3. DEFINITIONS

4. Ampere
the basic unit of electric current adopted under the Systeme International d'Unites
Analog circuit
Reciprocal of Digital Circuit (see below)
Atom
(physics and chemistry) the smallest component of an element having the chemical properties of the element
Binary
consisting of two (units or components or elements or terms) or based on two
Bit
a unit of measurement of information (from Binary + digIT)
Byte
A byte is another word for character; generally represented by 8 bits.
Circuit
an electrical device that provides a path for electrical current to flow
Current
a flow of electricity through a conductor
Digital circuit
A unit that acts as a series of digital switches, or memory, which retain the necessary sequence of digital bits required for various program data.
Diode
a semiconductor that consists of a p-n junction
Electron
an elementary particle with negative charge

5. Integrated circuit
a microelectronic computer circuit incorporated into a chip or semiconductor
Neutron
an elementary particle with 0 charge and mass about equal to a proton
Ohm
a unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere
Ohm's Law
V=IR
Proton
a stable particle with positive charge equal to the negative charge of an electron
Resistance
an electrical device that resists the flow of electrical current
Resistor
a device that slows the flow of current
Semiconductor
a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator
Short circuit
a connection that allows current to take an unintended path
Thermistor
a semiconductor device made of materials whose resistance varies as a function of temperature
Transistor
a semiconductor device capable of amplification
Volt
a unit of potential equal to the potential difference between two points on a conductor carrying a current of 1 ampere when the power dissipated between the two points is 1 watt
