Business Strategy: Value Chain, Five Forces & E-commerce
What Is Porter’s Value Chain Model?
It is a strategic business tool introduced by Michael Porter.
It helps a company analyze its internal activities to see how it creates value for its customers.
The “value” is the amount customers are willing to pay for a product or service.
The goal is to identify activities where the company can reduce costs or add more value (differentiation) to gain a competitive advantage.
The model splits a company’s activities into two categories: Primary Activities and Support
Geothermal Energy: Sources, Fields and Practical Uses
Geothermal Energy: Heat Within the Earth
Geothermal energy is the heat energy stored within the Earth. This heat originates mainly from:
- Residual heat from the Earth’s formation
- Heat generated by radioactive decay of elements like uranium, thorium, and potassium
Geothermal energy can be harnessed for electricity generation, space heating, industrial processes, and direct heating applications. It is considered a renewable, reliable, and environmentally friendly energy source.
2. Nature of Geothermal

Descriptive Statistics
Descriptive statistics is a branch of statistics used to summarize, organize, and describe the main features of a dataset. It helps in understanding data using numerical measures like mean, median, mode, variance, and standard deviation.
1. Mean
- Mean is the average value of a dataset.
- It is calculated by dividing the sum of all observations by the total number of observations.
- It gives a general idea about the overall data value.
- Formula: Mean = (Sum of all values) / (Number of

Number System Basics and Computer Use
(a) What is a Number System?
A number system is a way of representing numbers using a set of symbols and a base (radix). Examples include:
- Decimal (base 10)
- Binary (base 2)
- Octal (base 8)
- Hexadecimal (base 16)
b) Why Digital Computers Use Binary Number System?
Digital computers use binary because:
- Electronic circuits have two states: ON (1) and OFF (0).
- Binary is reliable and easy to implement.
- It results in less error in data processing.
(c) Convert (1001.0010)₂ to Decimal

Octopuses have an amazing body design, enabling them to defend themselves in a variety of ways. Their primary defense strategy relies on mobility and evasion.
Evasion and Jet Propulsion
The most common defense is flight, utilizing jet propulsion to quickly move through the water. Their flexible body, lacking bones, allows them to escape into small cracks, rocks, crevices, and even discarded items like bottles and cans found on the seafloor.
The Disorienting Ink Cloud
Octopuses are well known for their

Le Corbusier’s Modern Urbanism: Open Block Construction
Le Corbusier’s modern urbanism proposed raising building blocks on pilotis (pillars), seeking continuity by converting previously impassable areas into zones where people could move freely, complemented by numerous gardens. This was achieved by vacating the ground floor, leaving only the supporting pillars.
This new proposal created distinct spaces, separating road traffic from pedestrian traffic. This type of structure is known as open block

The Value of Independence and Saving
- In other European countries, children learn to manage without the help of their parents at a younger age so that they can learn to deal with daily problems independently.
- When I started making my living as a journalist, my parents advised me to save money for a rainy day, but I preferred not to listen to them, so I am now in the red.
