Shortcut HTTP means HyperText Transfer Protocol. It is a communication protocol that allows the transfer of data between a web server and the user's browser. It allows your browser to retrieve web content, images, videos or other files. HTTP is unsecured protocol, which means that the data is transmitted in open form and can be intercepted or altered during the journey. In the early days of the internet, this was not a major problem, but as more and more services and sensitive data came online, it began to show its weakness and HTTPS has started to replace it, which has several benefits.
