An individual who is responsible for running and maintaining a website - Regardless of whether or not it is a corporation, organization, or individual. If you are in 'control' of a website then you are a webmaster.
Anyone who knows a little HTML and owns a website of "unique" content thinking of selling it off to Google for millions No thats not me
A person who knows HTML,Javascript,PHP,Xhtml,Dhtml all those stuff.And also one who knows where to get free templates instead of making smashing his brain and making it in photoshop xD.Thats what i think.I am not really a webmaster but i know just the basic places to get scripts and i feel its enough ^_^
Webmaster is usually the person in charge of a company's website. Though they can also be called a Web Developer (usually more scripting based role) or Web Designer (usually more front-end based role). I've also been known as a Technical Web Consultant, Consultant Web Developer, and many many other names, all for pretty much the same role.
A webmaster can handle one company or organization's website mostly they are the ones supervise the whole website
