What Is a Web Application?

A web application, often known as a web app, is an accessible piece of software that runs remotely on a server and can be accessed via the internet using a web browser interface. It works as a flexible tool that can be tailored to different purposes and audiences, fostering convenient and secure connections.

These digital marvels enable seamless interactions between businesses and customers, ensuring an efficient exchange of information and services. By gathering, analyzing, and displaying crucial data, they enable businesses to interact with customers effectively, resulting in quick and safe transactions.

A web application's strength lies in its capacity to leverage the power of both server-side scripts (such as PHP and ASP) for data management and client-side scripts (such as JavaScript and HTML) for user interaction.

Developers building web applications

Websites frequently serve as the virtual home for web applications, which enable users to complete particular tasks while browsing. These tasks span a wide range, from running online shops with features like checkouts and payment processing to interacting with chat features or product customization tools–these are just a few of the must-have features of web apps.

In simple words, consider a web application as a digital tool or service you use on the internet. It's like a virtual version of something you might use in real life, but it works on your computer or phone through a web browser.

For example, when you check your email on a website like Gmail, that's a web application. It lets you send, receive, and organize your emails, just like you would with physical mail. But it's all done online.

Web applications can do all sorts of things, from shopping online and social media to online banking and watching videos. They're helpful online tools that make your life easier, and you can access them from anywhere with an internet connection!

What is a Web-Based Application?

Web-based applications specifically refer to software applications that are entirely dependent on the web and are accessed through a web browser. These applications don’t require any installation or download on the user's device.

They run entirely on remote servers, and users interact with them by accessing a website URL through their browser. The term "web-based applications" is often used to emphasize the online nature of the application, indicating that it relies entirely on internet connectivity for operation.

Though, what is the difference between web applications and web-based applications? While both terms are related to software accessed via web browsers, "web applications" is a broader category that encompasses various types of browser-based software, including advanced SPAs (e.g. Maps, Gmail) and PWAs (e.g. Pinterest, Uber), while "web-based applications" specifically refers to software that operates exclusively through web browsers and relies on remote servers for its functionality (e.g. Google Workspace, Microsoft Office).

History of Web Applications

Everything started in 1989 when Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW). The fundamental concept behind the World Wide Web (WWW) was to integrate the advancing technologies of computers, data networks, and hypertext to create a robust and user-friendly global information system.

The 1990s marked the introduction of web browsers. The release of the Mosaic web browser in 1993 played a pivotal role in popularizing the web. It allowed the display of images and text on web pages, making the web more visually appealing.

However, discovering the roots of a contemporary web app takes us on a journey back to the early 1990s when the digital landscape was decorated with textual treasures in the form of static HTML pages.

As time progressed, the web expanded to accommodate images, videos, and audio, yet these elements remained confined within their stillness. The yearning for dynamic HTML pages prospered in 1990-1995 with the emergence of Java-Script in 1995—a client-side programming language that breathed life into web pages, infusing them with captivating interactive components, including the mesmerizing dance of vector animations.

The first modern API put to use was the Salesforce API, which was launched by this company during the IDG Demo conference on February 7, 2000.

Web 2.0 is a relatively new term, having only come into popular use about twenty years ago, in 1999. It was first coined by Darcy DiNucci and then became popularized by Tim O’Reilly and Dale Doughtery at a conference in 2004.

Web 2.0 represented a shift towards more interactive and collaborative web applications.

Services like Facebook, YouTube, and Wikipedia exemplified this trend.

The tides of transformation truly surged in 2005 with the advent of Ajax—an innovative approach that revolutionized web design and app development, paving the way for responsive, asynchronous web apps that seamlessly adjusted to users' needs.

The concept of web applications has become a significant milestone in the journey of the internet. Yet, as technology continued to evolve, there arose a need for more functionalities of web applications.

In the 2010s, the proliferation of smartphones and tablets led to a focus on responsive web design, ensuring web applications were accessible across various devices.

Ultimately, the efforts led to the birth of Progressive Web Applications (PWAs) in 2015, ingeniously pioneered by Alex Russell and Frances Berrman. Essentially, they bridge the gap between web apps and native apps, seamlessly blending functionality to a point where users discern no distinction between the two.

How a Web Application Works?

The best part about web applications is that there’s no need to download them on your PC or laptop. They work on a network and can be accessed with the help of a web browser whether you use Safari, Google Chrome, and so forth.

To be functional, a web application needs a web server, app server, and database. Web servers handle incoming client requests, while application servers execute requested tasks. And storing essential data is the role of a database.

Web applications are typically written in languages that browsers understand, like JavaScript and HTML. These languages depend on the browser to make the program work. Some apps are interactive and need the server to do some work, while others are fixed and don't need any help from the server.

This is how the usual process of a web application goes:

  1. The user sends a request to the web server using the internet, either through a web browser or the app's interface

  2. The web server passes this request to the proper web application server

  3. The web application server does the task asked for, like getting data from a database or working on the information - then, it creates the outcomes based on this data

  4. The web application server sends the results back to the web server, including the wanted info or processed data

  5. Finally, the web server replies to the user with the requested info, which shows up on their screen. (Indeed)
