STA

STA

Single-Threaded Apartment. A term used within a Component Object Model technologies (COM), to indicate that each thread operates within its own logical compartment. In STA, COM guarantees that all accesses to thread local storage (TLS) will occur on a single thread. Applications are still allowed multiple threads, but each runs in (logical) isolation and access to global data must be synchronized.

cf Multi-Threaded Apartment (MTA).
