System: A collection of interrelated components that work together to achieve a common goal or objective. Think of it like a team, where each member plays a specific role, but they all collaborate to achieve a shared objective.
Concept: The idea of a system is useful to explain both the external reality as well as the internal one. A system is simply an organized set of components that are coordinated to perform a designated function. All the components of the system are in some way related to each other.
Example: Consider a car - it is made up of an engine, wheels, brakes, and other related items. Every part plays a unique task, but collectively they are responsible for making the car move.
A system is described by its objectives, components, communication among components, and environment in which it works.
Natural Systems: Systems that exist in nature and operate independently of human involvement. Governed by natural laws and processes.
Artificial Systems: Systems created and developed by people to fulfill specific needs or purposes.
Computer System: A complex system designed to process data and perform tasks according to a set of instructions.
Objective: Perform computations, process data, and execute tasks efficiently.
Components:
Environment: Power supply, Network, Peripherals (printers, scanners, external discs).
Von Neumann Architecture: A computer paradigm that defines a system where hardware has four primary components: Memory, CPU, Input mechanisms, and Output mechanisms.
Core Components:
Execution Cycle:
