## Definition

the process in a computer network where one computer is chosen to be the boss or coordinator for the others. This helps the group of computers work together without getting confused.

For teachers: the process in distributed computing of designating a single node as the organiser or coordinator of tasks among a group of nodes. This mechanism ensures that only one node performs specific management actions, preventing conflicts and maintaining consistency across the network.

## Examples

- The system started a leader election after the main server crashed.
- When the primary database node failed, the remaining nodes initiated a leader election to choose a new coordinator.
- Efficient leader election algorithms are critical in distributed systems to ensure high availability and to prevent 'split-brain' scenarios where multiple nodes believe they have authority.

## Usage notes

- Commonly used in the context of distributed systems and network protocols.
