Binary code is the perfect place to start ... are they translated into a binary data format that the computer can read and execute. Programming languages like this are called "high-level ...

In the case of a computer, that binary code might be stored in high and low voltages ... and for some purposes – usually large ones – it is easier to program than a machine that handles only 16 bits ...

To a programmer, code can seem a “domain of sorcery” in which strings of characters have power in the real world.

so that code is compiled by a program called, not surprisingly, a compiler. The compiler converts high-level commands into binary digits. The computer will then execute the resulting program ...

Ever since the invention of the computer ... binary state of affairs may be about to change. Yet how will mere mortal coders manage to take advantage of all that potential speed, when programming ...

Binary code is also the system that powers computers ... If you want to use data in a computer program, you feed that data to a thing in the program called a variable. Variables also have types ...
