Computer Hardware Architecture
Before we start learning a programming language to give instructions to computers to develop software, we need to learn about how computers are built. If you were to take apart your computer or cell phone and look deep inside, you would find the following parts:
Figure 10: Computer Hardware Architecture
The high-level definitions of these parts are as follows:
The Central Processing Unit (or CPU) is the part of the computer that is built to be obsessed with “what is next?” If your computer is rated at 3.0 Gigahertz, it means that the CPU will ask “What next?” three billion times per second.
The Main Memory is used to store information that the CPU needs in a hurry. The main memory is nearly as fast as the CPU. But the information stored in the main memory vanishes when the computer is turned off.
The Secondary Memory is also used to store information, but it is much slower than the main memory. The advantage of the secondary memory is that it can store information even when there is no power to the computer. Examples of secondary memory are disk drives or flash memory (typically found in USB sticks and portable music players).
