LECTURE 1: INTRODUCTION & SECURITY CONCEPTS
CIA Triad:
- Confidentiality: Limits access to authorized users. Breach = unauthorized disclosure.
- Integrity: Prevents unauthorized modification. Breach = altered document.
- Availability: Ensures timely access. Breach = DoS attack.
Additional Objectives:
- Authenticity: Verifies data/sender is real and trustworthy
- Accountability: Actions traceable to specific entities
- Non-repudiation: Cannot deny actions (digital signatures)
**Kerckhoffs's Principle:...
drug metabolism is biochemical process that convert drug into metabolites after adulting their solubility or toxicity●The conversion of drug from one chemical to another also called biotransformation AIM: to convert lipid soluble to water soluble polar drug to avoide reabsorption in renal tubules and help in excretion remove the drug form body ●most of the drug are lipid soluble so it can be Excreted out through metabolism but some drugs are hydrophilic are less biotransformed and Excreted

1. Definition A Pooling Layer is a down-sampling layer in a Convolutional Neural Network (CNN) usually placed after a Convolutional Layer.It reduces the spatial dimensions (Width $\times$ Height) of the input feature maps while retaining the most critical structural information.2. Types of Pooling LayersMax Pooling:Extracts the maximum value from the region covered by the sliding filter. Purpose: Captures the most dominant/prominent features like sharp edges and bright pixels.Average Pooling: Computes
STOCKS: A stock is worth what you expect to receive from it in the future, brought back to today’s dollars. With the dividend growth model, that future income is mainly the future dividends. Stock value = present value of future dividends/income. A stock gives you return in two ways: Dividend yield - Money the company pays you while you own the stock. Capital gains yielD - Money you make if the stock price goes up. So: Total Return=Dividend Yield+Capital Gains. Beginning stock price = $50. Ending...

What is Software Engineering?
Software Engineering is the application of engineering principles, methods, and tools to the design, development, testing, deployment, operation, and maintenance of software systems in a systematic, disciplined, and measurable way.
What is a software process / explain the types of process flow.
Linear/sequential-Activities are performed one after another in a fixed order. Each phase must be completed before the next begins.
Iterative-the development process is repeated
# Part 1: Resettlement & Rehabilitation (R&R)
When major infrastructure projects (like dams, highways, or industries) displace communities, they become **Project Affected Persons (PAPs)**. R&R is the framework used to rebuild their lives.
* **Resettlement:** The physical relocation of displaced individuals to a new geographic location, providing housing and basic civic infrastructure (roads, water, electricity).
* **Rehabilitation:** The holistic process of rebuilding a person's socioeconomic
India has a comprehensive framework of environmental laws established to protect natural resources and control pollution. These pieces of legislation give legal authority to regulatory bodies like the **Central Pollution Control Board (CPCB)** and **State Pollution Control Boards (SPCBs)** to enforce environmental standards.
## 1. The Water (Prevention and Control of Pollution) Act, 1974 :::This was India's first major environmental law enacted to deal with a specific pollution crisis. It was prompted
