How does the Internet work? (part 1)

The Internet of Things

The Internet is such a powerful force; it allows us to communicate/recieve information from different parts of the world! It’s just insane and amazing to visualize the different aspects of networking; and how the Internet forever revolutionized our way of seeking information! It all has to do with the hyped up term “ Internet of Things”. The term Internet of Things, or IoT, describes a system of connected devices, appliances, vehicles and digital technologies (and other “things”) that can send data/information without human-to-human or human-to-device interactions. So instead of me walking up to another individual/device in another country to send some info, I can do that using the Internet.

WiFi vs. Internet

I have always used the words WiFi and Internet interchangeably, you don’t even know so many times! But there is a slight difference between these terms. WiFi essentially stands for “wireless networks”, and the Internet is “interconnected networks”. There was a point in time where devices could only be connected through cables to connect from one device to another. It wasn’t too efficient, however, since there was a location limit, and it was kinda inconvenient if you wanted to connect more devices. So essentially what WiFi does is it allows you to connect with devices without cables, in a local area network (like your homes, for example). It does this by using a router, which routes information (in small packets of info) from one device to another.

How is the information transmitted?

So first off, every device on the Internet has some sort of unique identifier, for devices to recognize one another. This is called an IP address. Our laptops, phones, and servers (which are devices that manage/store information) have IP addresses.

Servers down

When you are accessing a website, you are basically sending a HTTP protocol command to the web server in the Internet, to transmit the webpage (that’s why websites start with http!!) Now you know when you were trying to access a website, and for some reason your web browser isn’t processing the request. It often happens when the web server is down and under maintenance. These are some examples of when the server might be facing a technical problem:
