A computer system is a synergy of several interdependent elements that work in unison to perform complex operations. These elements include hardware, software, data, and users, all coordinated by the operating system (OS). The OS ensures that hardware resources are allocated efficiently and software applications run smoothly. The organization of a computer system can be divided into three main hardware, software, and user interaction. Understanding this organization is key to appreciating how an operating system manages resources and facilitates communication between users and machines.
