Bus Topology
IEEE 802.3 · 10BASE-2 / 10BASE-5
All devices share a single cable segment (the backbone). Each device connects to the backbone via a short stub cable. Data sent by any node propagates in both directions along the backbone until it reaches a terminator, where it is absorbed.

REAL-WORLD EXAMPLES
HOW PACKET TRAVELS
Source node puts signal on backbone → signal propagates to both ends → destination node reads its addressed frame → terminators absorb remaining signal.
