Programming languages are broadly classified into two types.

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.

high level language vs 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.

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.

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. Debugging and maintenance Simple Quite complex.

Low level vs High level language – Difference between low and high level language

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:.

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. Our Translators page explains how low-level languages are translated into machine code.

High and Low Level Languages

Each language has a unique set of keywords words that it understands and a special syntax for organizing program instructions. High-level programming languages, while simple compared to human languages, are more complex than the languages the computer actually understands, called machine languages. Each different type of CPU has its own unique machine language. It is not limited by the computer or for one specific job.

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.
