Term of the Moment
AMOLED
Definition: node
(1) A single entity among many of the same type.
(2) For nodes in AI, see AI node.
(3) For nodes in Bitcoin, see Bitcoin node and blockchain.
(4) For the JavaScript platform, see Node.js.
(5) For a server in a network, see server node.
(6) Node typically refers to a single unit among any combination of computers, servers, switches and routers in a network. Nodes can be servers in a datacenter and modules in a server. A node refers to any entity that communicates with cooperating objects. See host, hub, switch and router.
(7) In database management, a node is an item of data that can be accessed by two or more routes. See DBMS.
(8) In the Document Object Model (DOM), which exposes HTML and XML content to an application or script, every element, every attribute of that element, and each piece of textual content for every attribute is considered a node. See DOM.
(9) In computer graphics, a node is an endpoint of a graphical element. See graphics.
(10) In multiprocessing systems, a node can be a single processor or system. In MPP (massively parallel processing), a node is one processor. In SMP (symmetric multiprocessing), a node is one computer system with two or more processors and shared memory. See SMP and MPP.
