m1)Explain the evolution of industrial automation from DCS and SCADA to IoT and System-ofSystems (SoS). Highlight major limitations and advancements.? Evolution of Industrial Automation:: 1. DCS and SCADA (Earlier systems) Used for monitoring and controlling machines inside a plant, Worked in a fixed, hierarchical structure, Systems were vendor-specific and tightly connected, Hard to integrate with other systems , Not flexible for frequent changes or expansion , Mostly local systems, not
Definition: The science of collecting, organizing, analyzing, and interpreting numerical data to understand behavior.
Key Points:
Aggregate of Facts: It deals with groups (populations), not single individuals.
Variability: It exists because people are different; if everyone was the same, we wouldn't need it.
Art & Science: It uses mathematical rules (Science) but requires judgment to choose the right test (Art).
Scope: Used in clinical psychology (testing treatments)

In an Oligopoly, firms are interdependent, meaning one firm’s pricing decision directly affects others. To avoid destructive price wars, firms often adopt a Price Leadership Model, where one firm (the "leader") sets the price, and others (the "followers") match it.
1. Types of Price Leadership -There are three primary forms of price leadership based on how the leader is established:
A. Dominant Firm Price Leadership -A single firm controls a massive share of the market (usually 60–80%), while
Price Elasticity of Demand (PED) is an economic measure that shows how sensitive the quantity demanded of a good is to a change in its price. In simpler terms, it tells us "how much" consumers will reduce or increase their purchases when the price changes.
The law of demand tells us that price and quantity move in opposite directions, but elasticity tells us the magnitude of that move. It is mathematically expressed as:
Methods of Measuring Price Elasticity
While there are several ways to calculate
In economics, a Market Demand Function is the mathematical relationship that shows how the total quantity demanded for a commodity by all consumers in the market is influenced by various factors.1. Definition
The market demand function expresses the functional relationship between the total demand for a good and the factors (determinants) affecting it. It is the horizontal summation of individual demand functions of all consumers in the market.
2. Algebraic Expression
It is typically represented as:
Computer Forensic Services
Computer forensic services involve the professional application of scientific investigation techniques to identify, preserve, extract, and analyze data from digital devices. These services are used to transform raw digital data into "legal evidence" that can be presented in a court of law. For your SPPU exam, remember that these services aren't just about finding files; they focus on maintaining the integrity of data and a strict chain of custody. Typical services include
A sensor is a device that detects, measures, or senses a physical quantity such as temperature, pressure, displacement, light, humidity, flow, etc., and converts it into a usable electrical signal (voltage, current, resistance).
Sensors act as the input element of any measurement or control system.
They form the first stage of data acquisition.
Without sensors, a system cannot perceive real-world
