يتحدث الدرس عن المخاطر التى تهدد امن البيانات و المعلومات الفرق بين البيانات و المعلومات : البيانات هو شئ ليس له معنى مثل رقم 26 او اسم محمد او عنوان شارع السلام اما المعلومات فهى عبارة عن البيانات بعد معالجتها من خلال الكمبوتير مثال : محمد عبد الرحمن سنه 26 سنة و يسكن فى شارع السلام .. فهنا تم تحويل البيانات إلى معلومة مفيدة بعد معالجتها و إذا لاحظت انك عندما يطلب منك فى مكان ما ان تملئ فورم معينه ، فإنه يطلب منك ان تملئ بياناتك و ليس معلوماتك فإستخدام الكمبيوتر تبدأ بعملية ادخال البيانات للكمبيوتر حتى يقوم بمعالجتها لإستخراج المعلومات

When the angular velocity changes during a particular time, we say that the body has angular acceleration which depends on such change in the angular velocity. The average angular acceleration using the initial angular velocity and the final angular velocities :

We have studied the linear motion under the influence of a constant acceleration and found the necessary laws for that, but now we know we have the angular velocity and angular acceleration

Let us study a body of mass m and that the body consists of steel particles with different dimensions and its distribution is constant in the material. This object moves around a fixed axis at the point 0 with constant angular velocity
