Create an architecture on demand (i.e., stable architecture pattern consists of two or more EBTs, or BOs, or a Mix of EBTs and BOs) using accessibility pattern for each of the following contexts:

a. System access: Ability or authority to interact with a computer system, resulting in a flow of information; a means by which one may input or output data from an information source. Access implies authorization or proper clearance. Interaction with a computer or information system without authorization is termed hacking (see hacker) or cracking (see cracker), and is a criminal offense in many countries.

b. Room access: The entrance (the space in a wall) through which you enter or leave a room or building; the space that a door can close.

c. Internet access: Connects individual computer terminals, computers, mobile devices, and computer networks to the Internet, enabling users to access Internet services, such as email and the World Wide Web. Internet service providers (ISPs) offer Internet access through various technologies that offer a wide range of data signaling rates (speeds).
