For instance, in a vibrating guitar string, the ends of the string are nodes. By changing the position of the end node through frets , the guitarist changes the effective length of the vibrating string and thereby the note played. The opposite of a node is an anti node , a point where the amplitude of the standing wave is a maximum. These occur midway between the nodes.

Orphan date February 2009 In telecommunication s, node to node data transfer is the movement of data from one node networking node of a Telecommunications network network to the next. In the OSI model it is handled by the lowest two layers, the data link layer and the physical layer . In most communication systems, the transmitting point applies source coding , followed by channel coding , and lastly, line coding . This produces the baseband signal. Some systems then use modulation to multiplex many baseband signals into a broadband signal. The receiver un does these transformations in reverse order demodulation, trellis decoding, error detection and correction, decompression . Some communication systems omit one or more of these steps, or use techniques that combine several of these steps together. For example, a Morse code transmitter combines source coding, channel coding, and line coding into one step, typically followed by an amplitude modulation step. Barcode s, on the other hand, add a checksum digit during channel coding, then translate each digit into a barcode symbol during line coding, omitting modulation. Source coding See main article Data compression Source coding is the elimination of redundancy to make efficient use of storage space and or transmission channels. Examples of source coding are Huffman coding Morse code Binary coding Channel coding See main article Error correction and detection . In digital telecommunication s, channel coding is a pre transmission mapping applied to a digital signal or data file, usually designed to make error correction or at least Error detecting code error detection possible. Error correction is implemented by using more numerical digit digit s bit s in case of a binary channel than the number strictly necessary for the samples, and having the receiver compute the most likely valid message that could have resulted in the received one. Types of channel coding include Parity check s Hamming code Reed Muller code Reed Solomon ... more details

Examples include a USB hard disk , a telephone , and an airliner . Mesh nodes communicate with each other and use some sort of ad hoc networking protocol to route messages amongst themselves without the need for a traditional, hierarchical routing model. This also allows for nodes to join, move among, and drop out of the network without having to make administrative changes.

Image BTS NodeB antenna Sopot.jpg right thumb 300px BTS & Node B antenna mounted on the church tower, Sopot, Poland Node B is a term used in UMTS equivalent to the BTS base transceiver station description used in GSM. It is the hardware that is connected to the mobile phone network that communicates directly with mobile handsets. In contrast with GSM base stations, Node B uses WCDMA TD SCDMA as the air interface technology. As in all cellular systems, such as UMTS and GSM , the Node B contains radio frequency transmitter s and the receiver s used to communicate directly with mobile devices, which move freely around it. In this type of cellular network, the mobile devices cannot communicate directly with each other but have to communicate with the Node B. Traditionally, the Node Bs have minimum functionality, and are controlled by an RNC Radio Network Controller . However, this is changing with the emergence of High Speed Downlink Packet Access HSDPA , where some logic e.g. retransmission is handled on the Node B for lower response times. Differences between a Node B and a GSM base station Frequency use The utilization of WCDMA technology allows cells belonging to the same or different Node Bs and even controlled by different Radio Network Controller RNC to overlap and still use the same frequency in fact, the whole network can be implemented with just one WCDMA Technology frequency pair .

Refimprove date January 2007 In electrical engineering , node refers to any point on a circuit where two or more circuit elements meet. For two nodes to be different, their voltages must be different. Without any further knowledge, it is easy to establish how to find a node by using Ohm s Law V IR. When looking at circuit schematics, ideal wires have a resistance of zero. Since it can be assumed that there is no change in the potential across any part of the wire, all of the wire in between any components in a circuit is considered part of the same node. ref Smith, Ralph J. 1966 , Circuits, Devices and Systems , Chapter 2, John Wiley & Sons, Library of Congress Catalog Card No. 66 17612 ref Voltage Current Resistance br since voltage is a measure of potential difference the voltage between any two parts of the same node is br br V sub ab sub Current 0 So at any two points on the same node, the change in potential difference is 0. Therefore, throughout the entire node the voltage is the same. Image Nodes2.svg frame right Each different color in circuit above is a different node In this circuit diagram the voltage in the green node is the same throughout, likewise, the voltages in the blue node and the red node are the same throughout. In most cases, the voltage difference between one point on a piece of metal such as a copper wire , and the voltage at another point of the same piece of metal or on other bits of metal with metal to metal contact with the first piece of metal, is so small that it is usually considered insignificant. So every bit of that connected metal can be considered part of the same node. Some notable exceptions, where the voltage difference is large enough to become significant, include high precision resistance measurements using four terminal sensing Kelvin connection the difference in voltage between ground and neutral , between the neutral wire and the safety ground in a domestic AC power plugs and sockets , can be fatal.

In Resource Description Framework RDF , a blank node also called bnode is a node in an RDF graph representing a resource for which a URI or literal is not given. The resource represented by a blank node is also called an anonymous resource . By RDF standard a blank node can only be used as subject or object in an RDF triple, although in some syntaxes like Notation 3 ref Berners Lee, T. http www.w3.org DesignIssues Notation3.html Notation3 N3 A Readable RDF syntax , World Wide Web Consortium ref it is acceptable to use a blank node as a predicate. If a blank node has a node ID not all blank nodes are labeled in all RDF serializations , it is limited in scope to a serialization of a particular RDF graph, i.e. the node p1 in the subsequent example does not represent the same node as a node named p1 in any other graph. Example John has a friend born the 21st of April can be written with two triples linked by a blank node representing the anonymous friend of John. ex John foaf knows p1 p1 foaf birthDate 04 21 The first triple reads John knows p1 . The second triple reads p1 is born on April 21st ex John is a named resource, which means this resource is absolutely identified by the URI obtained by replacing the ex prefix by the XML namespace it stands for, such as nowiki http example.org Person John nowiki . p1 represents John s anonymous friend, not identified by a URI. One can know by the semantics declared in the FOAF software FOAF vocabulary that the class of p1 is foaf Person.
