संगणका द्वारे होणाऱ्या संदेश वहन नियंत्रण नियमावलीस काय संबोधले जाते ?

The correct answer is Option A (Protocol).

Key Points:
• The correct option is (1).
• Core Networking Principles:
• In computer science and telecommunications, a 'Protocol' is a formally defined set of standardized rules, conventions, and data formats that govern how data is transmitted, received, and interpreted across a communication network.
• Essential functions of network protocols include:
• Addressing and Routing (e.g., IP)
• Error detection, correction, and flow control (e.g., TCP)
• Handshaking and synchronization between heterogeneous hardware and software environments
• Classic examples include TCP/IP, HTTP, HTTPS, FTP, and SMTP.
• Clarification of incorrect options:
• Controller: A hardware chip or software driver governing physical device interactions.
• Processing: The execution of algorithmic instructions by the central processing unit (CPU).
• Key Takeaway: A protocol is the formal set of rules and communication procedures governing network data transmissions.
