Amdahl's lawIn computer architecture, Amdahl's law (or Amdahl's argument) is a formula limiting the speedup of a task as resources are added to the system executing that task. The law can be stated as: the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used. It is named after computer scientist Gene Amdahl, and was presented at the American Federation of Information Processing Societies (AFIPS) Spring Joint Computer Confere...APIAn application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build such a connection or interface is called an API specification. A computer system that meets this standard is said to implement or expose an API. The term API may refer either to the specification or to the implementation.
