Definition

Noun: - A network topology in which all network devices are connected to a single central cable (the bus): In this arrangement, all nodes (like computers or printers) are linked to one main communication line. Data sent by any device travels along this bus and can be received by all other devices, though only the intended recipient typically processes it.

Usage

• This term is used specifically in the field of computer networking to describe a physical layout or structure for connecting devices.
• It is often discussed in contrast to other topologies like star, ring, or mesh.

Examples

• Noun:
  • The office's older network used a bus topology, which made it difficult to add new computers without disrupting the connection.
  • In a bus topology, a break in the main cable can bring down the entire network segment.

Advanced Usage

• Logical vs. Physical: While 'bus topology' primarily refers to the physical layout of cables, the concept can also apply to logical network architectures where communication functions as if on a shared bus.
• Termination: A critical technical aspect of a physical bus topology is the requirement for terminators at each end of the bus cable to prevent signal reflection.

Variants and Related Words

• Bus Network (n): A network that implements a bus topology.
  • A bus network is simple to set up but can have performance issues with many devices.
• Network Topology (n): The general arrangement of elements in a communication network.
• Linear Bus Topology (n): Another name for the standard bus topology, emphasizing its straight-line structure.

Synonyms

• Linear topology: A synonym emphasizing the single, linear cable.
• Bus network configuration: A more descriptive synonym.

Related Phrases

• "To be arranged in a bus": Describes devices connected using this topology.
  • All the workstations in the lab are arranged in a bus.

Noun

1. the topology of a network whose components are connected by a busbar
