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).
The Input and Output Devices are simply our screen, keyboard, mouse, microphone, speaker, touchpad, etc. They are all of the ways we interact with the computer.
These days, most computers also have a Network Connection to retrieve information over a network. We can think of the network as a very slow place to store and retrieve data that might not always be “up”. So in a sense, the network is a slower and at times unreliable form of Secondary Memory.
While most of the detail of how these components work is best left to computer builders, it helps to have some terminology so we can talk about these different parts as we write our programs.
As a programmer, your job is to use and orchestrate each of these resources to solve the problem that you need to solve and analyze the data you get from the solution. As a programmer you will mostly be “talking” to the CPU and telling it what to do next. Sometimes you will tell the CPU to use the main memory, secondary memory, network, or the input/output devices.

Explanation:
A programming language is a type of written language that tells computers what to do. Programming languages are used to write all computer software. A programming language is like a set of instructions that the computer follows to do something.
Examples are: python, ruby, jupiter ,java, JavaScript, C, C++, and C#.
