Central Processing Unit and Software Compatibility

The computer processor inside a PC or PC-clone computer has totally different architecture (microscopic "wiring" schematic) inside the central processing unit chip (the CPU, or "chip"). In other words, the specific way the circuits are laid out in a computer chip (CPU, central processing unit) is called the chip architecture. PC chips and Mac chips have processing units with totally different architecture. Software is not interchangeable. Buy Mac software for the Macintosh and buy PC software for PC computers. An Apple or Mac computer is not a PC. Most PC Computers are sold new with a Windows operating system but keep in mind that other operating systems can also run on PC-architecture machines. One example of another operating system that can run on a PC machine is Linux for Windows. When two operating systems are on a disk they are installed on separate "partitions" of the disk. That is similar to two songs on one CD having to be on separate "tracks"
