(1) (Target Disk Mode) A method for transferring files between two Macs. See Target Disk Mode.

(2) (Target Display Mode) An iMac feature that enables the screen to function as an external monitor for another computer. See Target Display Mode.

(3) (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. In the simplest example, three incoming 1,000 bps signals (A, B and C) can be interleaved into one outgoing 3,000 bps signal as ABCABCABCABC. The receiving end divides the single stream back into its original signals.

TDM enabled the telephone companies to migrate from analog to digital on all their long distance trunks, and later to the local loops. TDM is widely used to combine multiple 64 Kbps streams into the 1.544 Mbps capacity of a T1 channel. For example, a channel bank converts 24 analog voice conversations into digital and then multiplexes them via TDM onto the T1. Contrast with FDM. See TDMA, circuit switching, channel bank and DS.


From FDM to TDM to Packet Switching
TDM has replaced FDM (frequency division multiplexing) for telco backbone networks, but packet switching is expected to become the norm for voice and data in the 21st century.

CONCLUSION: The present study concludes that there is a substantial gap of knowledge of Therapeutic drug monitoring (TDM) in second M.B.B.S students and M.B.B.S final year, so there is a need of incorporation of Therapeutic drug monitoring(TDM) in practical of second M.B.B.S curriculum and there is need to increase the weightage given to TDM in theory.

Consequently, the desired group velocity in the waveguide with the same normalized frequency 0.4228 (center wavelength 1550 nm) can be selected to generate TDM pulse repetition function by using slow light phenomenon.
In a completely flexible hybrid network, simultaneous routing of a wavelength to any TDM PON or second remote node is done, thus providing the possibility of getting access to every TDM PON by any wavelength, which offered capacity on demand and reduced traffic congestion at the same time.
Junius Kim [10] explained the emulated services, such as CES, allows TDM circuits to be bridged between locations by providing a pseudo wire tunnel across a provider's IP packet switched network.
Knowledge of the HISM, preferred role in TDM, personal factors that influence TDM, and preferred types of information sources accessed could be valuable data used to guide patient-physician communication and patient educational sessions.
Following TDM, patients were further monitored for slow response as defined by state guidelines [11]and if later identified, then referral was made to a state TB consultant (Figure 1).
