Glossary of Terms

application	A piece of software (a program) consisting of one or more
	processes and supporting functions.
ASCII	American Standard Code for Information Interchange. A seven-
	bit code that standardizes a set of characters representing letters
	and numbers for international use.
Baud rate	A measurement of the speed of a communications line; the
	number of times a line can change state in one second; the rate at
	which a signal is modulated.
Binary	A number system having only two symbols (1 and 0), and where
	values are expressed in the base two number system.
Bit	Abbreviation of binary digit. The smallest unit of information in a
	binary system. Has a value of either one (1) or zero (0).
Bits per second	The speed at which a channel transmits (in a serial transmission) a
	single bit. A serial transmission sends one bit at a time.
	Abbreviated as bps.
Byte	A group of eight adjacent bits that function as a single unit.
	Defined as an octet by the International Electrotechnical
	Commission (IEC).
Change of state	A significant change (as defined by a particular system) in the
	condition of a point being monitored, for example, a change in
	flow rate, temperature, voltage, etc. Usually associated with dual-
	state status (that is, alarm/normal conditions). Abbreviated as
	COS.
Char	The name of a data-type in the C programming language. Stands
	for character, or a group of eight bits that function as a single unit.
Configuration	The data or information that defines the operational limits and
information	characteristics of a particular device. Depending on the device,
	this information is either manually downloaded into NVRAM or
	EEPROM, or is pre-programmed into EPROM.
Configuration	See WESDAC Configuration System.
