Network Architecture
Network architecture is the design or structure of a computer network that defines how computers communicate and share resources with each other.
There are two types of network architecture:
1. Client-Server Architecture
In this architecture, one computer acts as a server and provides services and resources to other computers called clients. The server manages data, security, and other network resources. It is suitable for large organizations.
Example: A bank network where a central

Comparing Power and Control in Ozymandias and London
Both Shelley and Blake present power as destructive when it is abused. In Ozymandias, Shelley describes the ruler’s “sneer of cold command”. The alliteration emphasises Ozymandias’s arrogance and cruelty, suggesting that he believes he has complete control over others. However, the statement “Nothing beside remains” reveals that his power is temporary because time has destroyed his kingdom. Similarly, in London, Blake uses the metaphor “mind-forg’

Electrical Conductivity: Metals vs. Plastics
Why is the electrical conductivity of metals very high while that of plastics is very low?
Metals: Metallic bonding leaves valence electrons delocalised as an “electron sea” (about 1028–1029 electrons/m3). In band theory, the conduction band is partly filled or overlaps the valence band, so there is no energy gap. Electrons move freely under a small field. Conductivity is approximately 106–108 S/m.
Plastics: Atoms are held by strong covalent bonds,

Mental Health and Mental Illness: Definitions, Perspectives, and Stigma
Q1. Define mental health. Explain its key features.
The WHO defines mental health as a state of well-being in which a person realizes their own abilities, copes with the normal stresses of life, works productively and contributes to their community. It is more than the absence of disease.
Key features:
- Emotional well-being: the ability to experience, express and regulate feelings.
- Psychological well-being: self-acceptance, purpose in life, autonomy, positive relationships and personal growth.
- Social
Binary Trees Explained: Structure, Traversals, Hashing and Sorting
1. Explain Binary Tree
A Binary Tree is a non-linear, hierarchical data structure in which each node can have a maximum of two children, traditionally referred to as the left child and the right child.
Core Structural Components
- Root Node: The topmost node of the tree with no parent.
- Leaf Node: A node with no children (degree 0).
- Internal Node: A node containing at least one child.
- Subtree: A tree structure formed by a child node and its descendants.
