What Does Abstract Syntax Notation One Mean?

Abstract Syntax Notation One (ASN.1) is a standard for language defined in 1984 for data structures representing, encoding, decoding and transmitting data. They encapsulate a set of formal rules describing the structure of objects independent of a machine-specific encoding mechanism. It also removes ambiguities.

Techopedia Explains Abstract Syntax Notation One

ASN.1 is a widely used language with supporting tools. It specifies data structures independent of machines, which are directly integrated into tree and tabular combined notation and specification and description languages. While integration with the former enables direct testing of protocols defined using ASN.1, the latter enables specification of associated semantics for ASN.1 data structures. The application area for the standard appears in the structure definition of protocol messages.
