Are instruction set and assembly language the same thing?

Question

I was wondering if instruction set and assembly language are the same thing?

If not, how do they differ and what are their relations?

Thanks and regards!

Answer 1

The instruction set is composed by all the instructions a processor can execute, while assembly is the programming language that uses these instructions to make programs.
In other words, the instruction set is just a group of bytes a CPU can understand, but you can't do anything useful with them (think the instructions as the letters of the alphabet) while assembly is a language which lets you combine these instructions (or letters) to make a program (something like a speech).
