What is HTTP?
HTTP is a protocol for communication between different devices on a network. It is used to send information between different devices, e.g. browser and web server. HTTP is one of the most widely used protocols on the Internet. HTTP works by sending information in the form of different messages. These messages contain different types of information, e.g. information about what to do (a request), information about an error that has occurred (an error message), or information that everything went well (an approval). One of the most common uses of HTTP is when a browser sends a request to a web server to retrieve a web page. Once the web server has received the request, it sends the web page back to the browser. This is always done via HTTP. HTTP is a very simple protocol, and there are several other protocols that work in the same way. These protocols include HTTPS (a secure version of HTTP), FTP (a protocol for sending files between devices), and SMTP (a protocol for sending email).
