RCA
— technically, the RCA connector can be used for different types of signal, but in this case, the simplest linear interface for analogue audio transmission is meant. In such an interface, one connector allows you to transmit only one channel of sound. So RCA jacks are usually installed in pairs — for the left and right stereo channel. Due to such bulkiness, this interface is practically not used in headphones and is very rarely found in “purely computer” speakers, but it is quite popular in stationary audio equipment: transmitting each channel via a separate wire improves sound quality compared to simpler interfaces like mini-Jack 3.5 mm. So a sound card with an RCA output can be useful, for example, for building a home audio system based on a computer.
