In terms of programming, a high-level programming language is one which has a relatively high level of abstraction, and manipulates conceptual functions in a structured manner. A low-level programming language is one like assembly language that contains commands closer to processor instructions.
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.g. memory management), making the process of developing a program ...
A program written in a low-level language can be made to run very quickly, with a small memory footprint. An equivalent program in a high-level language can be less efficient and use more memory. Low-level languages are simple, but considered difficult to use, due to numerous technical details that the programmer must remember.
The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.

Initially, all programming languages at a higher level than assembly were termed "third-generation", but later on, the term "fourth-generation" was introduced to try to differentiate the (then) new declarative languages (such as Prolog and domain-specific languages) which claimed to operate at an even higher level, and in a domain even closer ...
The HLA v2.x assembler supports the same low-level machine instructions as a regular low-level assembler, while high-end assemblers also support high-level-language-like statements, such as IF, WHILE, and so on, and fancier data declaration directives such as structures-records, unions, and even classes.
Diglossia refers to the use by a language community of two languages or dialects, a "high" or "H" variety restricted to certain formal situations, and a "low" or "L" variety for everyday interaction. [1] This article contains a list of nations, cultures, or other communities which sources describe as featuring a diglossic language situation.
A trade language will typically need to explicitly explain more of the context than a dialect which can assume a high level of shared context. Because a low-context setting cannot rely on a shared understanding of potentially ambiguous messages, low-context cultures tend to give more information or to be precise in their language. [38]
