Centralized systems Vs. Distributed systems

Centralized systems and distributed systems can be compared in deferent perspectives

1. Independent Memory vs. Shared memory

If independent systems method arguments can be passed easily, take (value,return), If distributed only value can be passed to the system.

2. Process Failures

In distributed systems process failure Vs. Network Failure difficult to distinguish

3. Clock architecture

In centralized events can be ordered but not in distributed.

4.
Link error can be distinguish from process Failures

Link may delay / packet loss / miss ordered

Are can’t be distinguish from

Process crash / reboot / miss behavior
