Introduction to Computer Architecture

First of all I want to thank you for this free course and for helping me to promote my self by education. My name is Bereketeab Fikremariam and I'm from The state of Eritrea, east Africa. I have been wanting to learn Architecture for long but since I'm not able to pay it I couldn't. When a friend of mine told me about this I immediately searched and here I am. I have B.C degree in applied physics and I look forward for the course.
