Computers store informaion in bindary code, so, yes, all the characters are stored as binary data. This is the normal practice and the reason why our number system is preferable. Computers recognise two states: on/off, yes/no, true/false. Every character will have a binary value. Given only two possible digits, the resulting code may bemany digits long.
Yes. A computer has the ability to be able to convert ASCII code into binary code. While the ASCII code produces text, a computer converts that information into binary code. What this means is that a computer stores all its data as numbers that are all part of a code. The numbers are the digits of 0 and 1. When it comes to giving the computer an instruction, a string of numbers that are known as a bit string assignment are utilized in order to perform the instruction. Mobile phones are very good example of a computer using binary code.
In the end, ASCII uses letters to produce code. The computer still reads this as binary number code and in turn is able to do the tasks that the ASCII code is wanting to be executed. Binary code is the driving force in being able to make any computer to do what it does. ASCII is converted into binary code by the computer and that is why ASCII is able to do what it does.
