Web technology is the tools and techniques which enables two or more computing devices to communicate over a network i.e. Internet. Web Technology consist of two words, the web refers to the World Wide Web generally known as World Wide Web. WWW is the cyber space containing webpages, documents, and any other resources which are identified and located with the help of their URLs. Technology refers to the tools and techniques that makes these resources available on the Web such as, web browsers to view content of web, Programming languages and frameworks for the development of websites, Database to store data at back end, protocols for communicating on the web, multimedia elements etc.

Web development is the process of designing and developing website which are hosted through internet or intranet. The process of developing web can range from developing static page to a complex such as web based application social media sites, E-commerce. Web development includes web design, web content development, client side scripting, server side scripting, web engineering etc. Since, web development consists of several inter-related task which can be accomplish by different types of developer who focuses on different aspect of web creation. 

Server side and client side programming

Client-Side Scripting programming

Client-side scripting is performed to generate a code that can run on the client side i.e (front end) browser without needing the server-side (back end) processing. Basically, client-side scripts are placed inside an HTML document. The client-side scripting can be used to layout the content of the web. For example, when a user makes a request through web browser for a webpage to the server, it just sent the HTML and CSS as plain text, and the browser interprets and renders the content of web in the client end (user). Client-side scripting is designed to run as a scripting language which can be executed by web browser. Front end developer is someone who design and develop client side of a website. Generally. he or she works in user interface (UI) of a website. Front end developer must be at least fluent in three different languages i.e. HTML, CSS, JavaScript whereas, there are several other libraries which can be used for front end development.

Server-Side Scripting programming

Server-side scripting also known as back-end runs on the server where the application is hosted. Server-side is used to serve content depending upon the user request. Back end helps to create dynamic web based application that allows user to interact and communicate with the application. Back end language also helps to connect front end with data base. So that, User can store and retrieve data as per the requirement.  Back-end developer is responsible for server-side programming. Some of the popular server-side (back-end) scripting language are ASP, JavaScript (using SSJS (Server-side JavaScript e.g. node.js), Perl, PHP, Ruby, Python etc.

Client-side scripting and server-side scripting both works along side. The client-side scripting emphasizes making the interface of the web application or website (UI) more appealing and functional. Whereas, server-side scripting emphasizes on data accessing methods, error handling and fast processing etc.

Note: Full-stack developer understand both Front end and back end development process. They can accomplish entire project. Full stack developer must have expertise in client site and server site Scripting language. Moreover, he/she has a great knowledge of integrating database with the application.
