Goliath

Goliath is described in the biblical Book of Samuel as a tall Philistine warrior who was defeated by young David in single combat. Post-Classical Jewish traditions stressed his status as the representative of paganism, in contrast to David, the champion of the God of Israel. Christian tradition sees in David's overcoming Goliath the victory of God's king over the enemies of God's helpless people and interprets this as prefiguring Jesus' victory over sin and the Church's victory over Satan. The phrase "David and Goliath" (or "David versus Goliath") has taken on a more popular meaning, denoting an underdog situation, a contest where a smaller, weaker opponent faces a much bigger, stronger adversary. "used to describe a situation in which a small or weak person or organization tries to defeat another much larger or stronger opponent: The game looks like it will be a David and Goliath contest.".

MOSFET

MOSFET showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (white). surface-mount packages. Operating as switches, each of these components can sustain a blocking voltage of 120nbspvolts in the ''off'' state, and can conduct a continuous current of 30 amperes in the ''on'' state, dissipating up to about 100 watts and controlling a load of over 2000 watts. A matchstick is pictured for scale. A cross-section through an nMOSFET when the gate voltage ''V''GS is below the threshold for making a conductive channel; there is little or no conduction between the terminals drain and source; the switch is off. When the gate is more positive, it attracts electrons, inducing an ''n''-type conductive channel in the substrate below the oxide, which allows electrons to flow between the ''n''-doped terminals; the switch is on. Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. Note that the threshold voltage for this device lies around 0.45 V The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon.
