Write a brief note on machine level language

Features[ edit ] "High-level language" refers to the higher level of abstraction from machine language. Rather than dealing with registers, memory addresses and call stacks, high-level languages deal with variables, arrays, objectscomplex arithmetic or boolean expressions, subroutines and functions, loops, threadslocks, and other abstract computer science concepts, with a focus on usability over optimal program efficiency. One thing to note about high-level programming languages is that these languages allow the programmer to be detached and separated from the machine. The responsibility and power of executing instructions have been handed over to the machine from the programmer.

A programmer uses this means of communication in order to give the computer instructions. These instructions are called "programs". Like the many natural languages we use to communicate with each other, there are many languages that a programmer can use to communicate with a computer.

Each programming language has its own set of words and rules, called the syntax of that language. If you're going to write a program, you have to follow the syntax of the language you're using, otherwise you won't be understood.

Programming languages can generally be divided in two categories: Low-level[ edit ] Image shows most programming languages and their relations from the mids up to click here for full size. The lower level in computer "languages" are: Machine code also called binary is the lowest form of a low-level language.

Machine code consists of a string of 0s and 1s, which combine to form meaningful instructions that computers can take action on. If you look at a page of binary it becomes apparent why binary is never a practical choice for writing programs; what kind of person would actually be able to remember what a bunch of strings of 1 and 0 mean?

Machine Language

Assembly language also called ASMis just above machine code on the scale from low level to high level. It is a human-readable translation of the machine language instructions the computer executes.

For example, instead of referring to processor instructions by their binary representation 0s and 1sthe programmer refers to those instructions using a more memorable mnemonic form. These mnemonics are usually short collections of letters that symbolize the action of the respective instruction, such as "ADD" for addition, and "MOV" for moving values from one place to another.

Assembly language is processor specific. This means that a program written in assembly language will not work on computers with different processor architectures. Learning about assembly language will also allow you to have more control as a programmer and help you in debugging and understanding code.

The advantages of writing in a high-level language format far outweigh any drawbacks, due to the size and complexity of most programming tasks, those advantages include: Low-level programs often use specialized functions available on only certain processors, and have to be rewritten to run on another computer.

For example, Java, a high-level programming language, is capable of painting a functional window with about five lines of code, while the equivalent assembly language would take at least four times that amount. High-level[ edit ] High-level languages do more with less code, although there is sometimes a loss in performance and less freedom for the programmer.High-level programming language In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer.

An assembly language is a low-level programming language for microprocessors and other programmable devices. It is not just a single language, but rather a group of languages. An assembly language implements a symbolic representation of the machine code needed to .

The process of compiling a high-level language program into machine language can take a considerable amount of computer time. Interpreter programs were developed to execute high-level language programs directly, although much more slowly. These tips—and examples—will help you write a heartfelt message.

A high-level language is a more advanced programming language designed to be understood by the programmer. As far the comparison of high-level vs machine language is concerned, both languages supplement each other since they are a communication bridge between the programmer and the hardware of a computer system.
