A distributed system is a network that consists of autonomous computers that are connected using a distribution middleware. They help in sharing different resources and capabilities to provide users with a single and integrated coherent network.

Features of Distributed Systems:

1. **Concurrency of Components**: In distributed systems, several components can run concurrently. This means that multiple processes can run at the same time without affecting each other.

2. **Lack of a Global Clock**: In distributed systems, all the processes that are running concurrently do not have access to a global clock. This means that they cannot tell the exact order in which events occur.

3. **Independent Failure of Components**: Each component in a distributed system can fail independently, without affecting the entire system. This is a crucial feature for building reliable systems.

4. **Geographical Distribution**: Components in a distributed system can be located physically close together or spread out over a network. This geographical distribution can help improve performance and reliability.

5. **Resource Sharing**: Distributed systems allow multiple users to access the same resources, which can be centrally controlled or distributed across a network.

6. **Scalability**: Distributed systems can easily be scaled up or down, by adding or removing resources without disrupting the entire system.

7. **Transparency**: Distributed systems are designed to hide their complexity from the user. This means that the user does not need to be aware of the underlying architecture, such as the location of resources, to use the system effectively.

8. **Openness**: Distributed systems are often designed to be open, meaning that they can be easily modified and extended. This allows for the integration of different types of systems and the addition of new components.
