FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In the context of web application delivery, fault tolerance relates to the use of load balancing and failover solutions to ensure availability via redundancy and rapid disaster recovery. Load balancing and failover are both integral aspects of fault tolerance.

Detailed explanation-2: -A big contributor to the fault tolerance of the Internet is the redundancy in network routing paths.

Detailed explanation-3: -There are four forms of redundancy that we will study: hardware, software, information, and time. Hardware faults are usually dealt with by using hardware, information, or time redundancy, whereas software faults (bugs) are mostly protected against by software redundancy.

Detailed explanation-4: -The term “redundancy, ” as used in this guide, is the ability to configure one or more backup components (or cards) to take over for a component that fails. Redundancy provides system-wide fault tolerance, helping to ensure that the CSP continues to process calls despite a hardware or software fault.

Detailed explanation-5: -Redundancy: The inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between any two connected devices in a network. Fault Tolerance: Can continue to function even in the event of individual component failures.
