What is the Internet?
The Internet is a place where you can access any resource you can imagine. Everyone uses it, but how does it actually all work? When a user (typically yourself) on a a client side device (Phone, Personal Computer, Laptop) types in a website such as "https://google.com" The request goes from the client side device, to your ISP (Internet Service Provide) these guys are your Comcast, and or Fios, they ensure if your bill is paid that your request actually reaches the frame of wires that sends information and data all throughout the world. Once the reequest reaches the ISP and they verify that you are validated to be requseting anf sending requests, it moves on to the DNS or Domain Name System. The DNS is essentialy a phonebook, in the sense that "Google" is the name that you are calling, and the DNS is the equivalent to Google's phone number if it had a personal one. The DNS is essentially googles phone number, or a more technically accurate term, it would give you Google's IP so you can connect to their servers. Once the request reaches the DNS and you are connected to that specfic IP, the request then finally reaches the Google servers, who hear this request on their server side computers, and send a request, in HTML CSS and JavaScript which all form the webpage that you see. back allowing access to the resources and or page you were trying to access.

How do we stay SAFE on the Internet?
What does staying safe on the Internet even mean? It means taking the proper precautions, and using the right tools to minimize the risk of your data being stolen, or the risk of you being hacked. Everyone uses the Internet nowadays, but hardly anyone knows how to use it safely. There are so mnay ways your data can be taken from you and sold, and some of it is legal. Your own ISP's are most likely selling your data as we speak. Staying safe on the internet is all about staying disguised. VPN's or Virutal Private Networks, are a tool that can be used to trick your ISP into thinking your request is coming from a place youre not in. For example, usually when your request leaves your computer it goes straight to the ISP, which is why they have so much data, but with a VPN your request first becomes encrypted through the tool, and then the request is made on your behalf through this VPN tool, (you could live in Boston, but have the request be made from London.) Which then goes back through all the same sources, (the ISP, DNS, Server) and finally back to you. What this does is it disguises your location, meaning your ISP wont be able to get your data directly, meaning your data wont continue to be tracked and sold. VPN's also protect from malicious attacks from black hat civilians that want to steal any valuable data they can find.
