Have you ever stopped and wondered why the internet usually works?
You tap a link, send a message, or start a video — and most of the time, it just… works.
That’s not luck.
And it’s definitely not vibes.
Networks work because devices and software agree to follow a shared set of rules. Every router, switch, server, and laptop behaves itself. No freelancing allowed.
If they didn’t follow rules, networking wouldn’t be “slow” or “a bit buggy.” It would be complete chaos. Your laptop would be screaming into the void while the router pretends it doesn’t exist.
These rules come in the form of standards and protocols, and they’re the reason your devices don’t act like strangers refusing to make eye contact.
What Are Standards?
Standards are universal guidelines that make sure devices built by different companies can still work together peacefully.
They exist so networking doesn’t turn into a reality show.
Imagine if every phone manufacturer decided to use a completely different charging port.
Oh wait — that already happened, and everyone suffered.
Standards prevent that kind of pain in networking.
They define things like how Ethernet cables send data, how Wi-Fi communicates through the air, and how devices are identified on a network. Thanks to standards like IEEE 802.3, IEEE 802.11, and IP addressing, your laptop can connect to a router it’s never met before and still trust it enough to exchange data.
Without standards, networking would just be very expensive hardware sitting around, aggressively ignoring each other.
What Are Protocols?
If standards are the rules of the road, protocols are the driving instructions.
Protocols define how data is formatted, sent, received, and what happens when something goes wrong — because something always goes wrong.
Think of standards as agreeing to speak English.
Protocols decide how the conversation happens.
Who talks first?
How does the message end?
What happens if someone didn’t hear you and says, “Sorry, say that again?”
Protocols like TCP, IP, HTTP, DNS, SMTP, and HTTPS handle all this quietly in the background. Every time you open a website or send an email, they’re working overtime so you don’t have to think about it.
When protocols do their job well, you don’t notice them at all — which is honestly the highest compliment in networking.
How Standards and Protocols Work Together
Let’s say the network is a big party.
Standards are the house rules. Everyone speaks the same language, uses the same doors, and doesn’t randomly shout over others.
Protocols are the step-by-step social instructions. You walk in, say hello, shake hands, and start a conversation instead of just yelling your life story at strangers.
Standards define what’s allowed.
Protocols define how things actually happen.
Together, they make sure devices don’t just connect — they communicate properly, without awkward misunderstandings.
Networking Models
Now here’s the problem: there are a lot of standards and protocols. Enough to overwhelm even motivated learners.
To keep everyone sane, networking models were created.
A networking model breaks networking into layers, with each layer handling a specific responsibility. This way, engineers don’t have to think about everything at once and lose their minds.
It’s like building a house. Architects, electricians, and plumbers all do different jobs, but they follow the same blueprint. In networking, vendors and engineers follow networking models to design systems that actually work in the real world.
The most commonly used model today is the TCP/IP model.
It’s so widely used that your phone, laptop, router, and probably your smart fridge are all quietly running it right now.
