A unidirectional network (also referred to as a unidirectional gateway or data diode) is a network appliance or device that allows data to travel in only one direction. Data diodes can be found most commonly in high security environments, such as defense, where they serve as connections between two or more networks of differing security ...
In information technology and computer science, the pattern of applying one-way mutations on an immutable data state is called unidirectional data flow. [1] Separation of state changes from presentation has many benefits and was popularized with Redux for unidirectional data flow combined with React for presenting, or rendering, data state.
Rings can be unidirectional, with all traffic travelling either clockwise or anticlockwise around the ring, or bidirectional (as in SONET/SDH). [1] Because a unidirectional ring topology provides only one pathway between any two nodes, unidirectional ring networks may be disrupted by the failure of a single link. [2]
Unidirectional may refer to: simplex communication, in communications theory; Half-duplex signaling behavior, using ITU standards; Uni-directional vehicle, a railcar ...
In the 1928 book The Nature of the Physical World, which helped to popularize the concept, Eddington stated: . Let us draw an arrow arbitrarily. If as we follow the arrow we find more and more of the random element in the state of the world, then the arrow is pointing towards the future; if the random element decreases the arrow points towards the past.
Unidirectional Link Detection (UDLD) is a data link layer protocol from Cisco Systems to monitor the physical configuration of cables and detect unidirectional links. UDLD complements the Spanning Tree Protocol which is used to eliminate switching loops .
Simplest unidirectional traveling-wave antenna. Consists of a straight wire one to several wavelengths long, suspended near the ground, connected to the receiver at one end and terminated at the other end by a resistor equal to its characteristic impedance (typically 400~800 Ω).
Unidirectional, which give a clear, single direction of flow; Bidirectional, which give a good linear direction, but it is unclear which direction along the linear trend the water flowed. Paleocurrents are usually measured with an azimuth, or as a rake on a bedding plane, and displayed with a Rose Diagram to show the dominant direction(s) of flow.
