III GLOSSARY:
BUS
A conductor used for transferring data, signals or power.
COMPUTER
A machine that inputs data, processes data, stores data, and outputs data. DATA
Representation of information in a coded manner suitable for communication, interpretation, or processing.
ADDRESS DATA
Data that represent or identify a source or destination.
INSTRUCTION DATA
Data that represent an operation and identify its operands, if any.
STATUS DATA
Data that represent conditions of data, digital data processing systems, computers, peripherals, memory, etc.
USER DATA
Data other than address data, instruction data, or status data.
DATA PROCESSING
See PROCESSING, below. DIGITAL DATA PROCESSING SYSTEM
An arrangement of processor(s) in combination with either memory or peripherals, or both, performing data processing.
ERROR
Manifestation of a fault as an undesired event that occurs when actual behavior deviates from the behavior that is
required by initial specification. This includes a change in information content of pulse or pulse coded data to a state or value other than the normal state or value of a properly operating device or system.
FAULT
A flaw in a functional unit (hardware or software).
INFORMATION
Meaning that a human being assigns to data by means of the conventions applied to that data.
MEMORY
A functional unit to which data can be stored and from which data can be retrieved.
PERIPHERAL A functional unit that transmits data to or receives data from a computer to which it is coupled.
PROCESSING
Methods or apparatus performing systematic operations upon data or information exemplified by functions such as data or information transferring, merging, sorting, and computing (i.e., arithmetic operations or logical operations).
(1) Note. In this class, the glossary term data is used to modify processing in the term data processing; whereas the term digital data processing system refers to a machine performing data processing.
PROCESSOR
A functional unit that interprets and executes instruction data.
RECOVERY
Responding to a fault in a system by either returning a system to a previous level of correct operation, achieving a degraded level of correct operation, or safely shutting down the system.
SECURITY
Extent of protection for system hardware, software, or data from maliciously caused destruction, unauthorized modification, or unauthorized disclosure.
