Processor takes required files from RAM & Storage. Then Process It.
Step :- 4 (Output)
The selected app opens on the screen.
(This all was done in milliseconds)
Thats why we feel that phone is running smoothly
Important Parts Of Processor
CPU (Central Processing Unit)
This is the main part of processor which handle normal tasks.
GPU (Graphics Processing Unit)
It processes graphics state
Cores
Processors have Cores
• Dual Core
• Quad Core
• Hexa Core
• Octa Core
The more the core the more the best performance of phone
AI Engine / NPU
In modern processors, this is for tasks.
Such As :-
• Camera Improve
• Voice Assistant
• Smart Battery Saving
Strong Processor Benefits
If your processor was strong then :-
• Phone Work Smoothly
• Smooth Gaming
• Better Camera
• Fast Apps Loading
• No Lag
• Better Future Updates

2.0 GHz, 2.4 GHz, 3.0 GHz etc.
The more the optimized and powerful processor the more the good performance. But only by seeing GHz We can't judge Processors.
• Architecture Matters
• Nanometer Technology Matters
• GPU Power Matters
• Good Optimized Software
Thats why latest processor of 2.4 Ghz is sometimes better than 3.0 GHz Old processor.

Why Processor heats
Do you notice Whenever you play games, export videos Or while multitasking processor uses it full power for best performance this is why heat is generated.
Normal heat is common but excessive heating is dangerous.
