A point on a chart that marks the beginning of a significant move, either up or down.

An inflection point is a spot near the x-axis on a magnetic signal waveform where the curve changes direction. Inflection points generally occur on digital "1's" and "O's" at 2.95 bits per millimeter (75 bits per inch) but only on the zeros at 8.27 bits per millimeter (210 bits per inch). The presence of a strong evidence of these inflection points generally means that the stripe has good resolution. jitter- Jitter is a change of bit length or half-bit length from one bit to the next. A change of bit length from one bit to the next is called "bit-to-bit" jitter. A change of the half bit length from one bit to the next is called "sub-interval" jitter. For instance a change of bit length from 100 to 105 would be 5% positive jitter. A change from 100 to 90 would be 5% negative jitter.(empty) loco- See coercivity. low coercivity- See coercivity. LRC- An LRC, longitudinal redundancy check, character is a character at the end of the stripe after the data and end sentinel. If the LRC does not match (a logical calculation must be done) the data on the card, there has been a read error.

The point where reversal of curvature occurs. Same as point of contraflexure. See also "Contraflexure."

a dramatic shift where the course of computing suddenly and quickly takes off in a new direction

a period in time where something, an invention, cultural shift, whatever, causes an industry to surge ahead

a color style that provides interpolation of data
