Introduction to Desktop Software
To understand the concept of a desktop software it is first necessary to get acquainted with the concept of software. Software is defined as a computer program or a set of instruction for the computer to enable it to function accordingly, This software is required by computers to perform specific tasks, Software can be defined as a collective term for applications, programs, scripts that run on a computer or any other programmable device. The Softwares are classified into many categories based on different criteria. Softwares are classified into application software and system software based on the usability of the software or the intended users of the program.
Understanding Desktop Software
Desktop software or applications can be considered as a local version of a service or web applications that provide the interaction option between the application processing and user without having to directly connect with the web service. This desktop software have gained huge popularity as they provide cross-platform solutions to rather bulky web services along with the added advantage of not impacting the architecture in case of a failure.
Explain Desktop Software
Desktop applications are installed over the personal or work computer and these installations are necessary over each computer separately, The major con attached to a desktop application is that the update of such applications is very difficult and needs to be pushed on each computer where the application is installed separately. Desktop application is limited to presence over a physical location and thus face the usability constraint, The biggest advantage of a desktop application lies in the fact of its speed and performance which beats web application hands down as it is independent of internet connectivity, The desktop applications are standalone in nature and hence the constraint is not valid over the desktop software. Along with this web application have no constraint pertaining to bandwidth as again it is independent of any internet requirement.
How Desktop Software Work?
Desktop applications are binary executable files which run on the standalone desktop. Desktop apps generally have scope for multiple features simultaneously. A large set of simultaneous tasks or sequence of tasks performing responsibilities are imparted to the desktop application. In Windows OS desktop applications run with basic limited permissions which are by default necessary for the functioning of the app but these can be imparted with elevated administrative privileges by the user. For e.g. Some applications may not run correctly without such elevated permissions as these programs have the ability to alter the OS based files. Antivirus programs are examples of such programs.
Desktop applications can run multiple instances in parallel. Desktop Apps can run on any version of Windows. Some apps may not be compatible with older versions of Windows, this is decided by the basic programming features in the source code for the application. These desktop applications need to install additional configuration settings for the Windows-based services which grant them access to use various system resources and enable them to perform associated tasks based on customer requirement e.g. Antivirus and VPN applications.
Desktop applications may carry any contents associated with its functioning and are listed in the windows section of the Control Panel option of the PC and can also be uninstalled from this directory from a list option. Desktop applications provide an opportunity for manual updates by the user or executing the same automatically by using update services released in batches by the developer or updating apps or services. Desktop applications can be categorized on the basis of license type as proprietary and open-source.

1. System Software
They coordinate between the hardware and provide another software platform to work on, in a sense, it acts as a parent software enabling the environment and resources for them to be able to feed upon. It is the most primitive software in any computer operation and very vital for the proper functioning of the computer.
2. Application Software
Application software or in the plain language referred to as Apps are those which enable the user to perform the tasks of their choice. These are non-essential software and are installed by the user based on his /her requirements and in the environment provided by the system software.
3. Programming Software
Programming software is studio framework applications designed to write, test, troubleshoot and develop software programs and applications. There are many programming language editors like Eclipse for Java, Visual studio for dotnet come under this category. They are used for creating system and application software and provides a platform for running the programming based codes inheriting the programming features of the frameworks.
4. Freeware
This software are available for the users for downloading and installation free of cost and does not require any licensing.
5. Shareware Software
Shareware software is for free on a trial usage. They can be shared with everyone and prevents major functions however gives an insight into the working of the parent software and stop working or informs the user to purchase the full version on the expiration of the trial period.
6. Browsers
These are applications used to view and access the websites and their contents. They are applications designed to render upon the markup languages used in designing the web interface of any website.
Conclusion
To conclude let us summarize the pros of a desktop application:-
The biggest advantage of any desktop application is its high efficiency as it is a standalone installation designed to cater only one user at a time the resource dedication and event handling is done is maximized to suit user needs independent of the server side connection. The desktop application carries with it the high interface flexibility as they are designed keeping the platforms and interface in mind. Desktop applications are more user-friendly, responsive, customizable. Stability is also higher for native desktop applications when compared to their web partners. As any desktop application is an executable program, they are independent of any internet requirement and perform as designed by the developer to work upon.
