Computer Languages

High level languages are more understandable to humans compared to low-level languages. Examples are Python, Java or C#.
Less memory efficient compared to low-level languages, but are easier to write, maintain, and debug
Supports multi-threading and can be run on any platform with the right interpreter or compiler

Assembly language is a low-level programming language for a computer or other programmable device.
Directly corresponds to machine language instructions which are specific to each computer architecture
Harder to write and understand, but gives programmer more control over hardware
Requires assembler to convert Assembly code to executable machine code

Machine code is a computer programming language that is directly understandable by a computer’s CPU.
It is written in binary and is very hard for humans to read or write.
It is the most fundamental level of programming and provides higher execution speed and more efficient use of memory.

An interpreted language is a type of programming language for which implementation executes instructions directly, without previously compiling into machine-language instructions.
Execution is slower than compiled languages as each instruction is read, interpreted and executed every time the program runs.
Examples include Python, JavaScript and Ruby.

A compiled language is a programming language whose implementations are typically compilers and not interpreters.
Involves converting source code into machine code before execution.
Once compiled, execution is faster than interpreted languages.
Examples include C, C++ and Swift.

Selection of a language for a programming task depends on factors such as the nature of task, expected speed of execution, hardware and software resources available, skill level of programmers available, etc.
Understanding pros and cons of different languages helps in making this decision. For instance, for tasks needing direct manipulation of hardware registers or memory, Assembly or C might be more appropriate. For web based applications, a language like JavaScript might be best.
