TCO Comparison
The following table summarizes and compares the total cost of ownership (TCO) for traditional terminal emulation and Web-to-host. The costs shown are annual recurring costs for a single user. The traditional terminal emulation costs are shown for two configurations. With manual configuration, the application is installed and configured manually and, therefore, yields a higher TCO. With automated configuration, the application installation and configuration has been automated and is distributed from a central site, resulting in a lower TCO.
