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؟

  • لأنها تجعل عملية التحديث أبطأ.
  • لأنها تجعل البرمجة أكثر تعقيدًا.
  • لأنها تستهلك موارد أكبر من العمليات.
  • لأنها تزيد من كفاءة التطبيق. (correct)

ما هي الميزة الرئيسية لاستخدام خيوط متعددة في تحديث الشاشة؟
