What are the differences between HTML and HTML5 ?

The main difference between HTML and HTML 5 is that video and audio are not part of HTML while these both are integral parts of HTML5 specifications.The primary thing you ought to know is that, maybe interestingly, the improvement of a dialect standard is recognizing this present reality. So as to keep document similarity with the present standard – which is, in fact, HTML 4.01 – the bold choice was made to particular the way the web program renders records from the route we, as engineers, must think of them. So the program, or “client specialist”, should even now handle HTML4 develops like the inside component, on the grounds that there will, in any case, a large number of records on the Internet that happen to utilize it. In any case, we won’t compose any more HTML with focus; it’s essentially being dropped from the dialect (use CSS). This similarity goes both ways: more established programs can (and will) basically overlook HTML5 code without botching things. As cool as it is to see what HTML 5 can accomplish for you, it hasn’t been institutionalized like HTML4. You don’t need to stress over overhauling pages assembled utilizing HTML 4. It’s over ten years of age and it’s a set standard. When you hop into HTML5 with both feet, will make overhauls. Components and properties are included and altered a few times each year. Obviously, this is needy the amount you rely on upon rich components, however, it’s absolutely a danger you should mull over when utilizing a liquid dialect. HTML5 is utilized to build up the capacity of the program to be an application stage, by means of HTML, CSS, and Javascript. Numerous components have been added specifically to the dialect that is as of now (in HTML4) Flash or JS-based hacks, for example, <canvas>, <video>, and <audio>. Helpful things, for example, Local Storage (a js-available program worked in key-esteem database, for putting away data past what treats can hold), new info sorts, for example, date for which the program can uncover simple client interface (with the goal that we don’t need to utilize our js-based timetable date-pickers), and program upheld structure approval will make creating web applications much less difficult for the engineers, and make them much quicker for the clients (since numerous things will be bolstered locally, as opposed to hacked in by means of javascript). However, HTML4 is still a W3C standard for program applications, it doesn’t completely oblige the changing patterns of the registering business. In this way, HTML5 has been created with the goal to cop-up with these new difficulties in the web industry. HTML5 is more adaptable, powerful and progressed as a contrast with its more established partner.

Key Differences

• Audio and video were not part of previous HTML version specifications, however, both are the integral part of HTML5 specifications.
• Vector graphics is also an integral part of HTML5 such as SVG and canvas while vector graphics is possible in HTML with the help of various technologies such as VML, Silver-light, Flash, etc.
• In HTML, browser cache can be used as temporary storage. In case of HTML5, application cache, web SQL database, and web storage is used.
• HTML doesn’t allows JavaScript to run in web browser, it runs in same thread as browser interface. HTML5 allows JavaScript to run in background that is possible because of JS Web worker API in HTML5.
• HTML works smoothly with all old browsers while most of the modern web browsers have started supporting HTML5 specifications. These browsers include: Firefox, Mozilla, Chrome, Opera, Safari, etc.
