We used to have the numbers 1 to 10 in our decimal system safe and comfortable and, for this system, we can perform basic algebraic operations. Well, there are those who have forgotten to divide by hand and dig into the calculator for digital electronics will kick off the hook.
are also used to have some things to the sexagesimal system. This system, which uses the number 60 as a base, we used to tell time, hours, minutes, seconds-in the measurement of angles ... and even when we buy certain products by the dozen. That, speaking of the dozen, is an old and wise question of domestic practice. Since the dozen is the smallest amount that can be distributed among one, two, three, four or six.
For the binary code is not just another system of counting. What happens is that, as to be had in those early days of digital electronics was zero (no current) and one (yes there is current), were used for these two levels, zero and one, as the basis for counting things. As they did four thousand years before the I Ching.
Any number can be translated into binary code. The three is 11 (one reads one), the ten is 1010 (one zero one zero) or two hundred nine is 11010001. With those numbers in binary coded electronically can do many things. You can make algebraic operations we want and we give the result translated into our comfortable decimal system in the calculator screen, you can store numbers in an electronic storage medium to retrieve it when you want, you can send to any other point in the world via telecommunications networks ... can do everything.
Well, actually it also is translated into binary code just as much as information. The letters of a text, voice, music, photographs, drawings, databases ... everything. If you look at a basic portion, the pixel, for example, and encode by color and quantity of light in a string of zeros and ones that allow us then to replay that pixel on the other hand when we want. The electronics do it for us at full speed, but does so by reading the binary system and painting on the computer screen, pixel by pixel, as it is written in its register of electronic memory.
Although huge amount of zeros and ones that are processed every second, the method used in each "microsecond" by an electronic device is very simple. In fact, based on logic operations developed in the nineteenth century by the mathematician George Boole. From simple operations "AND" to "add" ... and zero zero zero, zero and one equals one ... to more complex but in fact are only operations that always break down the four basic operations of Boolean algebra.
Thus, any instructions we give to a computer in our level of user, for example if you type the letter "p" , translates into an instruction set computer programming at the style binary encoding the p , save it into memory and sends the representation of the letter p a computer screen, each of these indications instructions are broken down into more basic levels of programming, and these in turn into other levels of firmware, use levels, finally, the zeros and ones and Boolean algebra to electronically execute the requested action typing the letter "p" : to be written that letter in the text you are writing and see it in your computer screen.
I hope from now, when we say that this digital electronics and computing that works with binary codes, we sound like Chinese sólo porque ya en el antiguo I Ching se utilizó en los hexagramas la esencia del código de numeración con “ceros y unos”.
