Questions and Answers

ما هو الفرق الرئيسي بين إنشاء عملية وإنشاء خيط في تطبيق متعدد الرتب؟

  • إنشاء العملية يتطلب موارد أقل من إنشاء الخيط.
  • إنشاء العملية أبطأ من إنشاء الخيط. (correct)
  • إنشاء الخيط يتطلب تجزئة الموارد بشكل أكبر من إنشاء العملية.
  • إنشاء الخيط أسهل من إنشاء العملية.

    • لماذا يُفضل استخدام خيوط متعددة في التطبيقات الحديثة؟
