Each mnemonic maps directly to a machine instruction code, known as an opcode. Some mnemonics map to more than one opcode, however the instruction's operand types will determine which specific opcode will be generated.
Well, let's say you have the following Assembler statement: MOV AX, 0005 Each processor (depending on the processor architecture, being some of them: SPARC, Intel 80x86, Motorola...) translates each Assembler mnemonic and register into Machine Code according to an Opcode Table. Think of an Opcode Table this way: Instruction OpCode ----------------------------------- MOV A1 ADD A2 SUB A3 MUL A4 DIV A5 ... AX B0 BX B1 CX B2 ... Each mnemonic/register has its corresponding hex code for the processor to understand the operation, so: MOV AX, 0005 Could be translated as: A1 B0 0005 Hopefully this gives you an idea of how a processor assembles code and generates machine code.
Compliers are used to convert C++ into assembly code. Then a tool called an "assembler" converts that code into machine code. Finally, a "linker" connects all of those machine code files into a single executable.

It coverts your source code into machine code so the computer can execute it.

It is partial with opcode and processor code. It is meaningless when we see it on our eyes, but it provides info instructions to Java Virtual Machine to execute that.
i) Instruction code deals only with mnemonics and its corresponding opcode but data code refers to your data like 10h which is always of 8 bits or a particular address say 8080h which is of 16 bits. ii) Data is your input to the instruction but an opcode is native to your machine. iii) Data is user specific instruction while opcode is machine specific instruction iv) You can alter data code but you cannot modify an instruction opcode.
basically compiler is that convert an object code in to machine code and machine code is directly understood by a computer. assembler and interpreter are the examples of compilers. assembler is used to convert object code of assmebly language in machine code.

3 for opcode fetch, 1 for opcode decode, 3 for operand fetch, and 3 for opcode store, for a total of 10, not including wait states.

To convert source code (.c file) to an executable (.exe) file you have to use a compiler, which is a translator of source code to machine code.
In Visual BASIC and other languages, source code refers to the code that you actually type when you are writing a program. Computers convert this code to machine code in order to be able to run the program.In Visual BASIC and other languages, source code refers to the code that you actually type when you are writing a program.

Compilers are needed to convert human readable source code into machine executable code.
IP is incremented after fetch of instruction opcode. Specifically, IP is incremented by the number of opcode bytes.
