What you meant by machine level language?

Answer 1

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.
