101Metro Ethernet — A Metro Ethernet is a computer network that covers a metropolitan area and that is based on the Ethernet standard. It is commonly used as a metropolitan access network to connect subscribers and businesses to a larger service network or the… …
102Buck converter — A buck converter is a step down DC to DC converter. Its design is similar to the step up boost converter, and like the boost converter it is a switched mode power supply that uses two switches (a transistor and a diode) and an inductor and a… …
103Toronto space — In mathematics, in the realm of topology, a Toronto space is a topological space that is homeomorphic to every proper subspace of the same cardinality.There are five homeomorphism classes of countable Toronto spaces, namely: the discrete topology …
104List of algebraic structures — In universal algebra, a branch of pure mathematics, an algebraic structure is a variety or quasivariety. Abstract algebra is primarily the study of algebraic structures and their properties. Some axiomatic formal systems that are neither… …
105Valve audio amplifier - technical — Circuitry and performance Characteristics of valves Valves are very high input impedance (near infinite in most circuits) and high output impedance devices. They are also high voltage / low current devices.While valves themselves are described… …
106Distributed firewall — A firewall is system or group of system (router, proxy, or gateway) that implements a set of security rules to enforce access control between two networks to protect inside network from outside network. It may be a hardware device or a software… …
107Mereology — In philosophy and mathematical logic, mereology (from the Greek μέρος, root: μερε(σ) , part and the suffix logy study, discussion, science ) treats parts and the wholes they form. Whereas set theory is founded on the membership relation between a …
108Fuchsian group — In mathematics, a Fuchsian group is a particular type of group of isometries of the hyperbolic plane. A Fuchsian group is always a discrete group contained in the semisimple Lie group PSL(2,C). The name is given in honour of Immanuel Lazarus… …
109Cone (linear algebra) — In linear algebra, a (linear) cone is a subset of a vector space that is closed under multiplication by positive scalars. In other words, a subset C of a real vector space V is a cone if and only if λx belongs to C for any x in C and any positive …
