Introduction to Distributed Computing
Distributed computing is a type of computing system where processing and data storage is spread across multiple devices or systems, rather than being handled by a single central device. This type of system is made up of individual devices or systems that are connected and work together to perform tasks, share resources, and provide data and computing power.
# Examples of Distributed Computing
One example of a distributed computing system is cloud computing, where resources are delivered over the Internet and accessed on demand. Other examples of distributed computing include peer-to-peer networks, grid computing, and distributed databases.
Components
Devices and Systems:
The foundation of a distributed computing system is the devices and systems that are connected together. Each has its own processing capabilities and can manage and store its own data.
Network Connectivity:
A network is needed to connect the devices and systems in a distributed computing system. This allows them to communicate and exchange data with each other.
Resource Management:
Resource management is an important part of distributed computing systems, as it allocates and manages shared resources such as computing power, storage, and networking.
Peer-to-Peer Architecture:
Most distributed computing systems use a Peer-to-Peer Architecture, where devices or systems can act as both clients and servers and communicate directly with each other.
Characteristics
1. Multiple Devices or Systems for Distributed Computing
A distributed computing system is composed of multiple devices or systems that are connected to each other to share resources and processing power. The distributed computing system can consist of physical machines, virtual machines, or a combination of both.
2. Peer-to-Peer Architecture for Distributed Computing
In a distributed computing system, devices or systems can act as both clients and servers. This is because they can both request and provide services to other devices or systems in the network. This is known as a peer-to-peer architecture, as each device or system is both a consumer and a producer of services.
3. Shared Resources for Distributed Computing
In a distributed computing system, resources such as computing power, storage, and networking are shared among the devices or systems in the network. This allows for efficient utilization of resources and increases the scalability of the system.
4. Horizontal Scaling for Distributed Computing
Scaling a distributed computing system typically involves adding more devices or systems to the network to increase processing and storage capacity. This is known as horizontal scaling, as the system can scale horizontally by adding more machines or systems to the network. Horizontal scaling can be achieved through hardware upgrades or by adding additional devices or systems to the network.

Applications
Cloud Computing
Cloud Computing is a distributed computing system that enables users to access computing power, storage, and networking resources over the Internet. It allows users to access resources from any connected device, and provides scalability, reliability, and cost-effectiveness. Cloud Computing is widely used for applications such as data storage, web hosting, software development, and business applications.
Peer-to-Peer Networks
Peer-to-Peer Networks are a type of distributed computing system that enables users to share and exchange resources such as files and computing power. It enables users to connect directly with each other and share resources, eliminating the need for a central server or intermediary. Peer-to-Peer Networks are used for applications such as file sharing, distributed computing, and distributed gaming.
Distributed Architectures
Distributed Architectures are a type of distributed computing system that enables applications to be distributed across multiple devices or systems. This type of architecture provides scalability, fault tolerance, and high availability by distributing the load and data storage across multiple resources. Distributed Architectures are used for applications such as microservices architectures, web services, and distributed databases.
