A bottleneck is the narrowed portion (neck) of a bottle near its opening, which limits the rate of outflow, or any object of a similar shape. The literal neck of a bottle was originally used to play what is now known as slide guitar. Metaphorically, the term may also be used as an analogy for any of the following implications of rate limitation ...
Bottleneck (engineering) This graphic shows the bottleneck that can arise between the CPU, memory controller, and peripherals. In engineering, a bottleneck is a phenomenon by which the performance or capacity of an entire system is severely limited by a single component. The component is sometimes called a bottleneck point.
In combinatorial optimization, a field within mathematics, the linear bottleneck assignment problem ( LBAP) is similar to the linear assignment problem. [1] In plain words the problem is stated as follows: There are a number of agents and a number of tasks. Any agent can be assigned to perform any task, incurring some cost that may vary ...
The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [1] The document describes a design architecture for an electronic digital computer with these components: The ...
A traffic bottleneck is a localized disruption of vehicular traffic on a street, road, or highway. As opposed to a traffic jam, a bottleneck is a result of a specific physical condition, often the design of the road, badly timed traffic lights, or sharp curves. They can also be caused by temporary situations, such as vehicular accidents.
Bottleneck (network) In a communication network, sometimes a max-min fairness of the network is desired, usually opposed to the basic first-come first-served policy. With max-min fairness, data flow between any two nodes is maximized, but only at the cost of more or equally expensive data flows. To put it another way, in case of network ...
If a bottleneck communication link offering data rate R is shared by "N" active users (with at least one data packet in queue), every user typically achieves a throughput of approximately R/N, if fair queuing best-effort communication is assumed. Packet loss due to network congestion. Packets may be dropped in switches and routers when the ...
Bottleneck (software) In software engineering, a bottleneck occurs when the capacity of an application or a computer system is limited by a single component, like the neck of a bottle slowing down the overall water flow. The bottleneck has the lowest throughput of all parts of the transaction path. System designers try to avoid bottlenecks ...
