What is HTTP?

HTTP stands for Hyper Text Transfer Protocol. It is invented by Tim Berner . Hyper Text is the type of text that is specially coded with the help of some standard coding language called Hyper Text Markup Language (HTML). HTTP provides a standard between a web browser and a web server to establish communication. It is a set of rules for transferring data from one computer to another. Data such as text, images, and other multimedia files are shared on the World Wide Web. Whenever a web user opens their web browser, the user indirectly uses HTTP. It is an application protocol that is used for distributed, collaborative, hypermedia information systems.

🔴How Does the HTTP Protocol Work?

This means that the HTTP protocol uses a forms of a request and response operational mode. When a client wants to retrieve information, it uses http request to the servers as shown in the following stages. The request is received by the server and in the form of an HTTP response the server returns the data which the client requested or an error message. This takes place over the internet using port 80 by default, to assist in the identification of this protocol it is often referred to as the http or the hip protocol.



HTTP Request

HTTP request is a kind of message a client (in most cases, a web browser) sends to the server demanding some specific resources. It comprises of several elements like the request method (GET, POST and etc. ), the headers and occasionally the body carrying the data. This is the request part where the client outlines a request to the server and what they want.

HTTP Response

Http response is a message sent by the server to the client in response to an Http request. In simple
terms, it has status code that describes the result of a request; header, which is information about
the response; and the body, which is the actual response or an error message.

Characteristics of HTTP

👉HTTP is IP based communication protocol that is used to deliver data from server to client or vice-versa.
👉 Any type of content can be exchanged as long as the server and client are compatible with it. 
👉 It is a request and response protocol based on client and server requirements. 


What is HTTPS?

HTTPS stands for Hyper Text Transfer Protocol Secure. HTTP Secure (HTTPS), could be a combination of the Hypertext Transfer Protocol with the SSL/TLS convention to supply encrypted communication and secure distinguishing proof of an arranged web server. HTTPS is more secure than HTTP because HTTPS is certified by the SSL(Secure Socket Layer). Whatever website you are visiting on the internet, if its URL is HTTP, then that website is not secure.

🔴How Does the HTTPS Protocol Work?

HTTPS can be said to be similar to the HTTP only that it also provides a level of security. It first creates a connection between the client and server over SSL/TLS, which enhances security by encrypting the Client and server communication. When a client makes a request for a resource using the https then the server and the client agree on the encryption keys that will be used in encrypting the data that will be transmitted in that particular session. This makes sure that data being exchanged between them is encrypted and coded hence cannot be intercepted.




Characteristics of HTTPS

👉HTTPS encrypts all message substance, including the HTTP headers and the
request/response data. The verification perspective of HTTPS requires a trusted third party
to sign server-side digital certificates.

👉 HTTPS is presently utilized more frequently by web clients than the first non-secure HTTP ,fundamentally to ensure page genuineness on all sorts of websites, secure accounts and to keep client communications.






In short, both of these are protocols using which the information of a particular website is exchanged between the Web Server and Web Browser. But there are some differences between these two. A concise difference between HTTP and HTTPS is that HTTPS is much more secure compared to HTTP.
