Explanation:
d) Reliability
In distributed systems, reliability is often considered a challenge rather than an advantage. While distributed systems offer many benefits such as scalability, resource sharing, and incremental growth, ensuring reliability can be more complex due to the distributed nature of the system.
Reliability refers to the ability of a system to consistently perform its functions correctly and without failure over time. In distributed systems, various factors can affect reliability, including network failures, communication delays, hardware failures, and software bugs. Coordinating and managing these factors across multiple nodes or components in a distributed environment can be challenging.
While measures can be taken to improve reliability in distributed systems, such as redundancy, fault tolerance, and error handling
