    You need to learn to use one of the many programming languages. It take much time and effort. It is probably best to take a course to get you started. Good programmers can easily earn 40 to 100K.

    If your computer was around 50 to 60 years old, you would have to use a "Front Panel" in order to program it with 1's and 0's. A Front Panel was just a box with switchs on it. It had 16 switchs on one side to access the memory address. And it had 8 switchs on the other side for the data. And it had 1 switch on the bottom right which was the input or enter switch. Today, all computers are pre-programmed with a EPROM chip known as the BIOS chip. EPROM means Erasable Programmable Read Only Memory and BIOS means Basic Input/Output System. The BIOS is the brain of the computer. A lot of stupid people believe that the brain of the computer is the operatiing system but it's not. How the system works is, the BIOS talks to everything inside the computer, it even talks to the Operating System. When you plug something into the USB port or whatever the BIOS informs the Operatiing System about it. When you press a key on the keyboard, the BIOS tells the Operating System that a certain key was pressed and then the keyboard character is displayed through the Operatiing System. Do you get it? Or did I lose you?
