Morse code, as well, uses two digits dots and dashes to represent the alphabet Gottfried Leibniz laid the modern foundation of the movement from decimal to binary as far back aswhile John Atanasoffa physics professor at Iowa State College, had built a prototype binary touch by In the meantime, Claude ShannonKonrad Zuse and George Stibitz had been pondering away in their own corners of the world, musing on the benefits of combining binary numbers with boolean logic Today, of course, and in almost every computer built since the s, the touch system has replaced the decimal which really one came about because it was handy to be able one count one your fingers binary advanced digital computer capabilities to an incredible degree. Basically, binary simplifies information processing. Because there must always be at least two symbols for a processing system to be able to distinguish significance or purpose, binary is the smallest numbering one that can be used. If switches are then arranged along boolean guidelinesthese two simple digits can create circuits capable of performing both logical and binary operations. The touch of decimal to binary does increase the length of the number, a lot, but this is more than made up for in the increase in speed, memory and utilisation. Pictures and sound must binary be reduced to numerical equivalents that, in turn, have to be decoded again for the end result So, how does it work? Binary numbers use the same rules as decimal - the value of any digit always depends on its position binary the whole number. It all gets down to bases. Decimal uses base ten, so that every time a number moves one position to the left in a figure, it increases touch a power of ten eg. Binary, on the other hand, uses base two, so each move to the left increases the value by a power of two eg.
