One instruction in high level language corresponds to one instruction in machine language?
No. Generally, one instruction in a high level language corresponds to many instructions in machine language.
Assembly language to machine language translation is?
Assembly language to machine code translation is a "one to one" translation process, as every individual instruction expressed in the assembly language corresponds to exactly one machine instruction. Note this does not hold for pseudo instructions or expanding macros, which are supported by some assemblers.
What is accembly language?
Assembly language is a low level language where each statement (mostly) corresponds with one machine instruction. Higher level languages, such as C and FORTRAN, generate multiple machine instructions for each statement.
Why are assemblers used?
to translate mnemonic operation codes to their machine language equivalents and assigning machine address to symbolic labels used by the programmer.
What is the process of writing specific instructions in computer language called?
A machine code program. Machine code is the native language of the machine and the only language actually understood by the machine. However, program instructions can be written using a high-level programming language that the computer can translate into machine code using another machine code program called a compiler.
What is the Difference between machine op and pseudo op?
A pseudo-op is an assembly language instruction that specifies an operation of the assembler i.e about the base register & its contents e.g. USING instruction. On the other hand, a machine-op instruction. That represents a machine instruction to the assembler e.g. BR instruction is a machine-op instruction
One instruction in high level language corresponds to one instruction in machine language?
No. Generally, one instruction in a high level language corresponds to many instructions in machine language.
What is Operation Code OpCode?
an opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed. Their specification and format are laid out in the instruction set architecture of the processor in question (which may be a general CPU or a more specialized processing unit). Apart from the opcode itself, an instruction normally also has one or more specifiers foroperands (i.e. data) on which the operation should act, although some operations may have implicit operands, or none at all. There are instruction sets with nearly uniform fields for opcode and operand specifiers, as well as others (the x86architecture for instance) with a more complicated, varied length structure.by: HerLoyd

How do you add new machine language instruction to a processor intsruction set?
To add a new machine language instruction to an processor instruction set, you need to replace the microcode of the processor.
What is the need of addressing mode?
The various addressing modes that are defined in a given instruction set architecture define how machine language instructions in that architecture identify the operand (or operands) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere.
What is the Language programmer writes one mnemonic instruction for each machine level instruction?
It is an assembler language programmer
What is a micro-instruction?
microinstruction: An instruction that controls data flow and instruction-execution sequencing in a processor at a more fundamental level than machine instructions. Note: A series of microinstructions is necessary to perform an individual machine instruction.a micro instruction specifies one or more micro oprations for the system.

What you meant by machine level language?
Machine level language is the native language of the machine, also known as machine code. Every machine has it's own version of machine code and must be written entirely in binary. The machine has a number of primitive "operation codes" each of which maps to a unique binary value. For instance, if the machine has an 8-bit instruction register, it can have as many as 256 unique operation codes. By setting the instruction register, we can instruct the machine to perform a simple task. By rapidly changing the value in the instruction register, we can perform a series of operations in succession. Other registers can be used to store any operands required by an operation as well as to present the result of an operation and to keep track of where the next instruction is. By performing simple logical comparisons between registers we can change the value of the next instruction and thus alter the flow of execution through the sequence of instructions. All of this is achieved through machine code, and all low-level and high-level languages must be converted to machine code in order to execute a program. The machine itself can be programmed to perform this translation. The terms low-level and high-level simply give an indication of the level of abstraction between the source code and the resultant machine code. Low-level symbolic languages require very simple translations, but high-level languages require more complex translations.
Is used to translate high level language programme into machine code instruction?
Interpreter
What is a machine language?
Actual Machine level language is binary language, which contains only '0' & '1 ' and it's the extreme besic of a computer's instruction. Then comes low level language, like assembly language and so on.
