Eliminate Your Fears And Doubts About Web Application

The app can be as simple as a bulletin board or contact form on a website or as complex as a word processor or multiplayer mobile game app that you download to your phone and Web Application.

 What is a client?

“Client” is used in a client-server environment to refer to a program that a person uses to run an application. A client-server environment is an environment in which multiple computers exchange information, such as entering information into a database. The “client” is the application use to enter information, and the “server” is the application use to store information.

What are the Benefits of Web Applications

The web application relieves the developer from the responsibility of creating a client for a specific type of computer or a specific operating system, so anyone can use the application with Internet access.

Since the client runs in a web browser , the user can use an IBM compatible computer or Mac. They can even run Windows XP or Windows Vista. They can even use Internet Explorer, although some applications require a specific web browser.

Web applications usually use a combination of server-side script (ASP, PHP, etc.) and client-side script ( HTML , Javascript, etc.). The client script deals with the presentation of information, while the server script deals with all the complex things like storing and retrieving information.

How long Have web Applications been around

Web applications have been around since before the World Wide Web was massively popular. This was seven years before the internet really began to gain traction outside of academia and technology.

The first major Webdesign Agentur applications were relatively simple, but in the late ’90s there was a push towards more complex web applications. Millions of users today use web applications to file tax returns, perform banking, keep in touch with friends and family, and more.

How web application evolved

Most web applications are based on a client-server architecture , where the client enters information while the server stores and receives information. Internet mail is an example, and companies like Yandex, Google and Microsoft offer web mail clients.

Over the past several years, web applications have been actively develope for functions that usually do not require a server to store information. For example, your word processor stores documents on your computer and doesn’t need a server.

Web applications can provide the same functionality and benefit from running on multiple platforms. For example, a web application can act as a word processor, storing information in the cloud and allowing you to “download” a document to your personal hard drive.

If you’ve been using the Internet long enough to see how popular web applications such as email clients have change over the years, you’ve seen how sophisticate web applications are becoming. Much of this complexity comes from AJAX, which is a programming model for building more responsive web applications.

G Suite (formerly Google Apps), Microsoft Office 365 are other examples of the latest generation of web applications. Mobile apps that connect to the internet (such as the Facebook app, Dropbox app, or online banking app) are also examples of how web apps have been redesigne to accommodate the increasingly popular use of the mobile internet.

1. How web applications differ from websites

For me, a site is primarily something informational and static: a company’s business card, a recipe site, a city portal or a wiki. 

Sites contain various statics, which, like an HTML file, are not generate on the fly. Most often these are pictures, CSS files, JS scripts, but there can be any other files: mp3, mov, csv, pdf.

Blogs, business cards with a contact form, landing pages with a bunch of effects, I also refer to sites for simplicity. Although, unlike completely static sites, they already include some kind of business logic.

And a web application is something technically more complex. Here HTML pages are generate on the fly depending on the user’s request. Email clients, social networks, search engines, online stores, online business programs, these are all web applications.

2. What are web applications

Web applications can be divide into several types, depending on the different combinations of its main components:

Backend (backend or server part of the application) runs on a remote computer, which can be located anywhere. It can be written in different programming languages: PHP, Python, Ruby, C # and others. If you create an application using only the server side, then as a result of any transitions between sections, submitting forms, updating data, the server will generate a new HTML file and the page in the browser will reload.

Frontend (frontend or client part of the application) runs in the user’s browser. This part is written in the Javascript programming language. The application can only consist of the client part if it is not require to store user data for longer than one session. These can be, for example, photo editors or simple toys.

Single page application (SPA or single page application).

 A more interesting option when both backend and frontend are used. Using their interaction, you can create an application that will work without page reloading in the browser at all. Or in a simplified version, when transitions between sections cause reloads, but any actions in the section are dispense with.

In development, a framework is a set of ready-made libraries and tools that help you create web applications. As an example, I will describe the principle of operation of the Django framework written in the Python programming language.
