Hello Friends. i am a Junior Digital Marketer and i always confused about Web Design and Web Development. so i want to know what is deference between Web Design and Web Development? Please Help me

Design - The look and feel and UX of a site.
Development - The "back end" mechanics of how the site interacts with things like databases, CMS, etc.

Hello my friend.

I feel slightly uneasy with this subject and the fact that you are probably surrounded with people who know more about it, than me (or us). Sometimes it is best to keep the ambivalence of those expressions which evolve and use to convey different meanings according to the environment, the moment that they are used in documents and are even adapted to the intended audience, sometimes. You are the best, if you keep that in mind.

Development and Design are two different things, for sure. However, if you look at how “programs” and how “web-sites” come into existence, then add “web-applications” as a third category, you notice that both expressions can be used alternatively for the same process:

First, there is nothing,
then there is design (and/or architecture)
then there is development
then there is something new.

This is insufficient. When I hold a programming course for people who do not intend to become developers, I do not talk about design. When I talk to an old lady who wants to write documents in HTML and publish them on the web, I do not talk about development. But when I do the exactly same for well-clothed and blow-drought sons and daughters of Siemens-managers, and although they are too dumb to know the difference between an opening and a closing tag, I will call the course Web-Development.

Your signature spam won't be effective because signatures are not seen by search engines. You're welcome.

As a designer and project director, I lay out the specifications, sequence of work, and task breakdown for the developers (and every other professional) who is on the project or who is otherwise tangent to it.

As someone with, now, 35 years' experience in software, I know what the total project needs to be, and can do things to make sure that developers are able to do their job more efficiently. (For instance, software development requires prodigious powers of mental concentration, so I want to make sure that developers can focus on what they're tasked to do, with a minimum of distraction, and so they can encounter as little ambiguity as possible. When they need answers, I make it possible for them to get those answers quickly.

I'm also very much a facilitator. Many different people need to make contributions and inputs to the project, and it all must be in the right way and at the right time, so that "time == money" is not wasted.

Definitely something that he needed to know as a junior digital marketer trying to do work here.

Design would be more "Marketing", IMO.
Dev - write the code that monkeys sell in Marketing.

Ha ha.

A "designer" is really the architect, and sometimes she's actually called that. [i](Most of the really great designers and architects I've seen, by the way, are women ...)

Developers need to be focused on getting "the infernal myriad of exacting(!) details(!!) that(!!!) must(!!!!) be(!!!!!) exactly(!!!!!!) right(!!!!!!!)" ... uhh ... "exactly right."

They do not want there to be any uncertainty about "where does that wall or window go?"

A designer works at a much higher level of abstraction, so to speak, precisely so that the developers won't have to ... because, as developers wrestling with "ones and zeros and unthinking komputenmachines," they can't.

I am sorry, if I did put you on the wrong trail with my completely serious post, above. While design and architecture are important steps in software development, which comprises development of web-applications, web-design came up with the publication of flat HTML via the Web.

And I am certain, that the OP only talks about this kind of design, the one that is becoming practically obsolete, today.

Cheerio.
