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؟

زيادة التعقيد في التطبيق.

الحاجة للأدوات الإضافية لعمل التحديث.

القليل من استهلاك الموارد.

سرعة التحديث المضاعفة. (correct)
