How is fault tolerance applied in road systems?
If one road is blocked, you can still reach your destination using another route.
How is fault tolerance applied to the internet?
The internet is designed to be fault tolerant, ensuring data reaches its destination even if some paths are down.
Give an example of redundancy in data storage.
Having multiple copies of data on different servers or storage devices.
How is fault tolerance used in power generation?
Having backup generators to provide power if the primary power source fails.
How do e-commerce websites use fault tolerance?
Using load balancing to distribute traffic and failover systems to switch to backup servers if the primary ones fail.
How do cloud computing services use fault tolerance?
Replicating data across multiple data centers to ensure availability even if one data center fails.
How does fault tolerance apply to DNS servers?
Using multiple DNS servers to ensure that domain names can be resolved even if one server is down.
How is fault tolerance used in aircraft control systems?
Having redundant sensors and control systems to ensure safe operation even if some components fail.
How do database systems use fault tolerance?
Using replication and backup systems to ensure data integrity and availability even if the primary database server fails.
How is fault tolerance used in network routing?
Routers use multiple paths to ensure data packets can reach their destination even if some links are down.
What is Fault Tolerance?
The ability of a system to continue functioning properly even when one or more of its components fail.
What is Redundancy?
Having extra components that can take over if others fail.
What is Load Balancing?
Distributing traffic across multiple servers to prevent overload.
What is Failover?
Switching to a backup machine if the primary one fails.
What is a DDoS attack?
A cyberattack that overwhelms a server with traffic, disrupting service.
What is the core component of fault-tolerant systems?
Redundancy, which involves having extra components that can take over if others fail.
How do multiple paths contribute to fault tolerance?
Data packets can take different routes if a node or connection fails, ensuring data delivery.
How do multiple internet providers enhance fault tolerance?
Companies can use multiple providers to ensure continuous internet connection even if one provider fails.
What is the role of load balancing in website fault tolerance?
Load balancing distributes traffic across multiple servers to prevent any single server from being overwhelmed.
How does failover contribute to website fault tolerance?
Failover switches to a backup machine if the primary one fails, ensuring continuous service.
What is the impact of increased reliability due to fault tolerance?
Prevents complete system shutdowns due to malfunctions, allowing the system to keep running using other components.
How does fault tolerance reduce cyberattack damage?
Redundant servers can keep a website running during a DDoS attack, mitigating the impact.
How does fault tolerance improve scalability?
More paths for data packets allow more devices to connect to a network, making it easier for a system to expand.
What is a disadvantage of fault tolerance regarding resources?
Requires more materials, construction, and maintenance, increasing resource requirements.
What is a cost-related disadvantage of fault tolerance?
Building and maintaining redundant systems can be expensive.
