Questions & Answers

Q: What is Instruction Set Architecture (ISA) and why is it important?

ISA defines a computer's operations and is vital for software-hardware interaction, enabling software compatibility across different hardware implementations.

Q: How does ISA virtualization facilitate software compatibility across different processors?

ISA virtualization emulates the instruction set of one processor on another, allowing applications designed for one processor to run on a different architecture.

Q: What is the role of ISA in reducing the cost of computers?

ISA allows software to run on various implementations, driving competition and innovation, ultimately leading to cost reduction by offering multiple performance and cost options.

Q: How does ISA abstraction simplify the implementation of software applications?

ISA abstracts hardware details, providing a consistent interface for software developers, simplifying the creation of applications that can run on different hardware architectures.
