With the popularity and advancements in web technology, it is imperative for every business to have a website and one which is highly functional and visually attractive. The process through which a good website, mobile apps or other similar platforms are created is known as web development. One of the most integral aspects of web development is web programming that is achieved with the help of programming languages.

Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; user interface design UI design ; authoring, including standardised code and proprietary software ; user experience design UX design ; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and if their role involves creating markup then they are also expected to be up to date with web accessibility guidelines.

The Missing Link: An Introduction to Web Development and Programming

In this first article, we look at server-side programming from a high level, answering questions such as "what is it? After reading this article you'll understand the additional power available to websites through server-side coding. Dynamic sites can highlight content that is more relevant based on user preferences and habits. In the modern world of web development, learning about server-side development is highly recommended. The response contains a status line indicating whether or not the request succeeded e.

The body of a successful response to a request would contain the requested resource e. If the file cannot be retrieved for some reason, an error status is returned see client error responses and server error responses. A dynamic site can return different data for a URL based on information provided by the user or stored preferences and can perform other operations as part of returning a response e.

Most of the code to support a dynamic website must run on the server. Creating this code is known as " server-side programming " or sometimes " back-end scripting ". The diagram below shows a simple architecture for a dynamic website. Let's now turn our attention to the code involved in server-side and client-side programming.

In each case, the code is significantly different:. Code running in the browser is known as client-side code and is primarily concerned with improving the appearance and behavior of a rendered web page.

This includes selecting and styling UI components, creating layouts, navigation, form validation, etc. The server-side code handles tasks like validating submitted data and requests, using databases to store and retrieve data and sending the correct data to the client as required. The server-side code has full access to the server operating system and the developer can choose what programming language and specific version they wish to use. Again, while both client and server-side code use frameworks, the domains are very different, and hence so are the frameworks.

Note : Client-side frameworks are often used to help speed up development of client-side code, but you can also choose to write all the code by hand; in fact, writing your code by hand can be quicker and more efficient if you only need a small, simple web site UI.

In contrast, you would almost never consider writing the server-side component of a web app without a framework — implementing a vital feature like an HTTP server is really hard to do from scratch in say Python, but Python web frameworks like Django provide one out of the box, along with other very useful tools.

Companies like Amazon use server-side programming to construct search results for products, make targeted product suggestions based on client preferences and previous buying habits, simplify purchases, etc. Banks use server-side programming to store account information and allow only authorized users to view and make transactions. Other services like Facebook, Twitter, Instagram, and Wikipedia use server-side programming to highlight, share, and control access to interesting content.

Some of the common uses and benefits of server-side programming are listed below. You'll note that there is some overlap! Imagine how many products are available on Amazon, and imagine how many posts have been written on Facebook? PDFs, images, etc. The content can even be targeted for the type of client device that is receiving it.

Because the information is in a database, it can also more easily be shared and updated with other business systems for example, when products are sold either online or in a shop, the shop might update its database of inventory. Note : Your imagination doesn't have to work hard to see the benefit of server-side code for efficient storage and delivery of information:.

Using a database allows these to be stored and shared efficiently, and it allows the presentation of the information to be controlled in just one place. Servers can store and use information about clients to provide a convenient and tailored user experience. For example, many sites store credit cards so that details don't have to be entered again. Sites like Google Maps can use saved or current locations for providing routing information, and search or travel history to highlight local businesses in search results.

Note: Google Maps saves your search and visit history. Frequently visited or frequently searched locations are highlighted more than others. Server-side programming allows sites to restrict access to authorized users and serve only the information that a user is permitted to see. The site you are on right now controls access to content: articles are visible to everyone, but only users who have logged in can edit them.

To try this, click on the Edit button at the top of this page — if you are logged in you will be shown the edit view; if you are not logged in you will be taken to the sign-up page. Note : Consider other real examples where access to content is controlled. For example, what can you see if you go to the online site for your bank?

What information can you see that only the bank can change? Server-side programming allows developers to make use of sessions — basically, a mechanism that allows a server to store information on the current user of a site and send different responses based on that information.

This allows, for example, a site to know that a user has previously logged in and display links to their emails or order history, or perhaps save the state of a simple game so that the user can go to a site again and carry on where they left it.

Note : Visit a newspaper site that has a subscription model and open a bunch of tabs e. The Age. Eventually, you will start to be redirected to pages explaining how to subscribe, and you will be unable to access articles. This information is an example of session information stored in cookies. Note : The most common type of notification is a "confirmation of registration".

Pick almost any large site that you are interested in Google, Amazon, Instagram, etc. You will shortly receive an email confirming your registration, or requiring acknowledgment to activate your account. A website may collect a lot of data about users: what they search for, what they buy, what they recommend, how long they stay on each page.

Server-side programming can be used to refine responses based on analysis of this data. For example, Amazon and Google both advertise products based on previous searches and purchases. Note : If you're a Facebook user, go to your main feed and look at the stream of posts. Note how some of the posts are out of numerical order - in particular, posts with more "likes" are often higher on the list than more recent posts.

Also look at what kind of ads you are being shown — you might see ads for things you looked at on other sites. Facebook's algorithm for highlighting content and advertising can be a bit of a mystery, but it is clear that it does depend on your likes and viewing habits! Congratulations, you've reached the end of the first article about server-side programming.

Lastly, you should understand that server-side code can be written in a number of programming languages and that you should use a web framework to make the whole process easier. In a future article we'll help you choose the best web framework for your first site. Skip to main content Skip to search Introduction to the server side.

Overview: First steps Next. In each case, the code is significantly different: They have different purposes and concerns.

They generally don't use the same programming languages the exception being JavaScript, which can be used on the server- and client-side. They run inside different operating system environments. Search for a number of keywords and note how the page structure doesn't change, even though the results do. Open two or three different products. Note again how they have a common structure and layout, but the content for different products has been pulled from the database.

Google search results are optimized based on previous searches. Go to Google search. Search for "football". Now try typing "favourite" in the search box and observe the autocomplete search predictions. Amazon regularly sends product e-mails that suggest products similar to those already bought or viewed that you might be interested in.

What Programming Language Is Primarily Used on the Web?

Web design is the process of creating websites. It encompasses several different aspects, including webpage layout, content production, and graphic design. While the terms web design and web development are often used interchangeably, web design is technically a subset of the broader category of web development. Websites are created using a markup language called HTML. Web designers build webpages using HTML tags that define the content and metadata of each page.

This method of styling a page is incredibly useful because it allows a website developer to change all of the same HTML elements on a page without the need to change each one individually. It allows developers to save time and to test new design styles with ease. JavaScript resembles more traditional computer programming languages but allows Internet users to perform certain actions on a website and interact with the content. The scripting language uses function calls and supports object-oriented elements.

Here you will get the material for computer IT and Web programming related courses and tutorials. As these tutorials are included in many of the academic schedules, you will need to get detailed information on them. As it will not possible for you to browse the web for every small topic, you can go for downloading the PDF files for having easy access to the information. Also tutorials, corrected exercises and practical work will make it easy for you to have a clear understanding of every topic.

This is a course on programming applications for the internet. Notice: These notes contain some errors and ommissions that will be corrected sometime soon. For now, anyone using these notes should consult the corrigendum provided by Neil Fraser. There is no textbook for this course. One could easily spend a thousand dollars on a collection of textbooks that contain the material covered in this course. Instead, since this is a course about Internet technologies, the course material will be available on the Internet. My office hours are Tuesdays from in room HP.
