Meaning – The term mnemonic, refers to a single character of a menu item or a button label, often the first letter, that represents a function and can be typed to select that menu item or button. The mnemonic is usually shown as the underlined character.
In computers, mnemonics are often used to make a shortcut easy to remember.
In computer programming, routine programming functions are assigned a mnemonic that is shorter in length but provides the same functionality as the original function.
In assembly language, mnemonics are used to specify an opcode that represents a complete and operational machine language instruction. This is later translated by the assembler to generate the object code.
Example of usage – “The mnemonic MOV is used in assembly language for copying and moving data between registers and memory locations.”
