Node (networking)

DEVICE OR POINT WITHIN A NETWORK CAPABLE OF CREATING, RECEIVING, OR TRANSMITTING DATA

Node (IT); Network node; Node (telecommunications); Virtual node; Virtual nodes; Network nodes; Intermediate node

In telecommunications networks, a node (, ‘knot’) is either a redistribution point or a communication endpoint. The definition of a node depends on the network and protocol layer referred to.

network node

DEVICE OR POINT WITHIN A NETWORK CAPABLE OF CREATING, RECEIVING, OR TRANSMITTING DATA

Node (IT); Network node; Node (telecommunications); Virtual node; Virtual nodes; Network nodes; Intermediate node

<networking> (node) An addressable device attached to a computer network. If the node is a computer it is more often called a "host". (2004-08-25)

Sinoatrial node

GROUP OF CELLS LOCATED IN THE WALL OF THE RIGHT ATRIUM OF THE HEART

SA node; Sinoatrial Node; Sinus node; Sinus Node; Sinoatrial cell; Sinoatrial; Sa node; Atrial sinus; Sino-atrial node; Sinoastrial node; Sino atrial node; Sinuatrial mode; Sinu-atrial node; The sinoatrial node; SA Node; Nodus sinuatrialis; Sinuatrial node; Sinoatrial nodes; Sinoatrial (SA) node; Sinuauricular node; S-A node; SA nodal; S-A nodal

The sinoatrial node (also known as the sinuatrial node, SA node or sinus node) is an oval shaped region of special cardiac muscle in the upper back wall of the right atrium made up of cells known as pacemaker cells. The sinus node is approximately fifteen mm long, three mm wide, and one mm thick, located directly below and to the side of the superior vena cava.

Tree (data structure)

In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, except for the root node, which has no parent. These constraints mean there are no cycles or "loops" (no node can be its own ancestor), and also that each child can be treated like the root node of its own subtree, making recursion a useful technique for tree traversal. In contrast to linear data structures, many trees cannot be represented by relationships between neighboring nodes in a single straight line.

Binary trees are a commonly used type, which constrain the number of children for each parent to at most two. When the order of the children is specified, this data structure corresponds to an ordered tree in graph theory. A value or pointer to other data may be associated with every node in the tree, or sometimes only with the leaf nodes, which have no children.

The abstract data type can be represented in a number of ways, including a list of parents with pointers to children, a list of children with pointers to parents, or a list of nodes and a separate list of parent-child relations (a specific type of adjacency list). Representations might also be more complicated, for example using indexes or ancestor lists for performance.

Trees as used in computing are similar to but can be different from mathematical constructs of trees in graph theory, trees in set theory, and trees in descriptive set theory.
