ان جهاز الحاسب يعتمد على القرص الصلب بشكل رئيسي لان جميع المعلومات تتخزن فيه، بالاضافة نظام التشغيل
هناك عدة عوامل تؤثر على القرص الصلب ، منها
- معدل نقل البيانات Data rate هو عدد الـ Bytes التي يتم نقلها من القرص الصلب للكمبيوتر في الثانية الواحدة, ويتراوح بين 5 إلى 40 ميجابايت في الثانية الواحدة وهي في ازدياد مع التقدم التقني.
- زمن الوصول Seek Time هو الزمن المستغرق بين طلب الملف من القرص الصلب ووصول أول Byte من الملف إلى الكمبيوتر.
- سرعة دوران القرص الصلب، فكلما كانت سرعة الدوران أعلي كان ذلك أفضل.
- نوع ال Interface الذي يستخدمه القرص الصلب.
- الكثافة التخزينية، وهي عدد ال Bytes التي يمكن تخزينها في مساحة معينة من القرص الصلب.
- وطبعا الأهم من ذلك السعة capacity الكلية للقرص الصلب مثلا 20، 40، 80، 120، 160، 250, 320 , 500 جيجابايت..
الملخص
انه كل ما زادت سرعة نقل البانات وزادات المساحة فان ذلك يعمل على زيادة سرعة اداءالجهاز

What is the probability of after six girls born the next child being a girl?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes. Unfortunately there is no readily available research into the genders of seven or more children to establish the experimental probability for such an outcome. However, if you assume that they are independent events then, given that the probability of a girl is approx 0.48, then the probability of the seventh child being a girl is 0.48.
