What are definitions of LOW LEVEL languages and HIGH LEVEL languages?
Answers
A low-level language is a type of programming language that contains basic instructions recognized by a computer. ... Two common types of low-level programming languages are assembly language and machine language. Software programs and scripts are written in high-level languages, like C#, Swift, and PHP.
Answer:
High Level Languages
When we think about computer programmers, we are probably thinking about people who write in high-level programming languages.
High level languages are written in a form that is close to our human language, enabling to programmer to just focus on the problem being solved.
No particular knowledge of the hardware is needed as high level languages create programs that are portable and not tied to a particular computer or microchip.
These programmer friendly languages are called ‘high level’ as they are far removed from the machine code instructions understood by the computer.
Examples include: C++, Java, Pascal, Python, Visual Basic.
Advantages
Easier to modify as it uses English like statements
Easier/faster to write code as it uses English like statements
Easier to debug during development due to English like statements
Portable code – not designed to run on just one type of machine
Low Level Languages
Low level languages are used to write programs that relate to the specific architecture and hardware of a particular type of computer.
They are closer to the native language of a computer (binary), making them harder for programmers to understand.
Examples of low level language:
Assembly Language
Machine Code
Assembly Language
Few programmers write programs in low level assembly language, but it is still used for developing code for specialist hardware, such as device drivers.
It is easy distinguishable from a high level language as it contains few recognisable human words but plenty of mnemonic code.
Advantages
Can make use of special hardware or special machine-dependent instructions (e.g. on the specific chip)
Translated program requires less memory
Write code that can be executed faster
Total control over the code
Can work directly on memory locations
Machine Code
Programmers rarely write in machine code (binary) as it is difficult to understand.
