What is the difference between a centralized and distributed system?

A centralized system and a distributed system are two different approaches to organizing and managing computer systems. The main difference between them lies in how the system's resources and control are distributed.

In a centralized system, all the resources and control are concentrated in a single location or a central server. This means that all the processing, storage, and decision-making capabilities are handled by a central authority. The central server acts as a bottleneck, as all requests and data flow through it. This type of system is typically easier to manage and control, as all the components are located in one place. However, it can be a single point of failure, and if the central server goes down, the entire system may become inaccessible.

On the other hand, a distributed system is composed of multiple interconnected nodes or computers that work together to achieve a common goal. Each node in the system has its own processing power, storage, and decision-making capabilities. These nodes communicate and coordinate with each other to perform tasks and share resources. Distributed systems are designed to be fault-tolerant, as the failure of one node does not necessarily lead to the failure of the entire system. They can handle large amounts of data and provide scalability and flexibility. However, managing and coordinating the nodes in a distributed system can be more complex and challenging.

In summary, the main difference between a centralized and distributed system lies in the concentration of resources and control. A centralized system has all the resources and control in a single location, while a distributed system distributes resources and control across multiple interconnected nodes.
