A computer system is a collection of hardware and software components designed to provide an effective tool for computation. Computer system are used in every walk of life to assist us in the various tasks we perform. The wide availability of the internet has enhance the use of computer for information sharing and communication. Computer system allows us to store, process, display and communicate information. In any modern computer system even a simple one, in general needs several different programs in order to accomplish its various functions.

Erlang language

Erlang is a declarative language for programming concurrent and distributed systems which was developed by the authors at the Ericsson and Ellemtel Computer Science Laboratories.

The first version was developed by Joe Armstrong in 1986. It was originally a proprietary language within Ericsson, but was released as open source in 1998.

Erlang belongs to the family of pattern-matching languages, which amounts to tons ofnstructural tests and value tests being done all the time in Erlang code.

The name of Erlang attributed to Agner Krarup Erlang (1878–1929) was a Danish mathematician who developed a theory of stochastic processes in statistical equilibrium.

This programming is a general-purpose concurrent, garbage-collected programming language and runtime system. The sequential subset of Erlang is a functional language, with strict evaluation, single assignment, and dynamic typing.

Concurrency is explicit and the user can precisely control which computations are performed sequentially and which are performed in parallel.
