The Instruction Set Architecture is the part of the processor that is visible to the programmer. The ISA serves as the boundary between software and hardware.

Further, it is the abstract model of a computing system that is seen by a machine language programmer, including the instruction set, memory address modes, processor registers, and address and data formats.

Instruction Set Architecture is related to the programming of a computer – that is, how the computer understands, what each element in its basic language means, what instructions are to be carried out and in what order, etc. The ISA basically deals with what the chip does.
