Correct option is B
In a Bus Topology, all devices (stations) are connected to a single central cable, known as the bus or backbone. When a device transmits data, the signal travels in both directions along the bus, and all devices on the network receive the signal. However, only the intended recipient processes the data; the rest ignore it.
This is a linear architecture because the cable forms a single line, and data is broadcasted to all devices connected to it.
Important Key Points:
- Bus topology uses a single communication line shared by all nodes.
- It is easy to implement and requires less cable than star or mesh topologies.
- A terminator is needed at each end of the bus to prevent signal reflection.
Knowledge Booster:
- Mesh Topology: Each node is directly connected to every other node, offering high redundancy but not linear.
- Star Topology: All nodes are connected to a central hub or switch; not a linear broadcast medium.
- Cell Topology: Not a standard LAN topology — often relates to wireless cellular networks, not wired LANs.
