It often refers to networks that are overloaded, which is caused by the inability of the hardware and transmission channels to support the traffic. It can also refer to a mismatch inside the computer where slower-speed peripheral buses and devices prevent the CPU from being used to its fullest capacity.bottleneck
A marked decrease in gene pool diversity due to a low number of genetically distinct individuals in the population, i.e., a population bred from 2 individuals has far fewer variables on the allelic loci—a bottleneck—than a second population bred from hundreds of individualsbottleneck a period in the history of a population during which the number of individuals is reduced to a low number, perhaps by disease or extreme environmental conditions. As a result RANDOM GENETIC DRIFT may occur in the population. See also FOUNDER EFFECT.bottleneck
BottleneckIn project management and other fields, a situation in which output is limited by the lowest capacity system in the project. For example, the output of book publishing is limited by how quickly writers write, regardless of how quickly books can be edited and printed. Bottlenecks have a wide variety of applications in business, technology and elsewhere.bottleneck a hold-up in some part of a PRODUCTION LINE which disrupts the smooth flow of work.
