ALPHANUMERIC
Character set including both letters and numerals and usually other characters. 
(American Standard Code for Information Interchange)
CONTROL CODE
A fixed length machine encoding of a control code name.
CONTROL CODE NAME
The English alphanumeric expression of security classification and any 
need-to-know restrictions for an entity of data or program,
CONTROL MODE
Mode in which a processor can execute the full set of operation codes,
DATA BASE
The store of information records being maintained' for users; includes programs 
as well.
DESCRIPTOR
Instruction for input/output control processor execution,
ELECTRONIC DATA PROCESSING (EDP)
Data processing by equipment predominantly electronic.
ENTITY
A string of bits, characters, or words having an associated control code.
EXECUTIVE CONTROL PROGRAM (ECP)
Program mat controls the secure execution of user programs by assigning hardware 
and performing security related operations.
FAIL SAFE
Program or processing operation terminates automatically whenever proper 
responses to positive checks are not received.
FILE
A related information grouping, e, g, logical records, card images, etc.
FLAG BIT
A bit contained in memory words and used for control purposes rather than actual 
user processing.
FORMATTED FILE SYSTEM
An information storage and retrieval system using a file design having fixed, 
periodic, and variable parts.
INPUT/OUTPUT CONTROL PROCESSOR (IOCP)
A limited purpose processor serving as intermediary between main memory and 
terminal units.
LOGICAL RECORD
A group of related items stored in one or more related physical records, 
depending upon length.
MODE
Processor condition as determined by state of a redundant set of flip-flops.
MULTIPROCESSING
Executing one or more programs simultaneously on more than one processor.
MULTIPROGRAMMING
Executing more than one program, time interleaved.
OBJECT
A contiguous string of instructions, data, or working storage required by a 
program.
ON-LINE
A terminal unit having direct connection with a unit buffer in the input/output 
control processor.
PERIPHERAL UNIT
Any type of input/output equipment connected with a unit buffer in the 
input/output control processor.
PHYSICAL RECORD
The smallest directly addressable portion of the data base.
PRIVILEGED INSTRUCTION
One executable by a processor only in control mode.
PROGRAM REFERENCE TABLE
Contains the name and/or descriptor for each object referenced by a program, and 
the base address and memory bounds for objects in high-speed memory.
SECURITY LEVEL
The maximum security classification authorized for information handled by an 
equipment, as determined by the equipment characteristics or its location.
TERMINAL UNIT
An input or output device in a work station.
THIN-THREAD ANALYSIS
Description of complex system operation or theory by following a single line, 
step-by-step, from start to finish, ignoring the
secondary branches or ideas involved.
USER
Any authorized equipment operator, maintenance person, or intelligence research 
analyst. The system supervisor (or supervisors) is an authorizer as well as user.
USER'S CONTROL PROFILE
Completely describes each user's access authorization for information in the 
system in terms of control code lists by access type (read only or read and 
write). It also includes the user's key pattern information for identification 
plus authentication information for validating that the user really is who the 
user's key pattern indicate.
he is.
USER'S KEY
A physical card or key unique to a user which must be present in the user's key 
pattern generator at a work station to permit information
flow with any terminal unit in that work station.
USER'S KEY PATTERN
An electrical logical bit pattern resulting from the user's key pattern 
generator at a work station which initiates user identification
and is required for information interchange with any terminal unit in that work 
station for that user.
USER'S KEY PATTERN GENERATOR
A transducer from user's key to user's key pattern.
USER MODE
Mode in which a processor can execute only a partial set of operation codes; 
excluded are the privileged instructions.
WORK STATION
A separate, physically secure, area with its own user's key pattern generator in 
which the terminal units can be operated by only one user at a time.
