Definition Process resilience in distributed systems refers to the ability of processes to continue functioning correctly despite failures. Groups are collections of processes that work together to

a) Bully Algorithm - Definition: A distributed algorithm used to elect a coordinator (leader) among processes in a distributed system. - Key Points: - The process with the highest ID becomes the

Role of a Coordinator - A coordinator is a special process in a distributed system responsible for managing and coordinating tasks among processes. - Key Roles: 1. Process Coordination: Ensures

Middleware Definition Middleware is software that connects distributed applications and components, hiding the complexity of the underlying network and hardware. - Facilitates communication, intero

Distributed Commit Definition A distributed commit is a protocol that ensures all participants in a distributed transaction either commit or abort the transaction consistently. - Prevents inconsist

Definition An Election Algorithm is a protocol used in distributed systems to select a coordinator (leader) among processes. - Ensures that exactly one process acts as the coordinator at any time.
