How does the web work? (PART 1)
As a Developer learning how to program the web, you need to have a clear understanding of how the web works than you likely know now.
This concept will provide you with a wider understanding of the ecosystem in which you are about to embark in or work in.
To add to, it will enable you to talk intelligently with other Developers about your work. To begin with, we are going to know some of the key terms that is used in this field starting with what actually is a Network.
1. Network
When you need two devices communicate together, you either have to link them physically usually with an Ethernet Cable or Wirelessly for example with Wi-Fi or Bluetooth systems. When connected already, you've just created a network for yourself.
2. What is the Internetâ
The internet is simply the backbone of the web, the technical infrastructure that makes the web possible. At its most basic, the internet is a large network of computers that communicates together anytime and anywhere you are in the world.
3. What is an IP addressâ
An IP address is a unique address that is given to a computer that is linked to a network (where IP stands for Internet Protocol). An IP address is made up of a series of 4 numbers separated by dots, For example
But anyways you get the point . Before a computer can have access to the internet, it must have it's address if not won't connect to the internet.
That's perfectly fine for computers, but we human beings have a hard time remembering that sort of address. To make things easier, we can alias an IP address with a human readable name called a domain name. For example (at the time of writing; IP addresses can change) google.com is the domain name used on top of the IP address 142.250.190.78. So using the domain name is the easiest way for us to reach a computer over the Internet.
4. What is a Routerâ
A router is a special tiny computer that makes sure that a message sent from a given computer arrives at the right destination computer. More so, to send a message to computer B, computer A must send the message to the router, which in turn forwards the message to computer B and makes sure the message is not delivered to computer C.
