Bar Graph

A diagram consisting of a sequence of vertical or horizontal bars or rectangles, each of which represents an equal interval of the values of a variable, and has height proportional to quantities of the phenomenon under consideration in that interval.
The following bar graph shows the incomes for two companies (the blue one and the red one). The first six months of the year are represented on the horizontal line (the x-axis) and the income (in million dollars) for each corresponding month is on the vertical line (the y-axis) represents . 

Base

Base of a polygon (triangle, parallelogram, ...) is one of its sides, usually the one in the bottom. 
Base of a solid (cube, pyramid, cylinder, cone, ...) is the area of supporting the body, usually the one in the bottom.

Bit

Abbreviation for binary digit represented by 0 or 1.

Bound

A set of numbers, denoted, S, is bounded if there exists two fixed real numbers, L and U, such that L < x < U, for every x in S.  For example, the set {1+1/n}, where n is positive integers, is bounded, for taking L and U such that L  < 1 and U > 2.

Bracket
