Ever wonder what HTTP stands for? Hypertext transfer protocol.
Here is the actual definition in tech terms: "The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems.HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is the protocol to exchange or transfer hypertext."
Maybe you already know that a website with just "http" is not secure, but one with "https" is.
Soon, you'll be seeing "http/2." It's here. It will reduce your aggravation from slow-loading pages because it will make loading times faster. There will be greater efficacy between browser and web server. Http/2 is an upgrade.
The biggest upgrade feature is the faster loading times by eliminating the multiple connections method of the former http. Instead just one connection will be used. Don't try to understand this in techy terms; just realize that will make loading times speedier.
The upgrade certainly is not expected to disrupt the old http system. Http/2 is actually already in use by Chrome and Firefox. And everything's going quite dandy thus far. Have you noticed faster loading times lately? That's why. Maybe with this new protocol, there will no longer be truth to that saying, "A watched website never loads."
Are there any drawbacks to the http/2 protocol? Well, it's not compatible with some forms of encryption, but this isn't all bad news because http/2 was designed with better security in mind. We'd all like to see that secure https for all websites one day (though that's a distant, if ever, reality).
In short, http/2 is a big upgrade that should be greatly welcomed. It will surely eliminate the urge to pick up your computer and throw it when a website loads slowly.
