Web development is the work involved in developing a website for the Internet (World Wide Web) or an intranet (a private network). [1] Web development can range from developing a simple single static page of plain text to complex web applications, electronic businesses, and social network services.
It serves as a sanity check and a simple example of installing a software package.

[15] Variations of the "Hello, World!"
For example, WebDNA includes its own embedded database system. Either form of scripting (i.e., CGI or direct execution) can be used to build up complex multi-page sites, but direct execution usually results in less overhead because of the lower number of calls to external interpreters.

In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.
The format of an email address is local-part@domain, where the local-part may be up to 64 octets long and the domain may have a maximum of 255 octets. [5] The formal definitions are in RFC 5322 (sections 3.2.3 and 3.4.1) and RFC 5321—with a more readable form given in the informational RFC 3696 (written by J. Klensin, the author of RFC 5321 [6]) and the associated errata.
Some email address schemes described the path through multiple hosts needed to deliver email. This worked well only if the first host given in the path was sufficiently well known for the sender's system to be able to contact it. UUCP "bang path": reed!percival!bucket!lisag [5] (example on a business card)
