Information Representation
Information representation is the method used by computers to store, process, and transmit data in a form that can be understood by electronic systems. Since computers are digital devices, all information such as numbers, characters, images, and instructions is represented internally using binary digits (0 and 1). These binary values correspond to electrical signals like ON and OFF. Different coding techniques are used to represent various types of information

All living things are made of one or more cells.
The cell is the basic unit of life.
All cells come from pre-existing cells.
Prokaryotic: simple, no nucleus, no membrane-bound organelles (bacteria).
Eukaryotic: complex, have nucleus + organelles (plant & animal cells).
In both plant & animal cells:
Cell membrane – controls entry/exit.
Cytoplasm – holds organelles, reactions happen here.
Nucleus – controls
Inheritance is an OOP concept that allows a class (called the child or subclass) to acquire the properties and behaviors (fields and methods) of another class (called the parent or superclass).
It promotes code reusability, modularity, and hierarchical classification.
The child class can add new features or override existing ones of the parent class.
class Parent {
// fields and methods
}
class Child extends Parent {
// additional fields and methods
}

what is bitcoin? explain bit coin
Bitcoin is the foundational concept that introduced the world to blockchain technology. It is fundamentally a decentralized, peer-to-peer electronic cash system designed to solve the Double-Spending Problem without relying on a trusted third party like a bank. The Bitcoin network operates on a public, immutable ledger (the Bitcoin Blockchain) which chronologically records every transaction. This ledger is secured by the Proof-of-Work (PoW) consensus mechanism, where
Clustering
👉 Firestore = data storage
👉 Clustering = data analysis
Biopsychology = study of biological basis of behaviour
Interdisciplinary: combines psychology, biology, neuroscience, medicine
Focuses on how brain, hormones, and nervous system affect behaviour and cognition
Applications: understanding mental disorders, learning, memory, emotional responses
Example: Studying stress response involves both hormonal and neural mechanisms
Relevance: helps in clinical psychology, neurorehabilitation, pharmacology
