The HTTP Protocol
Let"s talk about how the HTTP protocol works.
At its very foundation, the mạng internet is made up of two vi xử lý core things: clients và servers.
Any time you click on your browser, you are accessing the mạng internet through a web client. It may be Chrome, Firefox, Safari or mạng internet Explorer.
When you visit a website, you are making a request lớn a web server.
Facebook.com, girbakalim.net, MarthaStewart.com/1525880/marthas-chocolate-chip-cookies, all of these sites have their own home address. It"s called an IP address.
Your home address might be 123 Main Street, New York, NY 10001, & Facebook"s address happens lớn be 18.104.22.168.
Whenever you visit a page on the web, you are requesting a whole bunch of documents from that website"s server. Maybe those documents are HTML, CSS, images, a PDF—whatever it is, the basic relationship stays the same: you (the client), make a request, and the website (the server) responds khổng lồ that request.
The language you are using khổng lồ make these requests is called the HTTP protocol. These protocols are really just standards that everyone on the website has agreed to. Just like English, Spanish và Chinese are all languages that have an understood protocol, HTTP is just a bunch of standards & an understood protocol.
