What are Distributed Systems?
Distributed systems are networks of independent computers that work together to perform complex tasks. These systems appear as a single cohesive unit to users, even though the processing is spread across multiple physical machines. This structure allows distributed systems to handle large-scale computations efficiently and reliably.
Key elements of distributed systems include:
- Transparency: Distributed systems are designed to hide the complexity of processes from the user. This makes the system appear as a single entity, despite being a collection of independent components.
- Scalability: These systems can easily be scaled up by adding more machines. Scalability improves performance and accommodates growth without disrupting existing operations.
- Fault Tolerance: Distributed systems are resilient to failures. If one component fails, the system can reroute tasks or replicate data to continue functioning without significant downtime.
- Resource Sharing: Computers in a distributed system share resources such as processing power and data storage. This sharing is managed seamlessly to enhance overall system efficiency.
- Decentralization: Unlike traditional centralized systems, distributed systems do not have a single central controller. Decisions and control are often spread across various nodes, which enhances flexibility and resistance to attacks.
Difference Between Computer Networks and Distributed Systems
A computer network is a group of interconnected computers that share resources and data. Distributed systems, while similar, consist of autonomous computers working together to perform tasks. These systems form the backbone of modern digital communication and processing. Yet, they serve different purposes and operate under different principles. In this article, we will explore the differences between computer networks and distributed systems.
