Описание PCI

штекер PCI
гнездо PCI

PCI слот - cлот на материнке из пластмассы белого цвета. Впервые появился на Пентиум-1 или на самых поздних моделях i-486. Имеет почти на порядок более высокую скорость, чем ISA, который с 2000 года на материнки не устанавливают. Первоначально использовался, в числе прочего, для подключения видеокакрт, но с конца 90-х видеокарты стали подключать через более быстрый слот AGP - как правило коричневый. Самые новые видеокарты предназначены для подключения через PCI--E.
PCI поныне остается наиболее употребительным слотом - через него подключают звуковые карты (более совершенные, чем встраиваемые в материнки) , ТВ-тюнеры, внутренние факсмодемы, дополнительные USB- и FireWire-контроллеры, АТА-контроллеры для подключения дополнительных жестких дисков и оптических дисководов (а то встроенный в материнку контроллер допускает обычно подключение лишь 4-х устройств) , сетевые карты и прочие так называемые платы расширения.
