What is communication in distributed system?
Communication between two processes in a distributed system is required to exchange various data, such as code or a file, between the processes. When one source process tries to communicate with multiple processes at once, it is called Group Communication.
What is architecture of distributed system?
In distributed architecture, components are presented on different platforms and several components can cooperate with one another over a communication network in order to achieve a specific objective or goal. It provides a buffer between the applications and the network.
What are the main concepts of a distributed system?
A distributed system has several characteristics: its components are autonomous, schedul- ing and other resource management and security policies are implemented by each system, there are multiple points of control and multiple points of failure, and the resources may not be accessible at all times.
How do client and server processes communicate in a distributed system?
Client-server concept underpins distributed systems over a couple of decades. In practice there are often multiple clients and single server. Clients start communication by sending requests to the server, the server handles them and usually returns responses back.
What are the main components of the architecture of a distributed system?
2) Distributed System Architectures
- Component: A modular unit with well-defined interfaces; replaceable; reusable.
- Connector: A communication link between modules which mediates coordination or cooperation among components.
What are the types of distributed systems architecture?
The use of different configurations of components and connectors leads us to four main architectural styles for distributed systems:
- Layered architecture.
- Objects-centered/SOA architecture.
- Resource-based architecture.
- Events-centered architecture.
What are design issues in distributed system structure?
A distributed system is defined as a collection of autonomous computers linked by a network with software designed to produce an integratedcomputing facility….
| Q. | What are design issues in distributed system structure? |
|---|---|
| A. | scalability |
| B. | fault-tolerance |
| C. | clustering |
| D. | all of the mentioned |
What are the main objectives and challenges of distributed systems?
The main goal of a distributed system is to make it easy for users to access remote resources, and to share them with other users in a controlled manner. Resources can be virtually anything, typical examples of resources are printers, storage facilities, data, files, web pages, and networks.
What is the communication provided by Client Server?
The client server relationship communicates in a request–response messaging pattern and must adhere to a common communications protocol, which formally defines the rules, language, and dialog patterns to be used. Client-server communication typically adheres to the TCP/IP protocol suite.
What is multicast communication in distributed system?
Multicast is the communication where one host sends data to multiple hosts at once.
What is the basic architecture of the distributed control system?
The basic architecture of the distributed control system, as shown: The DCS consists of an operator station, a control station, and a communication system. The operator station collects data relating to the process operation and can display and manipulate those data.
What do you need to know to understand distributed systems?
Understanding distributed systems requires a knowledge of a number of areas including system architecture, networking, transaction processing, security, among others.
What is a Distributed Object Architecture?
There is no distinction in a distributed objectarchitectures between clients and servers. Each distributable entity is an object that providesservices to other objects and receives services fromother objects. Object communication is through a middlewaresystem called an object request broker.
What is the application development for distributed systems?
Although developing applications for a distributed system is similar to developing for non-distributed systems, the application development chapter discusses certain issues that can affect an application in a distributed system. It also documents Oracle’s support for X/Open’s XA Library.
