1, The full form of MTBF is Mean Time Between Failure(s). It’s used on Computing ,Hardware in Worldwide

Mean time between failures is the predicted elapsed time between inherent failures of a mechanical or electronic system, during normal system operation. MTBF can be calculated as the arithmetic mean time between failures of a system.

Mean time between failures (MTBF) calculates the average time between failures of a piece of repairable equipment and can be used to estimate when equipment may fail unexpectedly in the future, or when it needs to be replaced.

MTBF is also used as a measure of performance, availability and reliability of systems, and to help with scheduling maintenance, inventory planning and system design.

2, The full form of MTBF is Mid-Term Budget Framework. It’s used on Governmental ,Census & Statistics in Worldwide

Medium-term budgetary frameworks (MTBFs) are defined as those fiscal arrangements that allow government to extend the horizon for fiscal policy making beyond the annual budgetary calendar. Although the approval of the annual budget law remains the key step in which important decisions on budgetary policy are adopted, most fiscal measures have budgetary implications that go well beyond the usual yearly budgetary cycle. As a result, a single year perspective provides a poor basis for sound fiscal planning. MTBFs usually cover the preparation, execution, and monitoring of multiannual budget plans and contain both expenditure and revenue projections as well as the resulting budget balances.

In general, medium term budgetary objectives included in a MTBF represent a weaker form of commitment than a pure rule incorporating binding targets. However, they may help ensure fiscal discipline by making more apparent the impact of current policies on the government balance in the coming years. Likewise, the existence of a MTBF may facilitate monitoring by providing benchmarks against which budgetary developments can be assessed over time. Overall, a well-designed MTBF should reflect the impact of past budgetary commitments as well as the future cost of new policy measures.

Finally, the strengthening of MTBFs can efficiently complement the introduction of other institutional reforms such as the introduction of an expenditure rule or top down budgeting.

3, The full form of MTBF is Mark Time Between Frames. It’s used on Technology ,Communication in Worldwide

This is a description of the DMX512 standard in short.

This standard is building on a line interface named RS-485 and it is a standard IC with almost al digital IC manufacture.

DMX512 sends packages of up to 512 frames with 8 bit data to fixtures.
Normally only the used addresses are send which means if only up to address 10 are used, only 10 frames are send.
The max number of frame that can be send is 512. (Start frame + 511)
Start Frame or Address 0 is a sync frame that can’t be addressed on the fixtures.
The packet don’t contain address information but the address is the frame position in the packet and therefore all frames up to the last frame are to be send each time.
To synchronize all receivers to the transmitter, a “Break” and a mark after break “MAB” is send.
Each receiver will from this “MAB” point, count frames and wait for the ones addressed to them.
Each frame ends with 2 high stop bits and the next frame starts with one low start bit.

The first frame (Address 0) will contain the start code and in normal operating mode it will be “0x00”.
