Explanation :A lead time is the latency between the initiation and execution of a process. For example, the lead time between the placement of an order and delivery of a new car from a manufacturer may be anywhere from 2 weeks to 6 months. One Business Dictionary defines “manufacturing lead time” as the total time required to manufacture an item, including order preparation time, queue time, setup time, run time, move time, inspection time, and put-away time. For make-to-order products, it is the time taken from release of an order to production and shipment. For make-to-stock products, it is the time taken from the release of an order to production and receipt into finished goods inventory.

Explanation :MNEMONIC: English word MNEMONIC means “A device such as a pattern of letters, ideas, or associations that assists in remembering something.” So, its usually used by assembly language programmers to remember the “OPERATIONS” a machine can do, like “ADD” and “MUL” and “MOV” etc. This is assembler specific.
OPCODE: It is a number interpreted by your machine(virtual or silicon) that represents the operation to perform.
In computer assembler (or assembly) language, a mnemonic is an abbreviation for an operation. It’s entered in the operation code field of each assembler program instruction. for example AND AC,37 which means AND the AC register with 37. so AND, SUB and MUL are mnemonic. They are get translated by the assembler.
BYTECODE: Same as machine code, except, its mostly used by a software based interpreter(like Java or CLR).
MACHINE CODE: It is the sequence of numbers that flip the switches in the computer on and off to perform a certain job of work – such as addition of numbers, branching, multiplication, etc etc. This is purely machine specific and well documented by the implementers of the processor..
