Networking Device and Protocols
A network protocol is a standardized set of rules governing how data is formatted, transmitted, received, and interpreted across devices on a network. Think of it as the “language” that ensures different computers can understand each other—even with different hardware or software—and guarantees interoperability
2. Legacy Systems:
Still found in some older setups or niche environments where cost is a concern and performance isn’t critical.
Example: Connecting legacy industrial equipment in a factory.
Testing and Education:
Used in labs to demonstrate basic networking concepts or collision domains.
Example: Networking courses teaching Physical layer operations.
Temporary Networks:
Deployed in temporary setups (e.g., events) where simple connectivity is needed.
Example: Connecting multiple devices at a small conference booth.
