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

Aspect | Details |
Function | Connects devices in a LAN, broadcasting data to all ports. |
Operation | Receives signals, amplifies, and broadcasts to all connected devices; uses CSMA/CD for collisions. |
Protocols | IEEE 802.3 (Ethernet), 10Base-T, 100Base-T. |
Devices | Netgear EN104, D-Link DE-805TP, 3Com OfficeConnect. |
Layer (OSI) | Physical (Layer 1). |
Layer (TCP/IP) | Link Layer (Physical component). |
Use Cases | Small LANs, legacy systems, educational labs. |
Limitations | Single collision domain, half-duplex, no filtering, obsolete. |
