USB Glossary Virtual Port WAN WBT WinFrame WINS Winterm WTS X-ON/X-OFF 313 Universal Serial Bus. An external peripheral interface standard for communication between computer and external peripherals over an inexpensive cable using biserial transmission. USB works at 12 Mbps with specific consideration for low-cost peripherals. USB cables can be up to 5 meters long. Incoming Telnet and rlogin connections are not associated with a physical port. Instead, they are associated with a virtual port, port 0, which serves for the duration of the connection. Each virtual port is created with a default set of characteristics. The Define Port commands can be used to customize a virtual port during the Telnet/Rlogin session; however, these customizations can not be saved. The port reverts to the default set of characteristics when the session is closed. Wide Area Network. A data-communications system covering a large geographic area, usually digital circuits having moderate to high data rates (e.g., 56 to 64 kbps up to 1.5 to 2 Mbps). Windows-based Terminal. A thin-client device that connects to a Citrix WinFrame or MetaFrame server to provide application access. The key differentiation of a WBT from other type devices is that all the application execution occurs on the server. There is no downloading or local processing of applications at the client. A multi-user Windows application server, based on Windows NT, developed under license from Microsoft. This application was developed by Citrix Systems, Inc. Windows Internet Naming Service. WINS allows machines to dynamically register their name-to-address mappings. WINS is also a flat name space without the concept of hierarchy and requires each WINS server to maintain a complete database of entries through replication.
