Redundancy in distributed systems refers to the duplication of critical components or data to ensure reliability and availability. It is used to prevent single points of failure, allowing the system to continue operating smoothly even if some components fail. By having multiple instances of data or services, redundancy enhances fault tolerance and improves overall system resilience, ensuring that users experience minimal disruption. This is crucial in environments where uptime and data integrity are paramount.

What is difference between the data validation and data redundancy?
one is a validation the other is redundancy clue is in the name
Is Redundancy in databases a desirable characteristic?
yes
What are the disadvantages of data redundancy?
with data redundancy there willbe more wastage of memory space as same type of data willbe saved many times when to want to see the data all duplicate results will come
Data redundancy produces what?
Data redundancy produces unnecessary duplication of data within a database or system, which can lead to increased storage costs and potential inconsistencies. When the same data exists in multiple locations, it can create challenges in maintaining data integrity and accuracy. Additionally, redundant data can complicate data management and retrieval processes, making it harder to ensure that users access the most current and reliable information.
What is the difference between data redundancy and data inconsistency?
Redundancy is data that is not needed or no longer needed. Inconsistency is where you have different data for what should be the same thing, as a result of one piece of data having a few copies and not all of them being updated. So if someone's address is on a system several times, and then their address changes, but it is only updated in some of those places, then the person will have both their old and new address on the system. The data is not consistent then. To avoid this data should be only stored once and everyone that needs it looks at the one set, rather than each having their own copy.
DO you have redundancy of records in distributed DBMS?
Redundancy means duplicacy of data or repetitive data. In distributed database case the data is stored in different systems . So the answers is yes there can be redundancy of records / data.In distributed database , data is stored in different systems. Since the data is distributed there is redundancy of records.
What are three types of redundancy checks used in data communications?
coding redundancy interpixel redundancy psycovisual redundancy
What is the full form of GRS?
GRS stands for "Global Redundant Server". It refers to a system of servers that are geographically distributed to provide redundancy in case of system failures or disasters.
What is it called when you have a system then a system in case the first system fails?
I was looking for the answer to that myself, then I recalled something about redundancy, I think maybe dual redundancy, or something along that line.
What is the difference between controlled redundancy and uncontrolled redundancy?
Controlled redundancy refers to intentionally duplicating certain components in a system to ensure reliability and fault tolerance, whereas uncontrolled redundancy occurs unintentionally due to inefficient processes or lack of coordination. Controlled redundancy is planned and managed to enhance system performance, while uncontrolled redundancy can lead to inefficiencies and waste of resources.
What is oxymoronic redundancy?
Oxymoronic Redundancy: A redundant statement used to confuse Tiffany Hyde.
What is redundancy-?
Redundancy is the excessive repetition of something. A common example used by teachers/comic strip writers is the "Redundant Department of Redundancy" In the field of computers or electronics redundancy refers to having multiple components with the same function so that one or more can fail and the entire system can continue to function.
A software package generally used with in a distributed word processing system is?
DWPs
What is the difference between redundancy and duplication?
Redundancy refers to the inclusion of extra components to ensure system reliability, while duplication involves creating an exact copy of something. Redundancy can help prevent system failure by providing backup options, while duplication involves replicating data or information for various purposes.
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.
What is an example of fail safe principle of redundancy?
There is a school of thought residing with how much redundancy should be built in. obviously more redundancy should make it more reliable however those same additional parts could make the system fail as a consequence of additional redundancy.
Is computer network and distributed system is similar?
distributed system is a special case of computer network.ofcourse distributed system is a network but a network may or may not be distributed.In general,a computer network is a very general term but distributed system is more specific..
