A command that does not have a key combination assigned to it.
A communication between a single sender and a single receiver on a network.
A 16-bit character set capable of encoding almost all known characters and used as a worldwide character-encoding standard. Windows CE uses Unicode exclusively at the system level.
Uniform Resource Identifier (URI)
A number or name that uniquely identifies an element or attribute. URIs includes both Uniform Resource Names (URNs) and Uniform Resource Locators (URLs). URIs are a more-general scheme for locating resources on the Internet that focuses more on the resource and less on the location. In theory, a URI could find the closest copy of a mirrored document or locate a document moved from one site to another.When discussing XML today, URIs are URLs in nearly all cases, although it is expected that URNs will become more common in the future.
Uniform Resource Locator (URL)
The address of a resource on the Internet. URL syntax is in the form protocol://host/localinfo, where protocol specifies the means of returning the object, such as Hypertext Transfer Protocol (HTTP) or File Transfer Protocol (FTP). Host specifies the remote location where the object resides, and localinfo is a string-often a file name-passed to the protocol handler at the remote location. Also called Uniform Resource Identifier (URI).
1. The universal modem driver, provided with Windows CE .NET, that translates Telephony Service Provider Interface (TSPI) calls into AT commands and sends the commands to a virtual device driver that talks to the modem.
2. A universal modem that supports standard modem AT commands. In Windows CE .NET, universal modems are PC Cards.
Universal Computer Protocol (UCP)
UCP is a communication protocol for SMS-messages, that are sent via modem- or ISDN-access or so-called large customer accounts.
Universal Mobile Telephone System (UMTS)
UMTS is the name for the third generation mobile telephone standard in Europe, standardized by ETSI (see ETSI). UMTS will deliver broadband information at speeds up to 2 MBIT/s. Besides voice and data, UMTS will deliver audio and video to wireless devices anywhere in the world through fixed, wireless and satellite systems.
Universal Naming Convention (UNC)
The system of naming files among computers on a network so that a file on a given computer will have the same path when it is accessed from any of the other computers on the network. For example, if the directory c:\path1\path2\...pathn on a computer server is shared under the name pathdirs, a user on another computer would open \\servern\pathdirs\filename.ext to access the file c:\path1\path2\...pathn\filename.ext on the server.
Universal Serial Bus (USB)
A serial bus with a bandwidth of 1.5 megabits per second (Mbps) for connecting peripherals to a microcomputer. USB can connect up to 127 peripherals, such as external CD-ROM drives, printers, modems, mouse devices, and keyboards, to the system through a single, general-purpose port. This is accomplished by daisy-chaining peripherals together. USB supports hot plugging and multiple data streams. Developed by Intel, USB competes with DEC's ACCESS.bus for lower-speed applications.
Universally Unique Identifier (UUID)
A 128-bit value that uniquely identifies objects such as OLE servers, interfaces, manager entry-point vectors, and client objects. Universally unique identifiers are used in cross-process communication, such as remote procedure calling (RPC) and OLE. Also called globally unique identifier (GUID).
UNIX is a computer operating system that is designed to be used by many people at the same time and that has TCP/IP built-in. It is a quite common operating system for servers on the Internet.
A control containing a pair of arrow buttons that a user can click to increment or decrement a value, such as a scroll position. When used with an edit control or other type of companion control, an up-down control is referred to as a spin button.
A device driver for USB-compatible devices.
The collection of graphics, bitmaps, speech interactions, and/or other graphical and speech elements that allow a user to interact with a system like Windows CE for Automotive.
user level driver
A user-level DLL that controls devices connected to a Windows CE-based platform. A stream interface device driver presents the services of a hardware device to applications by exposing Win32 stream interface functions. Stream interface drivers also can control devices built into a Windows CE-based platform, depending on the software architecture for the drivers. Also called installable device driver.
A warning to the user that a timer event has occurred. The notification may require the user to perform some action to handle the notification or may generate a sound to alert a user. For example, the system may display a dialog box and play a sound or display an icon before a scheduled appointment. The user would tap the dialog box OK button to acknowledge the appointment. User notifications are always associated with an application.
user-initiated speech interaction
A voice command issued by the user to an application. The Command and Control system recognizes and handles the command.
An operating system image update mechanism, provided by the dial-up boot loader, that is designed to be used by users and field technicians. The operating system image is downloaded using a modem connection.
