ਸਮਕਾਲੀ ਕਾਰਜਨਿਰਵਾਹ

ਇਸ ਅਧਿਆਇ ਵਿੱਚ ਵਰਣਿਤ ਮੋਡੀਊਲ ਕੋਡ ਦੇ ਸਮਕਾਲੀ ਕਾਰਜਨਿਰਵਾਹ ਲਈ ਸਮਰਥਨ ਪ੍ਰਦਾਨ ਕਰਦੇ ਹਨ। ਉਚਿਤ ਟੂਲ ਦੀ ਚੋਣ ਚਲਾਏ ਜਾਣ ਵਾਲੇ ਕੰਮ (CPU-bound ਜਾਂ IO-bound) ਅਤੇ ਵਿਕਾਸ ਦੀ ਪਸੰਦੀਦਾ ਸ਼ੈਲੀ (ਇਵੈਂਟ-ਚਲਿਤ ਸਹਿਕਾਰੀ ਮਲਟੀਟਾਸਕਿੰਗ ਜਾਂ ਪ੍ਰੀਐਮਪਟਿਵ ਮਲਟੀਟਾਸਕਿੰਗ) 'ਤੇ ਨਿਰਭਰ ਕਰਦੀ ਹੈ। ਹੇਠਾਂ ਇਸਦਾ ਇੱਕ ਸੰਖੇਪ ਜਾਇਜ਼ਾ ਦਿੱਤਾ ਗਿਆ ਹੈ:
