Erlang is a programming language designed for building robust, concurrent, and fault-tolerant systems. It was initially developed in the 1980s by Ericsson, a Swedish telecommunications company, primarily for use in telephony applications. Erlang takes its name from Agner Krarup Erlang, a Danish mathematician who made significant contributions to the field of telecommunications.
Erlang is known for its built-in support for concurrency, distribution, and fault tolerance. It provides a lightweight concurrency model based on the actor model, where each concurrent unit of execution is called a process. These processes communicate with each other by message passing, allowing for highly scalable and responsive systems.
