Operand : as it applies to web development technology
In programming as it is with mathematics the term "operand" refers to a literal value or variable that is to be operated on using one of the many operators available to the programmer. Operands are the values at work in an expression.
3 > 4
In the expression above "3" is the left operand, "4" is the right operand, and the ">" symbol is the operator. All of which make up an expression that returns a value of "false" because in this case 3 is not greater than 4.
