"Dependability via Redundancy" in computer architecture refers to the concept of having backup components or systems in place to ensure the overall reliability and availability of the system. This can include having multiple copies of data, duplicate hardware, or even redundant software processes.

The steps to understand this concept are as follows:

1. Redundancy: This is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe.

2. Dependability: This is a measure of a system's reliability, availability, and its ability to operate continuously without failure. It's a key attribute in computer systems used for critical operations.

3. Dependability via Redundancy: This is the concept of improving a system's dependability by implementing redundancy. If one component fails, the system can switch to a redundant component, thereby maintaining operation.

Redundancy is important in system design for several reasons:

1. Improved Reliability: Redundancy can significantly improve the reliability of a system. If one component fails, a backup is available to take over, reducing the chances of system failure.

2. Increased Availability: Redundancy can increase the availability of a system. In a redundant system, maintenance and upgrades can be performed on one component while the other continues to operate, minimizing downtime.

3. Data Protection: Redundancy is crucial for protecting data. By storing data in more than one place, the risk of data loss is reduced.

4. Fault Tolerance: Redundancy provides fault tolerance, the ability for a system to continue operating even if a component fails. This is particularly important in systems where continuous operation is critical.

In conclusion, "Dependability via Redundancy" is a key principle in computer architecture and system design, aimed at ensuring that systems are reliable, available, and able to tolerate faults.
