Internet
The Internet is a global network that links the World Wide Web and billions of computers worldwide to one another. It connects billions of computer users worldwide via the standard internet protocol suite (TCP/IP). Optical fiber cables and other wireless and networking technologies are used in its setup. The fastest method for communicating or exchanging data across computers worldwide right now is the Internet.
Internet History
The first functional version of the Internet, known as ARPANET. ARPANET stands for Advanced Research Projects Agency. It was developed in 1960. Its ability to enable numerous computers to operate on a single network was their greatest accomplishment to that point.
Packet switching is the method used by ARPANET to connect several computer systems to a single network. Using the ARPANET, the first message was sent between computers in October 1969. Following that, technology keeps developing.
How Internet Works Step By Step?
Step 1:
A modem or router connects your computer or other device to the internet. You can connect to different networks all across the world with the help of these gadgets. While a modem connects to your Internet Service Provider (ISP), which offers you cable or DSL internet, your router allows many computers to join the same network.
Step 2:
Enter a URL (Uniform Resource Locator), or web address. Every website has a distinct URL that lets your ISP know where you want to go.
Step 3:
Your ISP receives your query and connects to a number of servers, including a DNS (Domain Name Server) and a NAP Server (Network Access Protection) that store and transmit data. Subsequently, your browser uses DNS to find the IP address associated with the domain name you entered into your search engine.
After that, DNS converts the text-based domain name you enter into the browser into an IP address with numbers. Google.com, for instance, changes to 64.233.191.255.
Step 4:
To deliver a copy of the website to the client over TCP/IP, your browser makes a request via the Hypertext Transfer Protocol (HTTP) to the target server.
Step 5:
After approving the request, the server notifies your computer with a "200 OK" response. Next, the browser receives webpage files from the server.
