Meaning – The term hypertext transfer protocol, refers to the protocol that is used to transfer data over the web. It is an integral part of the internet protocol suite and defines commands and services used for transmitting webpage data.
HTTP uses a server-client model. A client, for example, may be a home computer, laptop, or mobiledevice. The HTTP server is typically a web host running web server software, such as Apache or IIS.
When you enter a website URL into the URL bar of the web browser, the browser sends a request to the respective server. If the URL is valid, then an HTTP code is generated and the website along with all the data is sent to the browser.
Example of usage – “Encrypted HTTP connections take place over HTTPS, an extension of HTTP designed for secure data transmissions.”
