Binary number numerals. For example, the binary numeral 100 is pronounced "one zero zero", rather than "one hundred", to make its binary nature explicit, and for purposes of correctness. Since the binary numeral 100 represents the value four, it would be confusing to refer to the numeral as "one hundred" (a word that represents a completely different value, or amount). Alternatively, the binary numeral 100 can be read out as "four" (the correct "value"), but this does not make its binary nature explicit. Counting in binary is similar to counting in any other number system. Beginning with a single digit, counting proceeds
Universal binary means to ease the transition from the existing PowerPC architecture to systems based on Intel processors, which began shipping in 2006. Universal binaries typically include both PowerPC and x86 versions of a compiled application. The operating system detects a universal binary by its header, and executes the appropriate section for the architecture in use. This allows the application to run natively on any supported architecture, with no negative performance impact beyond an increase in the storage space taken up by the larger binary. Starting with Mac OS X Snow Leopard, only Intel-based Macs are supported, so software that specifically depends
