what is HTML5?

what is  HTML5?

The evolution of the latest version of HTML known as HTML5, a set of capabilities that gives web designers and developers the ability to create the next generation of great online applications. Take the HTML5 <video> tag, for example. Video wasn't a major (or, really, any) part of the early web...

Other cool HTML5 features include offline capabilities that let users interact with web apps even when they don't have an internet connection, as well as drag-and-drop capabilities. In Gmail, for instance, easy drag-and-drop allows users to instantly attach a file to an email message by simply dragging the file from the user's desktop computer into the browser window.

HTML5, like the web itself, is in perpetualevolution, based on users' needs and developers' imaginations. As an open standard, HTML5 embodies some of the best aspects of the web: it works everywhere, and on any device with a modern browser. But just as you can only watch HDTV broadcasts on an HD-compatible television, you need to use an up-to-date, HTML5-compatible browser in order to enjoy sites and apps that take advantage of HTML5's features. Thankfully, as an Internet user, you have lots of choice when it comes to web browsers — and unlike TVs, web browsers can be downloaded for free.

What is the Difference Between http and https?

HTTP and HTTPS


  • Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol and with the SSL/TLS protocol.
  • Transport Layer Security (TLS) and Secure Sockets Layer (SSL), both of which encode the data records being exchanged.
  • It will provide encrypted communication and secure identification of a network web server
  • Hypertext Transfer Protocol (http) is a system for transmitting and receiving information across the Internet..
  • Http serves as a request and response procedure that all agents on the Internet follow so that information can be rapidly, easily, and accurately disseminated between servers, which hold information, and clients, who are trying to access it.
  • In many ways, https is identical to http.
When connecting to a site with an invalid certificate, older browsers would present the user with a dialog box asking if they wanted to continue. Newer browsers display a warning across the entire window. Newer browsers also prominently display the site's security information in the address bar.

What is the Difference Between http and https?


  • As opposed to HTTP URLs which begin with "http://" and use port 80 by default ,
  • While HTTPS URLs begin with "https://" and use port 443 by default.

Google gives its app developers more freedom than Apple does, and the Android operating system is available from many more carriers and on many more phones than Apple's iPhone operating system, reports Discovery News.

According to Nielsen, Blackberry still holds the dominant share with 31 percent of the market, though its lead over Apple is declining.

Twenty-eight percent of smartphone owners have Apple iPhones, and 19 percent have Android devices
