### Types of Signals

Signals are delivered as a result of some event. UNIX signals are grouped into the following four categories of pairs that are orthogonal to each other:

· Terminating and synchronous

· Terminating and asynchronous

· Nonterminating and synchronous

· Nonterminating and asynchronous

The action that DCE Threads takes when a particular signal is delivered depends on the characteristics of that signal.
