An application that can only be executed in a local system with a local call is called a desktop application or Desktop apps. In simple words, a program that can be accessed only on one computer in which it is installed by a single user is called a desktop application. Desktop applications need installation and they are compatible with the single operating system only. It can not be accessible from the remote user via a network.
The applications installed on the system’s local server known as the desktop apps, you can install it from the online websites or use the CD drive to complete the installation process. After the installation process, it does not require any internet connection to access, it works on the system’s local server.
Desktop apps are restricted by the hardware requirements of the device on which they run. It contrasts with “Web-based application or Web application” which requires the Web browser to run. Desktop programs are mounted on a desktop computer for personal use or work.
Desktop Application Examples
The list of desktop applications are:-
- Windows File Explorer (used to find files on our computer)
- Microsoft Office applications (Word, Excel, and, etc.)
- LibreOffice Applications
- Web Browser Softwares (Chrome, Firefox, Internet Explorer, and e.t.c.)
- Adobe Photoshop
- Video Editing Softwares (Openshot, Shotcut, Kdenlive, and e.t.c.)
- TweetDeck (lets you use Twitter on the computer outside of a web browser)
- Multimedia Applications (VLC player)
To use the google chrome, installation is necessary. Without installing chrome we can’t use it and access it. It is platform dependent i.e. Chrome for windows is different from Chrome in Android because in Windows it has .exe and in Android, it has another extension. At a time only one user can access the chrome on the computer.
Types based on interface
Based on the interface the desktop applications can be categorized in two types:
- CUI (Character user interface) based desktop applications
- GUI (Graphical user interface) based desktop applications
CUI Based Desktop Applications
CUI stands for the character user interface. An application that reads input from the end-user by providing text-based character messages is called the CUI application.
CUI application doesn’t have any special windows, it executes directly in the cmd window or terminal. It doesn’t have different fonts, colors, graphics images and It can read one value at a time to application. It can’t provide complete information to the end-user. After entering input, we can’t change it. Because value is already submitted to the application. After the output displayed the program execution is terminated, we must run this program again for other inputs. In Java, it can be developed by using CMD line args application and the buffered reader or using a Scanner or by using console.
GUI Based Desktop Applications
GUI stands for the graphical user interface. An application that reads input values from the end-user by providing a separate window with the required number of labels, text boxes, buttons is called GUI application. By default, every internet application is also an example of GUI application because in internet application from the client system to server system we must pass all input values at a time.
GUI provides different fonts, colors, graphics, and images. It can read and pass all input values at a time to application. It can provide complete information and more clarity to the end-user. We can change the value because the value is not submitted to the application. After the output display program is not terminated, we can use some currently running program for new inputs.
