Programming languages are broadly classified into two types. JavaScript Tutorials jQuery Tutorials. Low-Level Languages are challenging to learn and understand.

Difference Between High-Level Language and Low-Level Language

In computer science , a high-level programming language is a programming language with strong abstraction from the details of the computer. In contrast to low-level programming languages , it may use natural language elements , be easier to use, or may automate or even hide entirely significant areas of computing systems e. The amount of abstraction provided defines how "high-level" a programming language is. In the s, high-level programming languages using a compiler were commonly called autocodes. The first significantly widespread high-level language was Fortran , a machine-independent development of IBM's earlier Autocode systems. Algol , defined in and by committees of European and American computer scientists, introduced recursion as well as nested functions under lexical scope. It was also the first language with a clear distinction between value and name-parameters and their corresponding semantics.

A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU Central Processing Unit. Each programming language contains a unique set of keywords and syntax, which are used to create a set of instructions. Thousands of programming languages have been developed till now, but each language has its specific purpose. These languages vary in the level of abstraction they provide from the hardware. Some programming languages provide less or no abstraction while some provide higher abstraction. Based on the levels of abstraction, they can be classified into two categories:. The image which is given below describes the abstraction level from hardware.

We already learn't about low level and high level language. We have seen their advantages and their disadvantages. Programs in low level language are written either in binary or assembly language. They do not require any compilation or interpretation. It interact directly with the registers and memory.

High and Low level Programming Languages

High-level language and low-level language are the types of programming languages. The prior difference between high level and low-level language is that the high-level language is easily interpreted by programmers but not machines whereas low-level language can be easily understood by machines but not by humans. The low-level language contains machine language and assembly language. Assembler is required while machine language is directly executed. Memory efficiency Low High Comprehensibility Understandable Hard to understand Portability and machine dependency Portable and runnable in any platforms. Non-portable and machine dependent.

The main difference between high level language and low level language is that, Programmers can easily understand or interpret or compile the high level language in comparison of machine. On the other hand, Machine can easily understand the low level language in comparison of human beings. Attention reader! Writing code in comment? Please use ide. Skip to content. Related Articles.

Low Level Languages do not have much community support. On the contrary, low-level language is machine amiable which means it is interpreted by machines easily. It is quite difficult to program in a low level language but it is the opposite with a high level language. The CPU directly executes Those instructions.

High and Low Level Languages

When we think about computer programmers, we are probably thinking about people who write in high-level programming languages. Our Translators page explains how high-level languages are translated into machine code. Low level languages are used to write programs that relate to the specific architecture and hardware of a particular type of computer. Few programmers write programs in low level assembly language , but it is still used for developing code for specialist hardware, such as device drivers.

Глядя на оживающий монитор, он подумал, известно ли Стратмору, что в лаборатории систем безопасности нет ни души. Подходя к шифровалке, он успел заметить, что шторы кабинета шефа задернуты. Это означало, что тот находится на рабочем месте. Несмотря на субботу, в этом не было ничего необычного; Стратмор, который просил шифровальщиков отдыхать по субботам, сам работал, кажется, 365 дней в году.

 - Усталая улыбка промелькнула на его лице.  - И потом, я не. Рядом со мной Сьюзан Флетчер. В тот момент Сьюзан поняла, за что уважает Тревора Стратмора. Все эти десять лет, в штиль и в бурю, он вел ее за .


This is called Assembly language. Such languages are still in use today particularly when speed is essential or in cases when the programmer.


 - Некто шантажирует АНБ и через несколько дней умирает - и мы не несем ответственности. Готов поспорить на любую сумму, что у партнера Танкадо будет иное мнение. Что бы ни произошло на самом деле, мы все равно выглядим виновными.

Но, приблизившись к освещенному пространству открытого ангара, Беккер понял, что его вопросы лишены всякого смысла. Внутри не было никакого лирджета. Он несколько раз моргнул затуманенными глазами, надеясь, что это лишь галлюцинация. Увы, ангар был пуст. О Боже.

Хотя Бринкерхофф всегда мечтал о настоящей карьере в агентстве, он вынужден был довольствоваться положением личного помощника - бюрократическим тупиком, в который его загнала политическая крысиная возня. Тот факт, что он работал рядом с самым влиятельным человеком во всем американском разведывательном сообществе, служил ему малым утешением. Он с отличием окончил теологическую школу Андовери колледж Уильямса и, дожив до средних лет, не получил никакой власти, не достиг никакого значимого рубежа. Все свои дни он посвящал организации распорядка чужой жизни.

    Each language has a unique set of keywords words that it understands and a special syntax for organizing program instructions.
