  The Buffer Zone | Linux Magazine
Each buffer holds a single kind of Java primitive (in a sense, each buffer has a "type"), and maintains its own state, including its maximum capacity and the position of the next read or write.
If you create a new buffer from an entire array, the buffer's capacity and limit will be the same as the number of elements in the array, and position will be set to 0.
It sets the limit to the capacity of the buffer, moves the position to 0, and clears the mark.

  Buffer state - Wikipedia, the free encyclopedia
A buffer state is a country lying between two rival or potentially hostile greater powers, which by its sheer existence is thought to prevent conflict between them.
The conception of buffer states is part of the theory of balance of power that entered European strategic and diplomatic thinking in the 17th century.
In the 19th century, the manipulation of buffer states like Afghanistan and the Central Asian emirates was an element in the diplomatic "Great Game" played out between Britain and Tsarist Russia for control of the approaches to strategic mountain passes that led to British India.

During a first mode of operation of the tri-state circuit, the logic state of the output produced by a buffer circuit included in the tri-state circuit is determined in response to the logic state of the input signal to the buffer circuit.
During a second mode of operation of the buffer circuit, the output of the buffer circuit is in a high- impedance condition, or high Z, state independent of the logic state of the input signal to the buffer circuit.
Stated differently, the control circuit 50 generates a control signal, or enable, causing the buffer circuit to selectively operate in one of the first and second modes of operation.

 Adobe - Developer Center : Implementing a dual-threshold buffering strategy in Flash Media Server
At time T1 the buffer is full; therefore movie starts to play and the buffer is kept full by a bandwidth greater than that required by the stream (available bandwidth greater than 100%).
As you can see from this standard, static buffering method, if bandwidth decreases under the required value, the buffer may be insufficient to compensate for the bandwidth drop and one or more rebuffering sessions may be necessary to deliver the streaming.
Dual-threshold buffering assures a better allocation of excess bandwidth because it uses it to expand the buffer to a final, higher value while playing the movie at the same time.

Moreover, the buffer 2 comprises an address generator 22 which is adapted to generate a first address signal 24 and a second address signal 26, both of which are applied to the memory 20.
In the second state, the second address register skips a number of locations in the memory 20 at each clock pulse of the second clock signal 10, such that each time N locations of M consecutive locations in the memory 20 are addressed.
The buffer 2 is adapted to repeat the supply of the first television image at the output 6 each time from a group of 3 television images received at the input 4.

The buffer object ID zero is reserved, and when buffer object zero is bound to a given target, the commands affected by that buffer binding behave normally.
While a buffer object is bound, GL operations on the target to which it is bound affect the bound buffer object, and queries of the target to which a buffer object is bound return state from the bound object.
Bindings to that buffer in other contexts and other threads are not affected, but attempting to use a deleted buffer in another thread produces undefined results, including but not limited to possible GL errors and rendering corruption.

 Buffer Strips: Common Sense Conservation | NRCS
Buffers include: riparian buffers, filter strips, grassed waterways, shelterbelts, windbreaks, living snow fences, contour grass strips, cross-wind trap strips, shallow water areas for wildlife, field borders, alley cropping, herbaceous wind barriers, and vegetative barriers.
Buffers also trap fertilizers, pesticides, pathogens, and heavy metals, and they help trap snow and cut down on blowing soil in areas with strong winds.
Conservation buffers are a visual demonstration of your commitment to land stewardship.

 What's a Tri-state Buffer?
A tri-state buffer is a useful device that allows us to control when current passes through the device, and when it doesn't.
Recall (from earlier) that a common way for many devices to communicate with one another is on a bus, and that a bus should only have one device writing to it, although it can have many devices reading from it.
A tri-state buffer is a device that allows you to control when an output signal makes it to the bus.

State 5, for instance, signifies that there are five packets in the buffer.
In figure 2, state transitions occur each time a packet is removed from the buffer for playout.
If the buffer is in state i and no packets arrive during the packet playout period, the buffer will transition to state i-1.

 What's a Tri-state Buffer?
There are buffers which do not have a control input.
Tri-state buffers allow us to control which device outputs its value to the bus, by allowing us to selectively control the control bit of the tri-state buffer.
Usually, we use 32-bit tri-state buffers, which have 32 data inputs, 32 outputs, but a single control bit.

 Scenario 3
In order to handle this scenario, we assume as Steinbach does that the good periods in the channel last long enough so that the buffer is able to regain its target level by the time a bad period begins [1].
Our departure from the previous work, however, is that while Steinbach's analysis assumes that the buffer is at the target level when burst begin, we assume that since the channel has been in the good state for a long time, the buffer is in the steady state distribution for the good state.
In Steinbach's analysis, the buffer is deterministically in the target state at the beginning of the burst and empties (also deterministically) at the rate of playout.

 Buffers
In many cases an implementation has to decompress the buffer, converting the uncompressed data to a canonical internal format, and resample it into the format native to the current context.
The states described in this section are not exposed through the API (can not be queried, or be set directly), and the state description used in the implementation might differ from this.
The Buffer state is dependent on the state of all Sources that is has been queued for.

 Isamode - 3. Proof state
If a proof state buffer is active, these sequences will be stripped from the output and used to update the buffers contents.
In the proof state buffer, the cursor usually appears opposite one of the subgoals in the list (if there are any).
You may discover that very large proof states sometimes fail to parse and end up in the Isabelle buffer, instead of the proof state buffer.

Particularly with the non-Nvidia distributions where the state becomes AL_STOPPED, in some of the bad cases, I end up playing the final buffer twice (because I have to call alPlaySource again to handle the underflow) because I thought I still needed to play one more buffer, but it turns out I had already played it.

In 1816, after the year-long Anglo-Nepali ‘Gurkha War’, a British resident (government representative) was stationed in Kathmandu and the kingdom became a British-dependent buffer state.
The country was recognized as fully independent by Britain in 1923 although it remained bound by treaty obligations until 1947, the year of India's independence.
The government sought an extension of a state of emergency following the attacks, and the army responded by killing over 100 Maoist guerrillas in an offensive against the rebels on 25 February.

This series could continue, but these five examples best show what I was talking about in the first post: buffer states play a key role in the geopolitical strategy, and can do much to prevent wider conflict, although smaller states often end up as pawns in the games of greater states.
The reason many of these states exist in their present form is because they were colonial administrative units, and because the various European empires allowed free migration within these units.
That said, I think there is some value to be had from buffer states: if the buffer is armed and in good health (relevant to Switzerland and Thailand, I believe), then the buffered states essentially receive protection from each other for free.
