3. Relationship Between Hardware and Software in Computer Systems
Hardware and software are integral components of a computer system, working in tandem to perform tasks effectively. The relationship is maintained through interfaces like Instruction Set Architecture and operating systems, which manage resources. The chapter explores various levels of software abstraction, the impact of software on hardware design, and highlights the importance of security and performance optimization.
