Understanding how a computer works after you press the power button is key to working with technology effectively. On this course, you will explore what happens inside the machine and learn how computers turn inputs into outputs. You will learn what the computer operating system does and why you need it. You will also compare software and hardware, understand the importance of the central processing unit (CPU), and address factors that affect computer performance.
Understanding Computer Systems – Period 1
We live in a society exquisitely dependent on science and technology,in which hardly anyone knows anything about science and technology.Carl Sagan (American astronomer, cosmologist, astrophysicist, astrobiologist, and author)
