CSV is flat, which means it's rows and columns only. Great for things like an employee list or a product catalog, but it can’t represent relationships (like a customer placing multiple orders).

Think 32-bit CPUs are stuck with 4 GB RAM?
Enter PAE (Physical Address Extension) — a hardware trick that lets 32-bit CPUs use up to 64 GB of RAM by juggling memory pages behind the scenes.
But the real upgrade? Go 64-bit. 🚀

32-bit CPUs can only address 2³² = 4 GB of memory.
Even if you install 8 GB RAM, most of it is wasted.
Why? The CPU just can’t “see” past 4 billion memory slots.
Unless you upgrade to 64-bit, you’re maxed out. 🧠💾

Your CPU doesn’t know what “x = 5 + 10” means.
It just sees binary instructions:
Move 5 to a register
Move 10 to another
Add them
Meaning? That’s all you.

'A' = 65 in ASCII. Why not just make 'a' = 66, 'b' = 67, etc.?
Because ASCII was designed for efficiency, not simplicity.
Uppercase A–Z = 65–90
Lowercase a–z = 97–122
'A' = 01000001
'a' = 01100001
Just flip 1 bit to switch case 🤯

Unicode is a standard that assigns a unique code point to every character — across languages, scripts, and symbols. That’s how computers can store and process strings like "Hello 你好 👋" without getting confused. One system, every character.

What happens if we increase the bits in a byte? 🤔💾
🟢 Larger Data Units 📦 – Each "byte" stores more info, allowing for bigger numbers & precise storage.
🟠 More Complex Processing ⚡ – CPUs & memory are optimized for 8-bit bytes. Changing it means redesigning everything.

What Does 25GB RAM Mean?
RAM is like a workbench. The bigger your bench (25GB RAM), the more projects (tasks) you can work on at once without putting things away. If your workbench is small, you have to keep switching tasks, slowing you down.

Where Does Processing Happen When Memory Sends Instructions?
Memory (RAM) is like a library. It stores books (data), but doesn’t read them. The CPU (brain) asks for a book and reads it.

Why do transistors switch ON and OFF in a CPU/GPU?
Think of transistors like tiny light switches. They turn ON (1) or OFF (0) to create patterns of electricity. These patterns represent numbers, letters, images—everything in a computer.

A bus bottleneck happens when too much data tries to move through a shared communication channel (bus), but the bus can't handle all the traffic efficiently. This slows down performance, just like a traffic jam on a highway.

A CPU has fewer but more powerful cores. It processes tasks sequentially, meaning it handles one task at a time before moving to the next. It’s best for general computing and decision-making, like running an operating system or managing a game.
