Hex is used in mathematics and information technologies as a more friendly way to represent binary numbers. The letters are used because of the need to represent the values 10, 11, 12, 13, 14 and 15 each in one single symbol. These are the 10 decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and the first six letters of the English alphabet (A, B, C, D, E, F). As a base-16 numeral system, it uses 16 symbols. So if you can't read binary code, then cut and paste it, put it into the translator and get the binary translation.The hexadecimal system (shortly hex), uses the number 16 as its base (radix). The reason for this, for the real geeks out there, is that the maximum value of any character using the ASCII system (included the extended ASCII codes)is 255 which conveniently in binary is:Ġ1101001 00100000 01101100 01101111 01110110 01100101 00100000 01111001 01101111 01110101Īnd if you really need to shout it is. The binary translator on this page ensures that each binary 'number' is eight digits long giving us (for 123):. Using our example of '123' the meaning of which is obvious in decimal, but (without the spaces) would be 11011 in binary which would be 27 in decimal. There is one final step necessary, and that is we need to ensure that all the binary numbers have the same length otherwise when translating the binary back into characters or numbers confusion would arise. For simplicity, we'll convert '123' into binary, but exactly the same principle is used to translate ascii or unicode text into binary.Ġ, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010Ĥ8, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60Įssentially all that has to be done is to match the ascii number to the corresponding binary value. ![]() Surfacelanguages' in binary is 128 characters long and 'Hello world' has a length of 80 characters, which goes some way to explaining why humans don't use it very often.Īnd if you have made it this far, here is a rather more detailed explanation of how to translate text into binary. There is a more modern system known as UNICODE which allows a greater range of characters to be displayed, but is is not used in this binary to text translator. There is more than one format.ĪSCII (American Standard Code for Information Interchange) is the most common format for text files. Firstly, the letters need to be converted into numbers, and secondly the numbers need to be converted into binary.Įvery alphabetic, numeric, and character that can be displayed on a computer screen has a corresponding is represented with a number defined by a universally known and understood format. There are two stages to a binary translator. We count using decimal, and because we all know how to do this, don't really think about how it works, or why for example there are nine numbers, and not say sixteen, eight or perhaps two. ![]() So, these switches, can either be on or off, which equate to the digits one and zero, and can be used to count. Technology whether it be powered by values, or integrated cirucits is used to create logic gates, which are binary systems. There have been further shifts with integrated circuits and surface mounted technology but fundamentally deep down at the level of logic, nothing has changed. Technology moved on and valves were replaced by transistors. ![]() Many years ago (starting with the Manchester Mark 4), these logic gates were composed of valves. On and off, giving us the binary states of one and zero. Logic gates only have two possible states and can these can either be on or off. In order to understand how binary translation works, or how letters are converted into a series of ones and zeros (binary or base two), a quick introduction to how computers function is useful.Īll digital computers (analog computers also exist), from the most powerful mainframe to the smallest personal computer, as well as all phones, calculators and digital devices which perform any form of calculation, at their heart work using logic gates.
