ذاكرة الكمبيوتر Computer Memory

ما هى ذاكره الحاسوب What are the computer memory ؟
ذاكرة الكمبيوترهى المكان الذي يتم تخزين البيانات و المعلومات به حيث يوجد نوعان رأسيتان من الذاكرة داخل الكمبيوتر و هي :
Computer memory is the place where we can store data and information, where there are two types of memory in the computer.


 RAM (Random Access Memory)

ذاكرة الوصول العشوائى : حيث يتم تحميل نظام التشغيل و البرامج الأخرى مثل Word و Excel و غيرها
Random Access Memory is where we can upload the operating system and the application programs such as MS Word, MS Excel and others.

ROM (Read Only Memory)

 ذاكرة القراءه فقط : هىشريحة تحتوي على بيانات المصانع التي قامت بتصنيع أجزاء الكمبيوتر و الساعة و البرامج التي تسمح لنظام التشغيل بالتحميل على الذاكرة RAM
Read Only Memory contains the manufacture data and some other data such as the 
clock.
 ما الفرق بين RAM و ROM  ؟
RAM
ROM
Random Access Memory
Read Only Memory
ذاكرة مؤقتة  Changing, temporary
ذاكرة دائمة Permanent, Unchanging
تحتوي على نظام التشغيل و البرامج بمجرد فتح الجهاز و تحميل البرامج Loading
تحتوي على معلومات نظام التشغيل و الأجزاء الصلبة
المحتوى يختفي بمجرد غلق الجهاز Disappear
المحتوى لا يختفي بمجرد غلق الجهاز Don't disappear

وحدات قياس ذاكرة الحاسوب

 Computer Measurements


ما هى وحدات قياس ذاكره الحاسوب ؟
 What are the measurement units of the computer memory ?
هناك العديد من وحدات قياس الذاكرة و هي كما يلي مرتبة من الصغير الى الكبير
There are some measurement units we use to measure the computer memory. These units are (from the smallest to the biggest)
Bit هي وحدة القياس الأساسية
Byte = 8 Bit
Kilobyte = 1000(1024) Byte
Megabyte= 1000(1024) Kilobyte
Gigabyte = 1000(1024) Megabyte

 قياس أداء الحاسوب Computer Performance


كيفيه قياس أداء الحاسوب؟
 How to measure the computer performance?
هناك عدة عوامل يمكن أستخدامها في قياس أداء الحاسوب Computer Performance وهي:
-         سرعة المعالج CPU Speed
-         حجم الذاكرة المؤقتة RAM Size
-         سرعة و حجم القرص الصلب Hard disk Speed and Space
-         عدد البرامج المفتوحة في نفس الوقت Number of opening applications
There are some factors we can use to measure the computer performance . These factors are:
CPU Speed
RAM Size
 Hard disk Speed and Space
 Number of opening applications
