A daemon is a term that originates from Unix and refers to a task that is running in the background. The Wind River multicasting daemon is the task that implements the multicast routing duties as required by a multicast proxy specification.
Smallest piece of data a DA server can send to a DA client. The OPC Foundation's Data Access Specification defines transfer of DA items between servers.
data link layer
The data link layer is layer two of the seven-layer Open Systems Interconnection (OSI) model. It transfers data between adjacent network nodes in a wide area network or between nodes on the same local area network segment. The data link layer prepares the packets for transmission, and detects and handles errors, such as packet collision. Examples of data link protocols are Ethernet for local area networks and PPP (Point-to-Point Protocol) for point-to-point connections.
The data plane is the code that makes up the forwarding step, for example, in the context of multicasting.

A datagram is a self-contained packet used in packet switching. A datagram contains enough information in the header to allow the network to forward it to the destination independently of previous or future datagrams. Thus, no setup is needed before a computer tries to send datagrams to a computer with which it has not previously communicated, unlike with virtual circuit protocols.
Driver Certification Kit
Distributed COM. DCOM connects COM clients and servers across a network, and instantiates and binds objects across the network. Currently available only on Windows 2000 and NT 4.0. You must install DCOM separately for Windows 95.
