Which language is used by the CPU to process instructions?

Which language is used by the CPU to process instructions?

machine language instructions
In computer programming, machine code is any low-level programming language, consisting of machine language instructions, which is used to control a computer’s central processing unit (CPU).

What is the only language that the CPU understands?

A CPU understands a low level “machine code” language (also known as “native code”). The language of the machine code is hardwired into the design of the CPU hardware; it is not something that can be changed at will.

What happens when machine code is processed by the CPU?

The CPU itself contains a so called instruction decoder, which reads the native binary number by number and for each opcode it reads it gives power to the circuit of the CPU that implement this particular opcode. there are opcodes, that address memory, opcodes that load data from memory into registers and so on.

How does assembly language gets translated into machine language in microprocessor?

The Assembler (a program) translates assembly code into machine code. Assembler language is just a more readable version of machine language (machine language in symbolic form instead of binary form). You write Assembly code; Assembler translates it into machine code; Control unit runs machine code.

How a computer language is created?

Just write down some instructions and some rules for what they do, and voila, you’ve created a programming language. Of course, in most instances, programming languages don’t start as exercises in specification writing. Instead, one starts with a program that actually does something with the programming language.

How does computer language work?

Almost all programming languages work the same way: You write code to tell it what to do: print(“Hello, world”). The code is compiled, which turns it into machine code the computer can understand. The computer executes the code, and writes Hello, world back to us.

How does a computer understand a programming language?

At the hardware level, computers understand one language, called machine language (also called object code). This source file is then passed to a program called a compiler which translates the source language to object code in binary form and writes that to another file called the program.

What is the only language that a computer understands directly Mcq?

: b Explanation: The Computer understands only binary language which is written in the form of 0s & 1s.

How is machine language processed?

A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file.

How is assembly language different from machine language?

Machine language is the low level programming language. Assembly language is the more than low level and less than high-level language so it is intermediary language. Assembly languages use numbers, symbols, and abbreviations instead of 0s and 1s.

How does assembly language translate into machine language?

A tool called “assembler” converts the assembly code into machine code and a tool called “linker” connects multiple machine-code files into one single executable (. EXE under Windows) file.

How is a machine language different from an assembly language?

Machine language is the low level programming language. Machine language can only be represented by 0s and 1s. Assembly languages use numbers, symbols, and abbreviations instead of 0s and 1s. …

What are the limitations of compiler design?

Resource limitations led to the need to pass through the source code more than once. A compiler for a relatively simple language written by one person might be a single, monolithic piece of software. However, as the source language grows in complexity the design may be split into a number of interdependent phases.

What is the difference between cross compiler and decompiler?

A compiler that can run on a computer whose CPU or operating system is different from the one on which the code it produces will run is called a cross-compiler. A bootstrap compiler is written in the language that it intends to compile. A program that translates from a low-level language to a higher level one is a decompiler.

How hard is it to write a compiler?

As for compilers, at their very simplest, they can be little more than “cut and paste” programs. You could write a very simple, non-optimizing, “high level language” that just clusters together simple assembly language instructions without a whole lot of effort.

Can two compilers produce the same binary from the same source code?

There is no reason to assume that any two compilers produce the same binary from the same source code, likewise there is no reason to assume that any assembler is able to assemble the output of any compiler.
