Open architecture is an architecture that allows assembly, improvement and repair of a computer by its constituent elements – modules. The principle of open architecture is used in the design of personal computers, in the production of IBM-compatible (or Intel-compatible) PCs. An open specification for the architecture of a computer or peripheral device allows third-party manufacturers to develop complementary devices to open architecture systems.
The main feature is simplicity, the ability to easily change the configuration of the computer by adding new or replacing old devices.
