Tools change.

Fundamentals compound.

The future belongs to engineers who know both.

Use AI.

But never outsource understanding.

Every few years, a new tool arrives.

People predict the end of expertise.

Then reality happens.

AI is just the latest example.

The engineers who thrive won't fight AI.

They'll combine AI with strong fundamentals.

That's where the leverage is.

25 Networking fundamentals you should know

① Network → devices connected together
② IP Address → device identity on a network
③ MAC Address → hardware identity
④ Router → moves traffic between networks
⑤ Switch → connects devices inside a network
⑥ DNS → converts domain names to IPs
⑦ DHCP → assigns IP addresses automatically
⑧ Subnet → smaller part of a network
⑨ Gateway → exit point to another network
⑩ Firewall → allows or blocks traffic

⑪ Port → entry point for an app/service
⑫ TCP → reliable data delivery
⑬ UDP → faster, less reliable delivery
⑭ HTTP → web communication
⑮ HTTPS → secure web communication
⑯ NAT → private IP to public IP translation
⑰ VPN → secure private connection
⑱ LAN → local network
⑲ WAN → wide area network
⑳ Bandwidth → maximum data capacity

㉑ Latency → delay in communication
㉒ Packet → small unit of data
㉓ Packet Loss → missing data during transfer
㉔ Load Balancer → distributes traffic
㉕ CDN → delivers content faster globally

Networking gets easier when you stop memorizing terms
and start understanding how data moves.

A backup you never restore isn't a backup.

You discover a cron job that runs every minute.

Nobody knows what it does.

Nobody wants to delete it.

It's been running in production for 6 years.

What's your next move?
