HTTP stands for Hypertext Transfer Protocol. It’s an application-level protocol, that works as a request-response protocol between a client and server over the web. HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links and hyperlinks between nodes containing text.
A Web server is a program that uses HTTP Hypertext Transfer Protocol to serve the files that form Web pages to users, in response to their requests, by HTTP clients. Dedicated computers and appliances may be referred to as Web servers as well. An application server is a software framework that provides both facilities to create web applications and a server environment to run them. It acts as a set of components accessible to the developer through an API defined by the platform itself.
The file is split into small data packets. The client sends a packet to the destination after opening an authenticated connection. FTP server checks the packet, if the data is correct, it sends a request for the next packet, till the file is completely received. Use HTML headings for headings only.

If the form is updating data or includes sensitive information (password), use this method. The POST method offers better security because the submitted data is not visible on the page address. URLs can only be sent over the Internet using the ASCII character set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into ASCII. URL encoding converts characters into a format that can be transmitted over the Internet.
