Concept in Definition ABC

Buffer is for the computing the temporary memory that allows the start of a program or file that needs information, it can store it until finishing its work, thus being able to avoid permanent stops due to the possible lack of data.

It is common to notice the work of the buffer when opening a multimedia file that requires loading the data in sufficient quantity to be able to function without stopping. This happens when opening a song, movie, or video that involves using temporary memory. According to availability memory or buffer of each device, the task may take more or less time. It is also very common to resort to the buffer or temporary memory when it is necessary to send files outside the computer, for example to the printer, to a speaker or to a telecommunications network. It can be applied to both hardware and software, although the latter option is usually the most common.

Other elementary functions of the buffer memory (perhaps not so visible) are for example those that have to do with the correct

functioning of keyboard. It requires minimal buffer memory to store and display user-typed characters almost immediately. Similarly, buffer memory is essential when talking about connections via Internet that require permanent access to this memory in order to reproduce images or videos continuously and without pauses.

Unlike the cache (which also uses the storage data), it is assumed that all data stored by the buffer will eventually be used while the cache can save information for a single time without it being necessary in another moment. Clearly, to obtain the best results it is of great importance to have buffer memories of sufficient capacity according to your own needs and preferences since a small buffer memory may not be enough for large requirements of storage.
