faulttoleranttietojenkäsittelyä
Fault-tolerant computing, or faulttoleranttietojenkäsittelyä in Finnish, refers to the design of computer systems that can continue operating, at least at a reduced level, rather than failing completely when some part of the system fails. The goal is to ensure availability and reliability even in the presence of hardware or software errors. This is particularly crucial for critical applications where downtime can have severe consequences, such as in financial systems, power grids, and aerospace.
Several techniques are employed to achieve fault tolerance. Redundancy is a key principle, where multiple components
Recovery mechanisms are also vital. If an error cannot be prevented or corrected, the system must be
