One OS concept worth knowing

User Space → Applications
↓ System Calls
Kernel Space → OS services
↓
Hardware

The kernel is basically the middleman between your applications and the hardware.

And yes… I’m finally making friends with OS 😂

Day 3 : me vs Leetcode SQL 50
Joins are too confusing 🥲
But yes, I’ll be the winner of this war. 😂

[Shreyas Naphad @NaphadShreyas]

IF YOU'RE LEARNING SQL, start with these:

→ SELECT — choose the data you want
→ FROM — choose the table
→ WHERE — filter rows
→ GROUP BY — group rows
→ HAVING — filter groups
→ ORDER BY — sort the results
→ LIMIT — restrict the number of rows
