Binary,...

Computer memory or file content or transport it is just a one-dimensional binary byte array and its corresponding binary address;
The human brain to a computer memory or file contents or transfer the content of the one-dimensional binary byte array and its corresponding binary address some parts as an integer, number of signed/unsigned number, floating point Numbers, complex Numbers, letters, digits, Chinese/Korean/French... Character/string, assembly instructions, functions, function parameters, heap, stack, arrays, Pointers, array pointer and pointer array, the array of arrays, pointer to pointer, two-dimensional arrays, character lattice, the coordinates of character strokes, black and white binary images and grayscale images, color images, audio, video, fingerprint information, id information...

Eventually in binary, decimal and hexadecimal just to show the easy to make you understand, you go to see the code, the last is almost in the form of a byte array

Why cable can transmit binary, good magic, can someone from the electronic level from the microscopic view explain

Is mainly because the wastage of the wire and the limitation of the accuracy of measurement, or more than 2 into the system, why only high level and low level, can have a level in this is ternary, of course, also can have a low level, a third of high level, two-thirds of high level and high level, and so is the quaternary, and so on, make out the decimal information transmission is not completely impossible, electronic engineers lazy just
