Study Notes
Computer Terminology
- A complete computer encompasses hardware, operating system, software, and peripheral equipment, referred to as a computer system.
- A nominally complete computer includes all necessary components for full functionality, often termed a working system.
Computer Functions and Purposes
- The primary function of a computer is to process data, perform calculations, and execute tasks according to instructions or programs.
- Early computers were originally designed for mathematical calculations and data processing, focusing on tasks like census calculations and scientific research.
Control Systems and Devices
- Control systems that utilize computers include a variety of devices such as industrial machines, robotics, and automated systems, which manage and direct processes.
- Simple special-purpose devices that function as control systems often involve embedded systems, like digital thermostats or home appliances.
Networking and Systems Integration
- A group of connected computers functioning together is known as a computer network. This allows for resource sharing, communication, and collaborative tasks.
- The Internet is powered by distributed networks of interconnected computers, facilitating global data exchange and communication.
