- 3. WHAT IS WEB DEVELOPMENT ? Web Development usually refers to developing the website for the Internet (World Wide Web) or for an Intranet (Private network). Also known as Web Programming. It is the creation of Dynamic WebApplications. Examples of Web Applications are Social networking sites like Facebook or E-commerce sites likeAmazon, Flipkart,etc. There are two broad division of Web Development – Front-end Development (also called Client-side Development) Back-end Development (also called Server-side Development).
- 4. FRONT END DEVELOPMENT Front end development refers to producing aweb application so that auser can see and interact with them directly . It is also known as Client side development. It focuses on the visual elements of awebsite that auser willinteract with. A front end developer has one general responsibility: to ensurethat website visitors can easily interact with the page.They do this through the combination of design,technology and programming to code a website's appearance, as well as taking care of debugging. The common technologies we can use in front-end development are: HTML CSS JAVASCRIPT
- 5. FRONTEND DEVELOPMENTTECHNOLOGIES HTML was first created by Tim Berners-Lee, starting in 1989. Itstands for Hyper Text MarkupLanguage. Hypertext means thatthe document contains links that allow the reader to jump to other placesin the document. A Markup Language is away thatcomputers speak to eachother to control how text is processed and presented. It describes the structure of aweb pageand consists series of elements. Its elements tells browser how to displaythe content. It’scode is written in Notepad or anytext editor but save it as .htm or .html extension.
- 6. FRONTEND DEVELOPMENT TECHNOLOGIES (CONT..) CSS was first proposed by Hakon Wium Lie on October 10, 1994 atCERN (European Organization for Nuclear Research). Cascading Style Sheets (CSS) describes how HTML elements are to be displayed on screen. CSS saves a lot of work. It can control the layout of multiple web pages allat once. It is also responsible for responsive layouts of a website. It is also written in any text editor but save as .css extension.
- 7. FRONTEND DEVELOPMENT TECHNOLOGIES (CONT..) Javascript was invented by Brendan Eich in 1995. Javascript is the Programming Language for theWeb. Javascript can update and change both HTML and CSS. Javascript is responsible for the Functioning of the website. It is ascripting language that enablesus to create dynamicallyupdating content, control multimedia,animate images, and pretty much everything else. It is also written in any text editor but add the .js extension.

- 9. BACK END DEVELOPMENT Backend development controls what goes on behind the scenes of the web applications. It is also known as server side development. Backend usually consists of three parts: A server AnApplication A Database Users can’tsee how the backend works but this code is what communicates the databaseinformation to the browser. Common Backend development technologies are: SQL PHP
- 10. BACKEND DEVELOPMENTTECHNOLOGIES SQL stands for Structured Query Language. SQL let us access and manipulate databases. SQL becameastandard of theAmerican National Standards Institute (ANSI) in 1986, and of the International Organization for standardization (ISO) in 1987. SQL is adatabaselanguage, it is used for databasecreation, deletion, fetchingrows, and modifying rows,etc. It can retrieve data and executes queries againstthe database. Every website is supported by a database at the backend. Each time a user submits information or searches something in the website, data gets stored and retrived from the database. SQL is the languagefor qurying and storing datain the database.
- 11. BACKEND DEVELOPMENT TECHNOLOGIES (CONT..) PHP is anacronym for “PHP:Hypertext Preprocessor”. PHP is awidely-used, open sourcescripting language. PHP scripts are executed on theserver. PHP is free to download anduse. PHP is aserver side scripting languagethatis embedded in HTML. It is used to managedynamic content, databases, session tracking, evenbuild entire e-commerce sites.
- 12. A web developer is aprogrammer who specializes in the development ofWorldWide Web applications using a client–server model. The applications typically use HTML, CSS and JavaScriptin the client, PHP ,C#, Python, Node.js or Javain the server , and httpfor communications between client and server. Web developers typically do the following: Meet with clients or management to discuss the needs and design of a website. Create and test applications for a website. Write code for the website,using programming languages such as HTML, CSS, etc. Work with other teammembers to determine what information the site will contain. Work with graphics and other designers to determine the website's layout. Integrate graphics,audio,and video into the website. Monitor website traffic. WHO ISA WEB DEVELOPER ?
- 13. TYPES OF WEB DEVELOPER There are 3 kinds of Web Developers – Front End Developer, Back End Developer and, Full Stack Developer. Front-End Developer :-They are responsible for how awebsite looks. They create the site's layout and integrate graphics, applications (such as aretail checkout tool), and other content.They also write web design programs in avariety of computer languages,such as HTML or JavaScript. Back-End Developer :- They are responsible for server-side web application logic and integration of the work front-end developers do. Full-Stack Developer :- A full-stack web developer is aperson who can develop both client and server software.They perform the task of both Front end and Back End Developer.
- 14. HOW A WEBSITE WORKS ? When you type aweb address into your browser: The browser goes to the DNS server,and finds the real address of the server that the website lives on. The browser sends an HTTP request message tothe server , asking it to send acopy of the website to theclient. If the server approves the client's request, the server sends the client a"200 OK" message,which means "Of course you can look at that website! Here it is", and then starts sending the website's files to the browser as a series of small chunks calleddata packets. The browser assembles the Data Packets intoa complete web pageand displays it to you.
- 15. WEB DEVELOPER VS. WEB DESIGNER Web Developer Web Developers are more technical in nature. Web development refers to building user-friendly websites based on client’s specifications. They transform designs into fully functional websites. Web development refers to the functionality of the website on how it works. Languages used are HTML, PHP ,JavaScript,CSS, Python, Ruby,jQueryetc. Web Designer Web Designers are very creative in nature. Web designers are the aesthetic element.
