Culturally, people generally recognize that strength derives from unity and weakness is a product of disunity. 1 (one) is a number, numeral, and the glyph that represents the number. Digitised data is represented in physical devices, such as computers, as pulses of electricity through switching devices such as transistors or logic gates where “1” represents the value for “on”. This variation can lead to confusion with the glyph used for seven in other countries and so to provide a visual distinction between the two the digit 7 may be written with a horizontal stroke through the vertical line.
