PC Open Architecture PC Open ArchitectureThe idea of open architecture is one of the main reasons why all PC compatibles have become so popular. The PC may be upgraded in any way possible even by by individuals who have no extensive experience. One of the great advantages is the ability we have to add or take out various components as we please thus bringing out our PC's full potential.
All this was made possible when IBM, in the early 80's, created the first Personal Computer; and with it the concept of Open Architecture. This meant that only a few necessary parts were installed in a steel box so that it could function as a computer. From then on, each user could add components in order to enhance the machine's performance.
Yet the greatest advantage in the open architecture concept is that there are certain rules that all components and all manufacturers must follow. Screws, plugs, power supplies, dimensions even communications protocols have been predefined in every detail.
As time went by the standard components of the first PCs were enhanced so as to meet the continuously increasing potential of new CPUs, peripherals and software. Often new components were developed but backwards compatibility was always a must. This means that a software program or some piece of hardware made today may not work on a PC made a few years back, but a software program or a piece of hardware made for the original PC will function properly on a PC made today.
