Answer:
Advantages of Distributed Systems over Centralized ones
1:Incremental growth:Computing power can be added in small
increments
2:Reliability:If one machine crashes, the system as a whole can
still survive
3:Speed:
A distributed system may have more total computing power than a
mainframe
4:Open system:
This is the most important point and themost characteristic point
of a distributed system.
Since it is an open system it is always ready to communicate with
other systems.
an open system that scales has an advantage over a perfectly closed
and self-contained system.
Economic:ANd Microprocessors offer a better price/performance than
mainframes
Disadvantages of Distributed Systems over Centralized ones
1:As i previously told you distributed systems will have an
inherent security issue.
2:Networking:If the network gets saturated then problems with
transmission will surface.
3:Software:There is currently very little less software support for
Distributed system.
4:Troubleshooting:Troubleshooting and diagnosing problems in a
distributed system can also become more difficult, because the
analysis may require connecting to remote nodes or inspecting
communication between nodes.

Centralized databases offer easier management and maintenance due to a single point of control, while distributed databases provide better scalability, fault tolerance, and performance due to data distribution. Centralized databases are simpler to design and enforce consistency but can become a single point of failure, whereas distributed databases can continue functioning even if some nodes fail but are more complex to manage and balance data distribution. Both approaches have their own strengths and weaknesses depending on the specific requirements of the system.
