Incommunications orcomputer systems, aconfiguration of a system refers to the arrangement of each of its functional units, according to their nature, number and chief characteristics. Often, configuration pertains to the choice of hardware, software,firmware, and documentation. Along with its architecture, the configuration of a computer system affects both its function and performance.

The configuration of a computer is typically recorded in aconfiguration file. In modern computer systems, this iscreated and updated automatically as physical components are added or removed. Applications may assume that the configuration file is an accurate representation of the physical configuration and act accordingly.^[1]

Most modern computer systems provide a mechanism called thesystem settings (or "control panel") that permits users to set their preferences. These include systemaccessibility options (such as the default size of thesystem font), brightness and contrast; security and privacy; network selection and so on.
