- 2. Communication in distributed system Click icon to add picture Definition Communication in distributed system refer to the exchange of the information between the processes in the system that are geographically dispersed or logically separate.
- 4. Click icon to add picture Communication protocols: 1. TCP/IP(Transmission control protocol/Internet protocol): A suite of protocols for reliable communication. 2. UDP(User data gram protocol): A protocol for best effort delivery. 3. HTTP(Hypertext transfer protocol): A protocol for the request response communication.
- 5. Click icon to add picture Communication models: 1. Client server model: A centralized model where clients request services from a server. 2. peer to peer model: A decentralized model where nodes act as both client and servers 3. Publish subscribe model: A model where nodes publish messages to a topic and subscribers receive messages..

- 7. • Remote procedure call (RPC). • Definition: • remote procedure call is a communication protocol that allows a program to call procedures or methods or another program over network. • RPC Types: • Synchronous RPC • Asynchronous RPC
- 9. Click icon to add picture RPC Architecture Client: The program that makes RPC request. Server: The program that provides the RPC services. RPC Runtime: the infrastructure that manages the RPC communication.
- 10. •RPC Benefits • Modularity: • RPC promotes modularity by allowing programs to be broken down into smaller independent components. • Reusability: • RPC enable the code reusability by allowing the procedures to be shared across program. • Distributed computing: • RPC enable distributed computing by allowing the programs to communicate over a network.
- 11. Message passing • Message passing is the fundamental concept in the computer science and distributed systems. • Types of message passing: • Synchronous message passing: The sender waits for the receiver to acknowledge the message before continuing. • Asynchronous message passing: the sender continues executing without waiting for the receiver acknowledgment.
- 13. Click icon to add picture Message passing techniques: Message queues: Message are stored in the queue before being processed by the receiver. Remote procedure call (RPC): Message are used to invoke procedures on the remote processes. Message streaming: Message are sent in continuous stream allowing for real time communication.
