periférico

Periférico is a term used in Portuguese and Spanish to describe something located on or relating to the outer edge or boundary of a space or object. The word derives from Greek peri- “around” and pherein “to bear” and is used across disciplines to indicate peripheral or external position.

In anatomy and medicine, periférico describes structures away from the center of the body. Examples include the peripheral nervous system and peripheral arteries. The term contrasts with central or proximal parts and is common in medical descriptions and diagnoses.

In computing, periféricos or peripheral devices are equipment that connects to a computer to add input, output, or storage capabilities. Examples include keyboards, mice, printers, scanners, external drives, and network interfaces. They typically connect via USB, Bluetooth, or other interfaces and are distinguished from internal components.

In urban planning and transport, the periphery of a city refers to its outer areas or outskirts. The term is frequently used in road naming and infrastructure, especially in Spanish- and Portuguese-speaking countries, where “periférico” may denote peripheral or belt routes (for example, an Anel Periférico). It is also used to describe suburban or peripheral neighborhoods in planning contexts.

Overall, periférico serves as a versatile descriptor for things located on the edge, outer regions, or external parts, across language, science, technology, and infrastructure.
