Memory overcommitment is a concept in computing that covers the assignment of more memory to virtual computing devices (or processes) than the physical machine they are hosted, or running on, actually has. This is possible because virtual machines (or processes) do not necessarily use as much memory at any one point as they are assigned, creating a buffer.
