What is Web App or Web-Apps?

A Web App (short for Web Application) is a software application that runs on a web server and is accessed through a web browser over the internet. Unlike traditional desktop applications, which need to be installed on a local computer, web apps are accessible from any device with a web browser, providing greater flexibility and ease of access.

Key Characteristics of Web Apps:

1. Accessibility: Web apps can be accessed from any device with an internet connection and a web browser, making them platform-independent. This means they can be used on desktops, laptops, tablets, and smartphones without needing to download or install the software.
2. Cross-Platform Compatibility: Since web apps run in a browser, they are generally compatible with multiple operating systems, such as Windows, macOS, Linux, Android, and iOS.
3. Ease of Maintenance: Updates and maintenance are handled on the server-side, meaning users automatically access the latest version of the web app without needing to install updates.
4. Interactivity: Modern web apps often provide interactive features similar to desktop applications, utilizing technologies like JavaScript, HTML5, CSS3, and AJAX to enhance user experience.
5. Server-Client Architecture: Web apps typically follow a client-server architecture, where the client (web browser) interacts with the server to retrieve and display information. The server handles data processing, storage, and business logic.

Examples of Web Apps:

• Email Clients: Gmail, Outlook.com
• Productivity Tools: Google Docs, Microsoft 365, Trello
• Social Media Platforms: Facebook, Twitter, Instagram
• E-commerce Platforms: Amazon, eBay
• Streaming Services: Netflix, Spotify
