This approach distributes the workload across a network of computers, enhancing performance, scalability, and reliability. The key concepts and benefits of distributed processing: 1. Concepts:  Parallel Processing: Distributed systems divide tasks into smaller subtasks that can be processed simultaneously by different nodes. This parallelism improves overall system performance and reduces execution time.  Interconnected Systems: Nodes in a distributed system are interconnected through a network, enabling seamless communication and data exchange. Common network architectures include client-server models and peer-to-peer networks.  Load Balancing: Distributed processing involves distributing tasks evenly among nodes to ensure optimal resource utilization and prevent bottlenecks. Load balancing algorithms dynamically adjust the distribution of tasks based on system conditions. 2. Benefits:  Scalability: Distributed systems are inherently scalable, allowing organizations to easily expand their computing capacity by adding more nodes to the network. This 8 UNIT 02: Computers in Organization scalability ensures that the system can handle increasing workloads without a significant drop in performance.  Fault Tolerance: Distributed processing enhances system reliability by reducing the impact of hardware failures or network issues. If one node fails, other nodes can continue processing tasks, minimizing downtime and data loss.  Resource Utilization: Efficient distribution of tasks across multiple nodes optimizes resource utilization, preventing individual nodes from being overwhelmed. This results in better use of processing power, memory, and storage.  Improved Performance: Parallel processing and load balancing contribute to improved system performance, allowing tasks to be completed more quickly. This is particularly beneficial for computationally intensive applications and large-scale data processing.  Geographical Distribution: Distributed systems can be geographically distributed, allowing organizations to have computing resources in multiple locations. This facilitates global collaboration, reduces latency, and enhances user experience.  Cost-Effective: Distributing tasks across existing hardware resources can be more cost-effective than investing in a single, powerful centralized system. It allows organizations to leverage the capabilities of existing hardware and adapt to changing computing needs. 3. Challenges:  Data Consistency: Ensuring consistent data across distributed nodes can be challenging. Distributed databases and protocols are employed to address this issue.  Communication Overhead: Communication between nodes introduces overhead, and network latency can impact performance.
