Web development is the process of building and maintaining a website for
the internet or an intranet that is accessed through a web
browser and hosted on a server, either on on-premises hardware or in
the cloud. This includes everything from single plain-text webpages up to
complex web applications.
3. CODING
Web developers build websites by coding using different programming
languages. These languages consist of unique vocabularies, syntax
and commands that define the visual representation and functionality of
websites. Which language is used for development depends on
the platform, operating system or style of the website.

include the following:
HTML
CSS
JavaScript
Python
C/C++
C#

Communication between clients and servers is done
by requests and responses:
1- A client (a browser) sends an HTTP request to the web

3- The server runs an application to process the request
4- The server returns an HTTP response (output) to the
browser
5- The client (the browser) receives the response

information, graphics, interactive pages and videos on the
Internet. Web browsers also know how to communicate with
web servers that host websites and pages that are transmitted to
computers.
