Browser/Server System Services

"B/S System" refers to a system based on the architecture of browsers and servers. Users access the system through a web browser (websites are essentially the simplest form of a B/S system), while the core business logic is executed on the server side.

One of the advantages of B/S systems is that users can access the system through different devices and browsers.

Desktop application Services

Desktop applications are a type of software that runs in the desktop environment of personal computers, typically on desktop operating systems such as Microsoft Windows or MacOS. Most desktop applications provide a graphical user interface, allowing interaction with users through graphical elements like buttons, windows, and menus.

By the way, I am an MVP (Most Valuable Professional) in the Microsoft Visual Studio and Visual C# direction. :)

Mobile application Services

Mobile applications (Apps) are software designed and developed specifically for mobile devices, such as smartphones and tablets. These applications can be downloaded and installed through the device's app stores, such as the Apple App Store and Google Play Store.

Mobile apps cover a wide range of functionalities and purposes, including social media, games, productivity tools, news, entertainment, and more. Users can interact with mobile apps intuitively through touchscreens, making them very convenient and user-friendly in the mobile environment.
