A graph that uses bars to represent the information provided.
bar code
A pattern of bars of various widths and with varying spaces between them, printed on paper or similar material for recognition by a scanner that uses a laser beam or a light source and photocell. Bar codes are used by the U.S. Post Office to encode mail, in stores to price items with the UPC (Universal Product Code), and for many other purposes.
baseline
Where the bottoms of characters in a line of type (excluding descenders) line up. Typesetters measure leading from baseline to baseline.
baseline to baseline
(B/B or b/b) From the bottom of a line of type to the bottom of the next line of type (excluding descenders), used as a measurement of leading.
Basic
Beginner's All-purpose Symbolic Instruction Code. A simple programming language designed in 1963 by John Kemeny and Thomas Kurtz at Dartmouth College. Basic was designed as an easy programming language to learn. Beginners can quickly learn to write simple programs. Originally for mainframes, it is now extensively used on personal computers.
backslash
The character (ASCII 92), not to be confused with the forward slash / (ASCII 47).
BBL
Be Back Later
BCNU
Be seein’ you
beep
A sound emitted by the computer to indicate that something requires the user's attention.
bells and whistles
Fancy features added to software or hardware; usually indicates features that are more flashy than practical.
Explanation : Constraint logic programming is a form of constraint programming, in which logic programming is extended to include concepts from constraint satisfaction. A constraint logic program is a logic program that contains constraints in the body of clauses. An example of a clause including a constraint is A(X,Y) :- X+Y>0, B(X), C(Y). In this clause, X+Y>0 is a constraint; A(X,Y), B(X), and C(Y) are literals like in regular logic programming. Intuitively, this clause tells one condition under which the statement A(X,Y) holds: this is the case if X+Y is greater than zero and both B(X) and C(Y) are true.
