Thread-Safe
This is a status descriptor, of the ability to be called upon, for, or by multiple threads, without any risk of conflict or error, and/or interference. It is typically used in and for multi-threaded applications. Numerous threads can access, use, call upon these applications, resources without any at-risk or threats to one, some or any of these processes, functioning or outcome. Simultaneous operations/operational access, shared space, resources, shared address space (control and sequence has to be specified), minimizing surprises, mis-operations and errors. Ways to achieve thread safety would be aspects like: re-entrancy, mutual exclusion, thread-local storage variables, localized so each thread has its own copy and sub-routines, as well as atomic operations.
A measure and method to assist with performance monitoring and optimization, as well as when working with performance counters thread-safe adjusting the value relative to the current value (incrementBy, decrementBy). Code is seen as a thread-safe pertaining to functioning correctly during simultaneous execution by multiple threads.
Thread-safe design and synchronicity enable and implement multi-threaded processes and applications, but problems might cause infinite loops and other difficulties. Use the System.Threading namespace, taking extreme care to be avoiding conflicts and inaccurate calculations for multiple threading.
Key Exam Points
- Use Threading, Thread-Safe processes, programming, implementing and managing mult-threading processes like background-printing, financial application integrity
- Work through the exam study examples for Multi-threaded .NET Framework Applications, practices 1 through 4.
- Take the practice test
