Serial port. A male D-subminiature connector used for an RS-232 serial port on an IBM PC compatible computer along with the serial port symbol. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [ 1] This is in contrast to a parallel port, which communicates multiple ...
RS-232. A DB-25 connector as described in the RS-232 standard. Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [ 1] is a standard originally introduced in 1960 [ 2] for serial communication transmission of data. It formally defines signals connecting ...
1,2-Dichloroethane. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) The chemical compound 1,2-dichloroethane, commonly known as ethylene dichloride ( EDC ), is a chlorinated hydrocarbon. It is a colourless liquid with a chloroform -like odour.
1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2. The two compounds are isomers, each being colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...
Crossover cable. A null modem cable. A crossover cable connects two devices of the same type, for example DTE -DTE or DCE -DCE, usually connected asymmetrically (DTE-DCE), by a modified cable called a crosslink. [ 1] Such a distinction between devices was introduced by IBM . The crossing of wires in a cable or in a connector adaptor allows ...
DCE and DTE network. Data terminal equipment ( DTE) is an end instrument that converts user information into signals or reconverts received signals. It is also called data processing terminal equipment [1] or tail circuit. [citation needed] A DTE device communicates with the data circuit-terminating equipment (DCE), such as a modem.
Website. www.dce.com.cn. The Dalian Commodity Exchange ( DCE) ( simplified Chinese: 大连商品交易所; traditional Chinese: 大連商品交易所; pinyin: Dàlián Shāngpǐn Jiāoyìsuǒ) is a Chinese futures exchange based in Dalian, Liaoning province, China. It is a non-profit, self-regulating and membership legal entity established on ...
A data circuit-terminating equipment[ 1] ( DCE) is a device that sits between the data terminal equipment (DTE) and a data transmission circuit. It is also called data communication (s) equipment[ 2][ 3][ 4] and data carrier equipment. [citation needed] Usually, the DTE device is the terminal (or computer ), and the DCE is a modem .
