Online video is an a valid example: it’s been around for an outrageously long time, yet at the same time isn’t a part of the guidelines that drive sites. The HTML code behind each site has dependably adapted well to words and pictures, however stays unmindful of motion pictures.
This hasn’t prevented us from going on the web and watching recordings on sites; program modules exist to handle normal video arrangements, and programs begin them up each time you arrive on a page with video content.
Utilizing modules to handle content that HTML and programs alone can’t is basic and brisk. The issue is, each video arrange “family” needs its own sort of module, and each module should be created for every kind of program.
In light of this, there are zero ensures that a required module will as of now be introduced when seeing a page with video on any given PC and program mix. What’s more, since video substance is taken care of by a different module running inside the program (a program inside a program), it requires extra assets like memory and processor time, and is a regular wellspring of similarity issues (frequently making programs solidify or to crash).
