What is CAD?

Computer- Aided Design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. CAD is sometimes translated as "computer-assisted", "computer-aided drafting", or a similar phrase. Related acronyms are CADD, which stands for "computer-aided design and drafting", CAID for Computer-aided Industrial Design and CAAD, for "computer-aided architectural design". All these terms are essentially synonymous, but there are a few subtle differences in meaning and application.CAD was originally the three letter acronym for "Computer Aided drafting" as in the early days CAD was really a replacement for the traditional drafting board.But now is the term is often interchanged with "Computer Aided Design" to reflect the fact that modern CAD tools do much more than just drafting

How Web Works?

Viewing a web page on the World Wide Web normally begins either by typing the URL of the page into a web browser, or by following a hypertext link to that page or resource. The first step, behind the scenes, is for the server-name part of the URL to be resolved into an IP address by the global, distributed Internet database known as the domain name system, or DNS. The browser then requests the resource by sending an HTTP request to the web server at that IP address. In the case of a typical web page, the HTML text is requested first and parsed by the browser, which then makes additional requests for graphics and any other files that form a part of the page in quick succession.

World Wide Web (www)

The World Wide Web (commonly shortened to the Web) is a system of interlinked, hypertext documents accessed via the Internet. With a web browser, a user views web pages that may contain text, images, videos, and other multimedia and navigates between them using hyperlinks.
