Hello.
Hope you are fine.
HTML
Hypertext Mark-up Language, or HTML, is the predominant markup language for web pages. It provides a means to describe a structured document by denoting structural semantics to text such as headings, paragraphs, lists etc. and also some other semantics by denoting text as links, quotes, and other things. It also allows embedded images and objects and interactive forms. It is written in the form of "tags" consisting of elements surrounded by angle brackets, and can embed or load scripting languages such as JavaScript, that can affect the behavior of HTML processors like Web browsers, and Cascading Style Sheets to define the appearance of text, and the layout of block elements - which is encouraged over explicit presentational markup.
URL
In computing, a Uniform Resource Locator (URL) is a type of Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI. In popular language, a URL is also referred to as a Web address.
Hope this helps you . Thank you.
