When someone says that they have windows it is widely accepted that anything will run on this operating system if it is Windows compatible. This allows anyone to use the consumer to use the Windows system with confidence and versatility. For corporations this idea of a standard is very important. It allows them to concentrate on creating one type of software programming medium that will work on any Windows based computer. One example of a negative impact when you do not have standards is chaos. One example where there is chaos is the cellular phone industry. When this industry began it used about four different standards. Each different company uses a different standard in the operations of their phones. This transfer technology, whether GSM or analog, creates many problems. There is no versatility between most cellular phone networks. Each company has built their own networks and has kept the technology advancements stagnant because of the lack of standards. Microsoft has played a huge part in the advancement of computer technology and the internet because of their ability to create industry-wide standards. Along with other technology companies like Intel, and other PC manufacturers in the computer technology, there has been an advancement that has been unparalleled since Rockefeller's oil empire of the early 20th century. Computers have not only changed the way we work, but our business practices and the way we communicate. Even Michael Dell, founder of the direct selling of PCs to consumer, praises Microsoft and its success. He says, "Microsoft's biggest impact has been the advocation of a broad standard for personal computing that has been massively accepted and dominates the PC industry around the world. As part of that, they have facilitated applications, which is a self-reinforcing concept. This is a company that has spent a tremendous amount of time assuring that its platform is widely utilized and accepted.
