ed unacceptable delays in accessing centralized files and applications because of inadequate LAN capacity. Improvements in LAN capacity have eliminated these delays. Another factor inhibiting implementation is the fear that if a remote user wants to work on centralized files, and she is somewhere without an available broadband connection, productivity gains in centralizing applications and any modifications to the files will be lost. Multiple Operating Systems on Desktop Computers-Testing and Flexibility Software developers and IT staff use desktop virtualization on computers with multiple operating systems to test new applications as they are developed or before they are provided to an organization's staff. They do this by trying out the new software with a variety of operating systems such as Linux, Windows, and Mac operating systems to determine if the application is compatible with each of these operating systems. They additionally can test newer and older versions of these operating systems with various applications before making them available to internal staff or customers. Desktop virtualization can be installed on individual computers. A person with a Mac computer may wish to www.TechnicalPDF.com run a program that works only on Windows operating systems. To run a Windows program that is not available for Mac computers, they install the Windows operating system on a computer capable of supporting dual operating systems, and activate it to run the Windows- compatible application. A personal computer or laptop with adequate memory and processing power is required to avoid slowing down the computer with the use of dual operating systems. In addition to testing operating systems, IT staff also test upgraded versions of web browsers for compatibility with Mac, Windows, and other computer operating systems.
