In parallel computing, the threads can talk to each other and exchange information during the computation. In nondeterminism, the only "communication" between threads is that we compute the OR of all possible computation paths. This is much more limited. If you simulate nondeterminism by spawning parallel computations for every nondeterministic choice, you ...

The source of your misunderstanding may be that you think the excerpt contains a list of methods to handle system failures that are mutually exclusive. Masking and tolerating failures often happen simultaneously depending on the interface one part of a system presents to another. Example: a word processor application might only care whether a document was ...

Arbitrary failure means exactly what it says. It means that the failing process should be treated as if an opponent is choosing the process's behavior to try to break your system. Other types of failure, such as omission failures and timing failures, are special cases of this. They are relevant because certain algorithms only guarantee correct results in ...
