what is a web app

Web apps have become very popular in recent years. With the rise of mobile devices, more and more people are accessing the Internet through their smartphones and tablets. Web apps allow users to access content and services directly from their web browsers, without having to download and install a native application on their devices. But what exactly is a web app? In this article, you will find out everything you need to know about this type of application.

What is a web app

A web app, short for "web application", is an application that runs in a web browser. Unlike native applications, which are downloaded and installed on a device, web apps are accessed through a web browser and run on a remote server. Web apps are designed to run on different platforms and operating systems, which means that users can access them from any device that has a web browser. Examples of web apps include Google Docs, Facebook, Instagram, Twitter and Netflix.

How web apps work

Web apps work in a similar way to web pages. When a user accesses a web app, the web browser communicates with the remote server where the application is hosted. The server sends the files needed to run the application in the user's browser. The application runs in the browser and the data is stored on the remote server. Each time the user interacts with the application, a request is sent to the remote server to update the data or perform some specific action.

Features of a web app

The following are some of the main features of a web app:

  • Accessibilityweb apps are accessible from any device with a web browser, making them a popular choice for those who do not want to download and install applications on their devices.
  • MultiplatformWeb apps are designed to work on different platforms and operating systems, which means that users can access them from any device with a web browser.
  • Automatic updates: Web apps are automatically updated on the remote server, which means that users always have access to the latest version of the application.
  • Reduced access to hardwareWeb apps have limited access to the device hardware, which means that they may have limitations in terms of functionality and performance.
  • Web technologyWeb apps use standard web technologies such as HTML, CSS and JavaScript, which means that developers can create applications with existing web tools and skills.

Web apps are different from native applications in several ways:

  1. InstallationNative applications are downloaded and installed directly on the user's device, while web apps run on a remote server and are accessed through a web browser.

  3. Performance: Native applications tend to be faster and perform better than web apps.
