The examples include Microsoft Word, media players (like vlc), and games that do not require internet connectivity.
What is standalone and client-server application?
Key takeaways:
Standalone applications operate independently on a single device, while client-server applications rely on network connections and consist of distinct client and server components.
Standalone applications store data locally, whereas client-server applications centralize data on a server.
Standalone applications typically serve single users, while client-server applications support multiple users accessing shared resources.
Standalone applications are easier to maintain individually, while client-server applications offer centralized maintenance but can be more complex.
Standalone applications are suitable for offline tasks such as desktop applications, while client-server applications are better suited for collaborative environments like web applications and enterprise systems.
Understanding the differences between standalone and client-server applications is crucial for designing effective systems. Both architectures serve distinct purposes and are suited for different types of tasks and environments.
In this Answer, we will explore the characteristics, key differences, and use cases for each type of application.
Standalone application
A standalone application is a program that can operate independently without a network connection or offline. We must thus include all the resources the program will need when preparing such an application. These resources can be files containing program configuration, pictures such as the application’s icon, etc.
The majority of our programs when learning to write applications will probably fall into this group. Since we won’t need to communicate with other programs, creating these applications is typically simple. Text editors, such as Notepad on Windows or TextEdit on Mac, and straightforward games are a few examples of software that fits under this category.
Characteristics of standalone applications
Bundles all required files, operating independently without external dependencies.
Stores data on the user's device, such as in a file system or local database.
Often features a graphical user interface (GUI) for easy interaction.
Leverages the device's full processing power for faster performance.
Client-server application
Client-server is a model we can use to create distributed applications, which are applications that run on more than one machine.
The idea behind the client-server model is that we have at least two computers involved. One acts as the server and all the others have the role of the client. Clients and server need to communicate with each other. It is always the client who initiates the communication.
The server can communicate with one or several clients at a time, depending on the use case.
A server connected to several clients
This means we can use different computers to handle different parts of an application’s responsibility. We can let one computer deal with one aspect of a problem and another computer work on a different aspect of the same problem.
These two computers then need to communicate their results, usually to a single computer, which can then assemble the different results into one solution.
Characteristics of client-server applications
Client and server components are distinct, allowing for specialized functions and responsibilities.
Requires network connections for communication, making it reliant on availability.
Data is managed on the server, facilitating centralized access.
Easily scales by adding clients or server resources to accommodate increased loads.
Standalone vs. client-server application
Below are some common differences between standalone and client-server applications:
Standalone Application | Client Server Application |
Installed on a single device | Installed on multiple devices with a central server |
Does not require network connectivity or external resources | Relies on network connectivity and a central server |
Operates independently on the device | Involves interaction with a central server for processing |
Manages data locally on the device | Centralized data management on the server |
Easy to maintain and update individually | Centralized maintenance but can be complex |
Single user can use a standalone application | Multiple users can use client-server application |
Use case: desktop applications | Use case: web apps, enterprise systems, mobile apps |
Conclusion
A standalone application runs independently on a single device without needing external resources or network connectivity. In contrast, a client-server application operates in a networked environment where client devices send requests to a central server for processing. Understanding the difference between these two models helps determine the appropriate approach based on user needs, available resources, and desired functionality.
