HTTP
Http stands for Hyper Text Transfer Protocol. It allows World Wide Web users to transferring information like image, text, video, music, graphic and other files on web pages. Http is basically used to access html pages and also other resources can be accessible using HTTP.
HTTP is a request-response protocol in the client-server computing model. When you enter http:// in front of the address tells the browser to connect over HTTP. For example, when you enter a URL (http://www.abc.com) in your web browser, this sends an HTTP command to the Web server to fetch and transfer the requested web page. Here, your web browser is your client and your website host as a server.
