web operation
- The browser finds the actual address of the server hosting the web page on the DNS server
- The browser sends an HTTP request message to the server to request a copy of the web page to the client.
- After the server agrees to the client request, it returns a 200 message, which is then transmitted to the browser in the form of data packets.
- The browser assembles the packet into a complete web page and presents it to you. (Here http requests and other information transmitted by servers and clients are transmitted by TCP/IP protocol)
