माहितीची देवाण व घेवाण कशी करावी या साठीच्या नियमावलीस काय म्हणतात ?

The correct answer is Option A (Protocol).

Key Points:
• In computer networking and data telecommunications, a Protocol (प्रोटोकॉल) is defined as a standardized set of rules and conventions that govern how data is formatted, transmitted, received, and acknowledged across a network.
• Protocols define syntax, semantics, synchronization, and error-checking mechanisms to ensure that heterogeneous computing systems can communicate without conflict.
• Common examples of networking protocols include TCP (Transmission Control Protocol), IP (Internet Protocol), HTTP, FTP, and SMTP.
• A Node is any physical connected device in a network, and the Internet is the global interconnection of networks.
• The official MPSC final answer key confirms Option 1 (Protocol).
• Key Takeaway: A formal set of rules governing the transmission and reception of digital data across a network is called a Protocol.
