According_Builder@reddit
The ISA is essentially the flavor of assembly for a particular CPU family and the features they support. This includes things like how many registers, what kinds of registers, and the operations that can be done such as SIMD operations.

It's how developers interface with the CPU at the lowest level.
The ISA defines the instructions and their binary encoding.

ISA is just the set of things that the CPU can be commanded to do

The ISA "Instruction Set Architecture" is the model that defines how the CPU works and the instruction the CPU understands.
The ISA defines how many registers the CPU has, what data types it supports, how it access memory, etc. It also defines a list of instructions software developers use.

It just describes how the hardware is controlled by software. Think of it like the "language" that the CPU speaks.
