External synchronization in a distributed system refers to the coordination and timing of operations across different nodes or components to ensure consistency and coherence of data. It typically involves mechanisms like clocks, timestamps, or consensus algorithms to align the states of distributed processes. This is crucial for maintaining data integrity when multiple nodes may access or modify shared resources simultaneously. External synchronization helps prevent issues such as race conditions and ensures that events are perceived in a consistent order by all participants in the system.

What is internal synchronization in distributed system?
Internal synchronization in a distributed system refers to the mechanism through which processes or nodes coordinate their actions to ensure consistency and order in the system. This can involve using techniques like mutual exclusion, barriers, or message ordering to manage concurrent access to shared resources and maintain data integrity across the distributed environment. Internal synchronization helps prevent race conditions and ensures that operations are carried out in a predictable and controlled manner.
How clock synchronization occurs in a distributed system?
Clock synchronization in a distributed system is achieved by using algorithms like NTP (Network Time Protocol) or PTP (Precision Time Protocol) to ensure that all clocks in the system are adjusted to a common time reference. This helps in maintaining consistency and coordination among different nodes in the distributed system. By periodically updating and correcting the local clocks based on a reliable time source, synchronization is maintained across the system.
What are the characteristics of distributed operating system?
the characteristics of distributed systems are 1. Heteroginity 2. Openess 3. security 4. transparency 5. concurrency 6. failure handling 7. scalability by sagar prajapati
Synchronization in operating system?
Synchronization in an operating system refers to the coordination of the events in order to operate a given operating system.
What do you mean by synchronization in operating system?
synchronization mean arrange all process in sequence for that not occured no colusion in the system.
What are the limitations of the distributed system?
1. Absence of global clock... so that no synchronization among processes. 2. Absence of dynamic memory.... So at a particular time a process can only get partial & coherent state Or complete & incoherent state of the distributed system. Coherent:- recorded state of all the processes at any given time
What is the strength of a circular flow chart?

What is the artery distributed throughout the head?
external carotid
What is the role of threads in distributed system?
In a distributed system, threads play a crucial role in enabling concurrent execution of tasks across multiple processes or nodes. They allow for efficient resource utilization by enabling multiple operations to run simultaneously within a single process, thereby improving responsiveness and throughput. Threads facilitate communication and synchronization between distributed components, helping to manage workloads and ensure proper coordination. Overall, they enhance the performance and scalability of distributed applications by allowing parallel processing and reducing latency.
Difference between distributed system and multiprocessor system?
The difference between distributed system and multiprocessor system is whether the processing units in the system share the main memory. If yes, then the system is multiprocessor system; otherwise, it's a distributed system.
