Concurrency is a property of systems in which several computations are executing simultaneously, and potentially interacting with each other.<ref>Jiacun Wang, 2017. Real-Time Embedded Systems. Wiley. p. 12. {{ISBN|978-1-119-42070-5}}.</ref> A number of mathematical models have been developed for general concurrent computation including [[Petri net]]s, [[Process calculus|process calculi]] and the [[Parallel random-access machine|Parallel Random Access Machine]] model.<ref>Gordana Dodig-Crnkovic; Raffaela Giovagnoli; 2013. Computing Nature: Turing Centenary Perspective. Springer Science & Business Media. p. 247. {{ISBN|978-3-642-37225-4}}.</ref> When multiple computers are connected in a network while using concurrency, this is known as a distributed system. Computers within that distributed system have their own private memory, and information can be exchanged to achieve common goals.<ref>Simon Elias Bibri; 2018. Smart Sustainable Cities of the Future: The Untapped Potential of Big Data Analytics and Context-Aware Computing for Advancing Sustainability. Springer. p. 74. {{ISBN|978-3-319-73981-6}}.</ref> | |||
