Buffer
Buffer is an English term that is not part of the dictionary of the Royal Spanish Academy (RAE) but that has a frequent use in our language. In the field of electronicsa buffer is a device that is used to avoid loading effect (also known as regulation) in a circuit.
The buffer, in this sense, is a operational amplifier which works like follower and that allows to compensate the current losses through the voltage of your power supply.

buffering in computing
For the computinghe data buffer is the memory location of a digital device or a computer which is reserved for temporary storage of information. While the data is in the buffer, it is waiting to be processed.
This type of buffer has currently become one of the essential elements that all computers have and, therefore, a fundamental part of our day to day since we use them both for work and for simple leisure. Specifically, the reason that explains the importance of the buffer in these devices is that thanks to it you can perform actions such as listening to different music on speakers, receiving and sending various data over the Internet or acting as a storage mechanism.
Sometimes the former is often confused with the disk cache but, although both can function as their opposite, the former is characterized by the fact that it allows the stored data to be saved and used to reduce the user’s waiting time.

streaming
An example of buffering occurs when trying to run audio or video applications directly from Internetwithout downloading them to the computer.
This practice, known as streamingrequires the use of a buffer to reduce the risk of playback being cut off due to bandwidth problems.

buffer in chemistry
In the area of the chemistrya buffer is a system formed by a weak acid and its conjugate base (or vice versa) which opposes large variations in pH in an aqueous solution.
A chemical buffer is also known as one in this mentioned scientific field that, among other things, is identified because it has its own effective PH range. This, for its part, will be closely related to the balance of the acid that has been used.
Specifically, said characteristic will proceed to be obtained by calculation. To do this, in most cases, the so-called Henderson–Hasselbalch equation. This is based on the acidity constant, the salt concentration, the lactic acid…
There are many types of chemical buffers that exist, as would be the case, for example, of acetic acid-acetate anion. And all this without forgetting that in the human body there are other equally significant ones such as phosphate, bicarbonate, amino acids, hemoglobin or proteins.

The term in a GIS
Finally, the concept appears associated with a Geographic information system (NEXT or in English, CHALK by Geographic Information System).
In this case, it is the polygon that frames the area of influence that results from taking a certain distance from a point, line, or other polygon.
