PC Components (Personal Computer)
A computer (or computer system) can be defined as a electronic program-based automatic data processing .
The configuration of a system is the list of components of that system.
The architecture of a system is the configuration along with the relationships between the elements.
A computing system is a two-part assembly:
- HARDWARE - is a term that covers all the electronic and mechanical components of the computing system (physical part);
- SOFTWARE - is a term that covers all the programs used in a computing system. Within the software component is distinguished an element that ensures the interconnection of all components of the computing system, transforming them into an entity - the computer and ensuring its interconnection with the external environment. This software is called an operating system.
- The motherboard - is the physical and logical support for the other components, being the hardware component that provides the physical interconnection of all elements in the configuration of a computing system;
- The microprocessor - on most current computers, this is an INTEL microprocessor, or one of the other INTEL-compliant processors;
- Input / output equipment set - including keyboard, mouse, scanner, CD-ROM, or barcode readers as input devices. The most common output devices are printers and monitors;
- A set of fast memory and slower storage - to save and retrieve data and programs;
- A bus / bus set - to connect the microprocessor to memory or adapters that make it possible to attach other devices via their ports or extension connectors. Buses can be thought of as electronic highways interconnecting the hard components of a PC;
