'''Open architecture''' is a type of [[computer architecture]] or [[software architecture]] intended to make adding, upgrading, and swapping components with other computers easy.<ref name="II2011">{{cite book|author=Clifton A.

That decision led to the market for add-in boards, for large numbers of third party applications, and eventually to a large number of competitors all creating "IBM-compatible" machines. [[William C.

It had two expansion slots, one on the side and one on the bottom.''"

Open architecture systems may use a standardized [[system bus]] such as [[S-100 bus|S-100]], [[Peripheral Component Interconnect|PCI]] or [[Industry Standard Architecture|ISA]] or they may incorporate a proprietary bus standard such as that used on the [[Apple II]], with up to a dozen slots that allow multiple hardware manufacturers to produce add-ons, and for the user to freely install them. By contrast, closed architectures, if they are expandable at all, have one or two "expansion ports" using a proprietary connector design that may require a license fee from the manufacturer, or enhancements may only be installable by technicians with specialized tools or training.

[[Computer platform]]s may include systems with both open and closed architectures. The [[Mac mini]] and [[Compact Macintosh]] are closed; the [[Macintosh II]] and [[Power MacintoshMac G5]] are open. Most [[Desktop computer|desktop PCPCs]]s are open architecture, but [[nettop]]s are typically closed.

Similarly, an open software architecture is one in which additional software modules can be added to the basic framework provided by the architecture. Open APIs (Application Programming Interfaces) to major software products are the way in which the basic functionality of such products can be modified or extended. The [[Google APIs]] are examples. A second type of open software architecture consists of the messages that can flow between computer systems. These messages have a standard structure that can be modified or extended per agreements between the computer systems. An example is IBM's [[Distributed Data Management Architecture]].

Open architecture allows potential users to see inside all or parts of the architecture without any proprietary constraints.<ref>{{cite book|url=https://books.google.com/books?id=Zk2qCAAAQBAJ&pg=PP6 |title=TRON Project 1987 Open-Architecture Computer Systems: Proceedings of the Third TRON Project Symposium|isbn=9784431680697|last1=Sakamura|first1=Ken|date=6 December 2012|publisher=Springer }}</ref> Typically, an open architecture publishes all or parts of its architecture that the developer or integrator wants to share. The [[open business]] processes involved with an open architecture may require some license agreements between entities sharing the architecture information. Open architectures have been successfully implemented in many diverse fields, including the [[USUnited States Navy|U.S. Navy]].<ref>{{cite web|url=http://www.navy.mil/navydata/cno/n87/usw/spring08/HowAndWhy.html|title=The HOW and WHY of OPEN ARCHITECTURE|work=[[navy.mil]]|access-date=2015-07-02|archive-url=https://web.archive.org/web/20150705034123/http://www.navy.mil/navydata/cno/n87/usw/spring08/HowAndWhy.html|archive-date=2015-07-05|url-status=dead}}</ref>

On 24th of June 2021, Microsoft has introduced Windows 11. Amongst other hardware requirements it has TPM 2.0 requirement. This potentially could allow Microsoft to track every computer Windows 11 is installed on, have Microsoft more monopoly where it has been for decades (Software market) and continue to promote Close-Architecture (move towards similar platforms Apple offers) to devices such as Laptops, Tablets, Smart Phones. Microsoft is in close communication with hardware developers of an Open Architecture Platforms to meet the Software Developer criteria.

Such software requirement for the hardware is controversial in the sense of data protection and personal data sensitivity. Windows has very well established Multilanguage platform distributed along the Globe as well as supporting and supplying Governments and countries with its products.
