Computer system
(also computing system, computer environment)
Computer system definition
A computer system represents a cohesive combination of hardware, software, and networking elements configured to execute specific functions or a collection of tasks. The system comprises the central processing unit (CPU), memory, storage devices, input/output devices, and various peripherals, which collaborate to process, store, and manage data. Computer systems can vary from basic embedded systems to intricate distributed networks involving interconnected devices, as seen in cloud computing.
Computer system examples
- Personal computer (PC): A general-purpose computing device designed for individual use, typically consisting of a CPU, memory, storage, and various input/output devices.
- Server: A computer system dedicated to managing network resources, providing services, and processing requests from other devices, often in a client-server architecture.
- Embedded system: A specialized computer system integrated into larger devices, like automobiles or home appliances, designed to perform specific functions with minimal resources.
Comparing computer systems to other similar terms
Computer systems are more comprehensive than computer hardware because they also encompass software and networking components. While a computer network refers to the interconnection of multiple computer systems, a computer system refers to an individual unit with its own hardware, software, and networking components.
