Abbreviated STP, a link management protocol that is part of the IEEE 802.1 standard for media access control bridges. Using the spanning tree algorithm, STP provides path redundancy while preventing undesirable loops in a network that are created by multiple active paths between stations. Loops occur when there are alternate routes between hosts. To establish path redundancy, STP creates a tree that spans all of the switches in an extended network, forcing redundant paths into a standby, or blocked, state. STP allows only one active path at a time between any two network devices (this prevents the loops) but establishes the redundant links as a backup if the initial link should fail. If STP costs change, or if one network segment in the STP becomes unreachable, the spanning tree algorithm reconfigures the spanning tree topology and reestablishes the link by activating the standby path. Without spanning tree in place, it is possible that both connections may be simultaneously live, which could result in an endless loop of traffic on the LAN.
- spatial compression
A compression algorithm applied to a single frame of video independently, where the video image is compressed much like a JPEG image would be compressed.
- Spatial Data
Also known as geospatial data or geographic information it is the data or information that identifies the geographic location of features and boundaries on Earth, such as natural or constructed features, oceans, and more. Spatial data is usually stored as coordinates and topology, and is data that can be mapped. Spatial data is often accessed, […]
- spatial modeling
Analytical procedures applied with GIS. It is the set of procedures that simulates real-world conditions within a GIS using the spatial relationships of geographic features.
In video and computer games spawn is the reforming or appearance of a player somewhere in the game level. In FPS games, when a character is fragged the game is not over, but rather the character spawns in one of several set locations in the map and continues playing. Usually when a character spawns after […]
An electro-acoustic transducer that converts electrical signals into sounds loud enough to be heard at a distance. Synonymous with loudspeaker.
