  2. Technical data management system - Wikipedia

    en.wikipedia.org/wiki/Technical_data_management...

    A technical data management system (TDMS) is a document management system (DMS) pertaining to the management of technical and engineering drawings and documents. Often the data are contained in 'records' of various forms, such as on paper, microfilms or digital media. Hence technical data management is also concerned with record management ...

  3. Time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiple_access

    Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [1] The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same ...

  4. Time-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiplexing

    Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.

  5. Statistical time-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Statistical_time-division...

    Statistical multiplexing allows the bandwidth to be divided arbitrarily among a variable number of channels (while the number of channels and the channel data rate are fixed in TDM). Statistical multiplexing ensures that slots will not be wasted (whereas TDM can waste slots). The transmission capacity of the link will be shared by only those ...

  6. TDM over IP - Wikipedia

    en.wikipedia.org/wiki/TDM_over_IP

    TDM over IP. In computer networking and telecommunications, TDM over IP (TDMoIP) is the emulation of time-division multiplexing (TDM) over a packet-switched network (PSN). TDM refers to a T1, E1, T3 or E3 signal, while the PSN is based either on IP or MPLS or on raw Ethernet. A related technology is circuit emulation, which enables transport of ...

  7. Transportation demand management - Wikipedia

    en.wikipedia.org/wiki/Transportation_demand...

    Transportation demand management or travel demand management (TDM) is the application of strategies and policies to increase the efficiency of transportation systems, that reduce travel demand, or to redistribute this demand in space or in time. [1][2] In transport, as in any network, managing demand can be a cost-effective alternative to ...

  8. Multiplexing - Wikipedia

    en.wikipedia.org/wiki/Multiplexing

    Time-division multiplexing (TDM) Time-division multiplexing (TDM) is a digital (or in rare cases, analog) technology that uses time, instead of space or frequency, to separate the different data streams. TDM involves sequencing groups of a few bits or bytes from each individual input stream, one after the other, and in such a way that they can ...

  9. Frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Frequency-division...

    t. e. In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a microwave radio link, cable or ...
