Indus Valley Civilization – Detailed 16-Mark Answer
The Indus Valley Civilization (IVC), also known as the Harappan Civilization, flourished from 2600 BCE to 1900 BCE along the Indus River and its tributaries in present-day India and Pakistan. It is one of the world’s earliest urban civilizations, known for its scientific city planning, advanced drainage systems, standardized bricks, and organized socio-economic life.
The evolution of human architecture begins in the prehistoric period, mainly divided into the Old Stone Age (Paleolithic Age) and the New Stone Age (Neolithic Age). These phases show the transformation of human lifestyle from nomadic hunter-gatherers to settled agricultural communities, and this shift directly influenced the development of architecture, materials, tools, and settlement planning.
Period: c. 2 million BCE – 10,000 BCE
Lifestyle:...

# Define Distributed System. Write characteristics of distributed system.
Distributed System:
A distributed system is a collection of independent computers that communicate with each other through a network and appear to the users as a single coherent system.
Characteristics:
* Resource sharing – Hardware, software, and data are shared among nodes.
* Concurrency – Multiple processes run simultaneously.
* Scalability – System can grow by adding more nodes.
* Fault tolerance – System continues

The Great Himalayas, also known as the Himadri, form the northernmost and loftiest range of the Himalayan mountain system. They are characterized by their immense height, continuity, and rugged terrain.
1. Structure of the Great Himalayas
The geological structure of the Himadri is a result of the ongoing collision between the Indian and Eurasian tectonic plates.
* Rock Composition: The core of the Great Himalayas is primarily composed of Archaean rocks like granite, gneiss, and schist. These crystalline
