Serial portOn computers, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various peripherals, and directly between computers.
Bottled waterBottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in plastic or glass water bottles. Bottled water may be carbonated or not. Sizes range from small single serving bottles to large carboys for water coolers. Although vessels to bottle and transport water were part of the earliest human civilizations, bottling water began in the United Kingdom with the first water bottling at the Holy Well in 1622.
Data terminal equipmentData 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 or tail circuit. A DTE device communicates with the data circuit-terminating equipment (DCE), such as a modem. The DTE/DCE classification was introduced by IBM. A DTE is the functional unit of a data station (station, terminal) that serves as a data source or a data sink and provides for the data communication control function to be performed in accordance with the link protocol.
ElectrodeionizationElectrodeionization (EDI) is a water treatment technology that uses DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is usually a polishing treatment for reverse osmosis (RO). EDI differs from other RO polishing technologies, such as chemically regenerated mixed beds, in that it is continuous and requires no chemical regeneration. EDI is sometimes referred to as "continuous electrodeionization" (CEDI) since the electric current regenerates the ion exchange resin mass continuously.
