• Early standard used to connect modems to computers.
• Revisions: Evolved over time.
• Electrical Component: Defined by V.28 standard.
• Mechanical Component: Often follows ISO 2110 for the DB-25 connector (with DB-9 now more common).
• Functional & Procedural Components: Defined by V.24 standard (e.g., pin functions on DB-9 connector).
