A data buffer is temporary storage for data being moved from memory to satisfy a query. It processes requests in a logical sequence and performs writing and reading tasks simultaneously. Buffers are used in telecommunications, corporate networks, and simple tasks like retrieving documents to prevent data corruption during transfer.
A data buffer is a section of memory in a computer that is intended to provide a temporary storage place for data as it is in the process of being moved from memory in order to satisfy a query initiated by a user. In a sense, this means that the buffer creates a temporary place for the data so that it can be processed logically and eventually be used to satisfy that query. This is an important feature, as the presence of the buffer helps minimize the risk of data damage during movement.
One of the basic mechanisms found with a data buffer is the fact that information is processed in a logical sequence. This is sometimes referred to as “first in first out” or FIFO buffering. Rather than allowing the system to become overwhelmed with multiple requests, the buffer essentially lines up all requests in the order they are received, processes the first request, and then moves on to the next request in the queue. End users are rarely aware of this process, as requests are handled so quickly that the system appears to be handling multiple tasks at once.
As part of the process, a data buffer performs two key tasks simultaneously. A task involves writing data to the buffer zone of memory in preparation for answering a query. The second task is focused on reading the data, using protocols that help ensure that the flow of information is organized correctly. Typically, the write function proceeds at one speed while the read function occurs at a different speed which helps the two processes work in tandem without causing transfer issues.
The use of a data buffer is common to many types of computer-based functions. In the telecommunications world, buffers help process audio and other data flows between points, using read and write functions to keep transmissions organized and concise. With data communication within a corporate network, buffers help to handle huge amounts of data without corruption of any information while transmitting from a memory storage area to the end user. Even with simple tasks like retrieving documents saved on a hard drive, data buffering makes sure that the information contained in that saved file is protected from corruption during transfer and the user will be able to view and work with the document without trouble.
