What happens when you type: http://localhost:3000 A debate will automatically set up between your browser and your device operating system

Fourth interpretation means Connect to my own device using Port 3000. I have already taught you port so you should understand

I know you have a question base on what you have been seeing This http://localhost:3000 is thesame as http://127.0.0.1:3000 How do i know? 😂 😂

They convert "localhost" into a special IP address. For IPv4: 127.0.0.1

localhost has an IP Address Computers don't actually understand the word localhost I got you there right 😄😄 Now how will the computer sort this out

Now that you know the definition of localhost It will interest you to know that there's a weird thing that always happen behind the scene let's check it out...

Alright let's go back to localhost Hope you are following?

Hostname vs IP Address IP address identifies where a device is on a network. Hostname gives that device a readable name. You can think of it like: IP address = house address Hostname = person's name

Now how do we differentiate IP address and Hostname If you have been closely following my teachings you would want to ask this question So let me explain

Similarly, instead of identifying a computer only by its IP address e.g 192.168.1.25 it can have a hostname such as "justice-phone" So: Hostname: justice-phone IP address : 192.168.1.25

What Is a Hostname? A hostname is simply a human-readable name given to a device on a network. Think of it as the name of a computer, phone, or server. Imagine a school has 500 students. Instead of saying, Hey, student number 384! You might say, Hey, Daniel! Daniel is a name that is easier for humans to recognize.

Let me quickly bring some lights into this matter of hostname.....

You see when teaching never try to make the mistake of assuming that your listeners understand every details That's why everything i teach you here can be well interpreted by those who are not even in the tech space So take note of this

So logically base on this life examples I gave Localhost is essentially a hostname that refers to your own computer But what is hostname? 🤔

Technically i mean localhost is a special hostname that always means (This very device I'm using) Whether you're on: a phone, a laptop, a desktop, or a server, localhost always points back to that same device that is it never points to another computer.

Let's check this scenario Imagine This... Suppose you live in a big house and one day, you want to send yourself a letter. Instead of sending it through the post office, you simply walk to your own room and hand it to yourself. That's exactly what localhost does. Instead of sending data over the internet, your computer or phone sends it back to itself.

Understanding local host in computer networking What is localhost?

Grab your writing materials and get to class.....

I do take note of little things that can be easily ignored... Y'all should take note of this it is a life hack
