC or SI prefixing system: IEC: Ki = 210, Mi = 220, Gi = 230, Ti = 240, Pi = 250, Ei = 260, Zi = 270, Yi = 280; SI: K=103, M = 106, G = 109, T = 10¹², P = 1015, E = 10¹8, Z = 1021, Y = 1024. 1.1 Conversions a.
