			====security====

			[http://en.wikipedia.org/wiki/Operating_system#Security resource]

			The operating system must be capable of distinguishing between requests which should be allowed to be processed, and others which should not be processed. Authentication is used to identify who is making a given request.


			====IO====
			For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it.

	~~C++ comes packaged with libraries.~~
	*some examples are cmath, cstdio, and random
	*often cmath and math.h are synonyms for each other
	**this is a quirk that's leftover from original C

	Motherboard specifically refers to a printed circuit board (PCB) with expansion capability. As the name suggests this board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives, TV tuner cards, extra USB ports, firewire ports, or other forms of persistent storage.

	The value of fully meshed networks is proportional to the exponent of the number of subscribers, assuming that communicating groups of any two endpoints, up to and including all the endpoints, is approximated by Reed's Law.

	====Ring====		====Ring====
			[http://en.wikipedia.org/wiki/Network_topology#Ring resource]

	A network topology that is set up in a circular fashion in which data travels around the ring in one direction and each device on the ring acts as a repeater to keep the signal strong as it travels. Each device incorporates a receiver for the incoming signal and a transmitter to send the data on to the next device in the ring. The network is dependent on the ability of the signal to travel around the ring. When a device sends data, it must travel through each device on the ring until it reaches its destination. Every node is a critical link.[4] In a ring topology, there is no server computer present; all nodes work as a server and repeat the signal. The disadvantage of this topology is that if one node stops working, the entire network is affected or stops working.
