What is the Difference Between Client Server Application and Web Application?

🆚 Go to Comparative Table 🆚

The main differences between client-server applications and web applications are as follows:

Client-Server Applications:

  1. Installed on both client and server software to access the application.
  2. Use a two-tier architecture.
  3. Can be platform-specific or cross-platform, depending on the development approach.
  4. Require installation on the client's computer.
  5. Client-server applications can handle many client programs accessing a common database over a network.

Web Applications:

  1. Accessed through a browser.
  2. Executed on different web browsers.
  3. Use a multi-tier architecture, consisting of user client, middle tier, and application server.
  4. Platform-independent, as they require only a web browser.
  5. Do not require installation, as they run on browsers directly.

In summary, client-server applications are installed on both client and server machines, while web applications are accessed through a browser and executed on various web browsers. Client-server applications use a two-tier architecture, whereas web applications use a multi-tier architecture. Client-server applications can be platform-specific or cross-platform, while web applications are platform-independent. Client-server applications require installation, whereas web applications do not.

Comparative Table: Client Server Application vs Web Application

Here is a table comparing the differences between client-server applications and web applications:

Feature Client-Server Applications Web Applications
Architecture Multi-tier architecture (client, server, and sometimes a middle tier) Single-tier architecture (client)
Deployment Installed on the client's computer Entirely run on a web browser
Accessibility Requires continuous data exchange between the client and server Requires only a web browser for access
System Resources Limited access to system resources (e.g., memory, CPU, file system) Independent of system resources
Connection Connection is established using message passing over the network using protocols No direct connection to the server required
Examples FTP, email, web browsers, gateway, and file sharing applications Online email clients, social media platforms, and web-based office suites

In summary, client-server applications involve multiple tiers, with data exchanged between the client and server. They are installed on the client's computer and have limited access to system resources. On the other hand, web applications run entirely within a web browser and have independent access to system resources. They are accessed using a single-tier architecture and are examples of such include online email clients, social media platforms, and web-based office suites.
