Network Fundamentals: Protocols, Streaming, and Reliable Data Transfer
Core Networking Concepts
Circuit Switching Fundamentals
In circuit switching, first maximize the smallest link, then proceed to maximize the subsequent links.
Total Network Delay Components
Total delay is calculated as the sum of:
- Processing/Nodal Delay
- Queue Delay
- Transmission Delay (Trans)
- Propagation Delay (Prop)
Bandwidth-Delay Product (BDP)
The Bandwidth-Delay Product (BDP) represents how much data fits within the “pipe” (where delay is the length and bandwidth is the width). To find the number of pipes,

1. Historical Development of Free Movement of Capital
Free movement of capital developed later and more cautiously than the other economic freedoms because the original Treaty rules were vague and ambiguous. Unlike goods, workers, establishment, and services, capital was not granted immediate liberalization or direct effect. During the 1960s and 1970s, the Court of Justice recognized direct effect for the other freedoms, but capital movements were excluded. Liberalization was meant to happen progressively

- Mission: Defines the company’s purpose and direction.
- Management and Culture: Leadership style, values, communication, and work atmosphere.
- Structure: How the company is organized (departments, hierarchy, coordination).
- Resources: Human, financial, physical, and informational resources.
- Systems
Everyday Lies: How Deception Erodes Trust and Integrity
Lying as a Daily Habit
Lying as a Daily Habit: A Critical Analysis of The Ways We Lie. Lying is such a common practice that it often becomes normalized in everyday life. In her essay The Ways We Lie (1992), Stephanie Ericsson argues that lying is not an isolated act but rather a spectrum of strategies we use to protect ourselves, manipulate others, or avoid conflict. Although many lies are justified as necessary or harmless, every lie carries a cost: it erodes trust, distorts communication, and weakens

Materials Management
1. Meaning of Materials Management
Materials management is the process of planning, purchasing, storing, and controlling materials in an organization to ensure their availability at the right time, in the right quantity, quality, and at the lowest cost. It covers the entire flow of materials from suppliers to the production department and finally to distribution. The main purpose of materials management is to maintain a smooth and uninterrupted production process while avoiding

A
ABC Analysis
Assigns items to groups (A, B, C) based on value and importance.
Example: A = laptops, B = keyboards, C = mouse pads.
Accumulation
Receiving goods from multiple sources.
Example: A DC receives shipments from 10 factories.
Activity-Based Costing (ABC)
Assigns cost based on activities, not departments.
Example: Shipping-heavy customers show higher cost-to-serve.
Allocation
Matching inventory to customer orders.
Example: DC allocates 50 units to a customer order.
Anticipatory Stock
Inventory held

Chapter 2: The Qualitative-Value Problem
1. Commodity – The Starting Point
A commodity = anything made to sell, not for personal use.
Marx studies exchange as a social process, not just a trade of things.
2. Two Sides of a Commodity
- Use Value → Usefulness (satisfies wants).
- Exchange Value → How much it trades for.
Marx focuses on exchange value because it shows social relations in capitalism.
3. Value Comes from Labor
The value of a commodity comes from labor used to produce it.
Labor has two sides:

Impact of the Enlightenment and American Revolution
A. The impact of the Enlightenment and the American Revolution
Enlightenment principles and the American Revolution gave the bourgeoisie new ideas to help them confront absolutism and the stratified state system of society. They proposed new forms of social organisation and government. All of this led to the revolutionary cycle that began in France in 1789.

The economic crisis was the result of a series of poor harvests
Two-Way Slab Design Calculations: Steps and Formulas
Step 1: Design Constants
For M20 & Fe415:
τc max = 1.4 N/mm² (from IS:456 Table 73)
σ = 2.76 (used in moment capacity formula)
Step 2: Effective Span Calculation
Slab Type Check
Cy/Cx = 6/4 = 1.5, which is < 2 → Two-Way Slab Panel
Effective Depth Calculation
Using IS 456 empirical formula:
$$\frac{L}{d} = \text{MF} \times \text{BF}$$
Basic factor (BF) = 26
Modification factor (MF) = 1.3
$$d = \frac{L}{\text{MF} \times \text{BF}} = \frac{6000}{1.3 \times 26} = 177.51 \, \text{mm} \approx 180 \, \
