What is HTTP?
HTTP (Hypertext Transfer Protocol) is the method used to connect to web servers on the internet or on a local network, called an intranet
. This connection sends web pages from the server to the user's browser. It can also send and download data from the web server to the user's browser or an application.
How Does HTTP Work?
When you enter a website name (URL) in your browser or click a website link, your browser immediately sends a request to a web server. Your request travels
over the internet or local network to find and deliver the website to you.
How is HTTPS Different Than HTTP?
HTTPS is the secure version of HTTP. When a connection is requested, the session is managed by a security protocol
such as TLS
. This security layer creates end-to-end encryption
for the entire request.
HTTPS is the protocol that should be implemented on all websites today. Without this level of encryption, data passing between your website request and the web pages returned to your browser is easily intercepted by hackers. Always look for the green lock and https:// when you arrive at a website. If the website isn't secure, then do not continue.
What is a Protocol in Technology?
A protocol is an established set of rules that are followed for specific procedures or tasks. For example, a security protocol's job is to ensure that data is transmitted across networks protected against unauthorized users' access.
