Which of the following is true about custom applications?

Custom applications are specifically designed to meet the unique needs of a particular business or user. The statement that custom applications can run on single computers or combine data from multiple sources is accurate because they are highly adaptable. A business may design a custom application to operate on a single workstation for localized tasks or to aggregate and process data from various databases and systems, which is essential for larger operations or when integrating diverse data streams is necessary.

Unlike options that suggest they are always free to use or require extensive hardware upgrades, custom applications often involve costs for development and maintenance which vary depending on the complexity and functionality required. While some custom applications are hosted in the cloud, it is not universally true that all custom applications are cloud-based as they can also be implemented on local servers or desktops depending on the organization’s needs and infrastructure. Thus, the flexibility of custom applications in terms of operational environment is a key reason why the ability to run on single computers or aggregate data from multiple sources is true and highlights their versatility.
