Glossary of Terms
Address: A pattern of characters that identifies a unique storage location
Algorithm: A set of procedures to obtain a given result
Ambient: Condition on immediately surrounding atmosphere or area: usually
refers to temperature or pressure
Analog: Refers to circuitry; also called linear circuitry; circuitry that varies certain
properties or electricity continuously and smoothly over a range
Anti-Static Material: A slightly conductive material that allows the net charge to
be drained off through a path; an electrostatic protective material having a surface
resistively greater than 10
4
but not greater than 10
9
Ohms per square inch (does
not generate static electricity)
Binary Number System or Binary Code: A method of writing numbers by using
two digits, 0 and 1
Bit: The smallest possible piece of information; a specification of one of two
possible conditions. (Bits are written as 1 for yes and 0 for no.)
Bus: Large trace or foil extending around the edge of a PCB to provide
conduction for several sources
Byte: A set of adjacent binary digits operated upon as a unit (usually 8 bits)
Charge: The product of capacitance times voltage
CMOS: Complimentary Metal Oxide Substrate semiconductor
Computer: At least one CPU together with input, output, control switch buttons
and memory units
Conductive Material: Material that conducts electrical charge (Because it
conducts charge, there is no potential difference across or storage of a static
charge.); electrostatic protective material having a maximum surface resistivity of
10 Ohms per square unit, or a maximum volume resistivity of 10 Ohms/cm.
Control Buttons: Push buttons on the display bezels to operate the
increase/decrease, advance, or silence functions
Control Switches: Sometimes called dip switches and used for additional
programming features on all levels
