Web- [Instructor] A buffer solution consists of a significant amount of a weak acid and its conjugate base. Let's say we have a generic weak acid, HA, and its conjugate base, A-. And we're gonna use some particulate diagrams to try to understand how buffers work. So for our first particulate diagram, let's count out how many particles we have of each. WebBuffers can be implemented in a fixed memory location in hardware—or by using a virtual data buffer in software, pointing at a location in the physical memory. In all cases, the data stored in a data buffer are stored on a physical storage medium.
