Inside every CPU:
Billions of transistors.
Inside every transistor:
Just two states.
ON or OFF.
Everything else—
Videos.
Games.
Websites.
Artificial Intelligence.
Comes from those two states.
0 and 1.

How Memory Works ?From Bits to RAM ; The Memory Hierarchy : Registers, Cache, RAM, SSD, Hard Drive
youtube.com/watch?v=qRYWz6…
What happens when you open a browser?
Launch a game?
Watch a YouTube video?
Where does all of that information live while your computer is running?
The answer is memory.
In this video, we explore how computer memory works, starting from simple bits and bytes all the way to modern RAM and memory hierarchies.
Topics covered:
• What is Memory?
• Bits and Bytes
• Memory Cells
• Transistors and RAM
• Random Access Memory (RAM)
• Memory Addresses
• Reading Data from Memory
• Writing Data to Memory
• Volatile vs Non-Volatile Memory
• Why More RAM Improves Performance
• Memory Hierarchy
• CPU Registers
• How the CPU Really Uses Memory
By the end of this video, you will understand how modern computers store and process information, and why memory is one of the most important components in any computer system.

RAM is not storage.
Storage is not memory.
Memory is not cache.
Cache is not registers.
And registers are where the CPU actually works.
Understanding this hierarchy changes how you see computers forever.

Most people use computers every day.
Very few know what happens after they click an icon.
Inside Computing breaks down the hidden layers:
⚡ Electricity
⚙️ Transistors
🧮 Logic Gates
🖥️ CPUs
💾 Memory
🐧 Linux
🌐 Operating Systems
One layer at a time.

"Avoid copying data to maximize performance."
This is standard advice. But in modern high-performance systems, premature optimization against copying can actually destroy your throughput.
Why? Because we often replace copies with Shared State + Locks. And locks are the silent killer of modern CPUs. 🧵👇
When you use a Lock (Mutex), you aren't just waiting. You are triggering:
1. Cache line bouncing (CPU cores fighting for the lock variable)
2. Context switches (TLB flushes, saving registers)
3. Pipeline stalls
A memory copy (memcpy) is sequentially optimized by hardware and blazing fast. A lock causes complete chaos inside the CPU.
This is why modern architectures (like Rust's ownership model or Go's channels) prefer "sharing by communicating" over "communicating by sharing."
Stop fearing memcpy.
Start fearing .lock().
What’s your biggest "performance optimization" that backfired? Let's talk below.

@elonmusk The SpaceX IPO is a massive win for Nvidia because it proves the endless demand for their chips.
English

Looking forward to taking our exciting partnership with Nvidia to the next-level
NVIDIA@nvidia
Huge congratulations to the @SpaceX team on a historic IPO debut. Fueling the next frontier of space and AI. 🌌 NVIDIA's partnership with SpaceX spans nearly a decade, from hand-delivering the world's first #NVIDIADGX-1 supercomputer in 2016 to the custom DGX Spark handoff at Starbase. Together, we've been pushing the boundaries of accelerated computing to help power the future of space exploration.
