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

but not greater than 10

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
