Detailed explanation-1: -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.
Detailed explanation-2: -Generally, a mnemonic is a symbolic name for a single executable machine language instruction (an opcode), and there is at least one opcode mnemonic defined for each machine language instruction. Each instruction typically consists of an operation or opcode plus zero or more operands.
Detailed explanation-3: -Examples of mnemonics in assembly language include ADD (which odd data), MUL (which multiplies data), MOV (which moves data), JUMP (which performs a jump operation).
Detailed explanation-4: -Mnemonics are memory devices that help learners recall larger pieces of information, especially in the form of lists like characteristics, steps, stages, parts, etc.
Detailed explanation-5: -Mnemonic codes are those codes that consist of alphabets or abbreviations as symbols for codifying a piece of information. E.g. HQ for headquarters, DLI for Delhi in train bookings.
