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.
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.

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 simpler and more ...
A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture, memory or underlying physical hardware; commands or functions in the language are structurally similar to a processor's instructions. These languages provide the programmer with full control over ...
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream. [1] [2] For levels below level 4 only the Main tier is allowed. [1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels. [1] [2]
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 ...
High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior.
Low-level memory and hardware details must be manually managed which is often bug-prone. [2] Programs are machine-dependent, so different versions must be written for every target machine architecture. [3] The vast majority of programs are written in a third-generation programming language or a fourth-generation programming language.
