How Programming Works in a Computer System | Geetesh On Live

In this video, we break down the complete journey of a program — from the moment you type your first line of code, all the way down to the electrical signals firing inside your CPU.
We start simple. We go deep. And by the end — you will never look at a running program the same way again.

🔍 Here's what we cover:
→ What a program actually is at the machine level
→ How Compilers and Interpreters translate your code
→ The CPU's Fetch, Decode and Execute cycle — step by step
→ How RAM, Stack and Heap memory work while your program runs
→ What the Operating System does behind the scenes
→ Threads, Concurrency and why Race Conditions crash programs
→ The full end-to-end flow — code to output, nothing skipped

💬 One question for you —
Which part hit different for you?
The CPU cycle? The memory layout? The OS system calls?
