A sound card is a semiconductor circuitry that allows you to work with sound on a computer. The very first computers, for about 10 years, did not involve the use of sounds, and all that could be heard from them was the clicks of various electronic-mechanical relays and the monotonous beeping of the built-in speaker, which voiced the state of the system and the operation of some applications and games.
The progenitor of the sound card can be considered a device from Covox Inc, which was connected to the printer port of the IBM PC and could play digital monaural sound. In addition, this fact suggests that Covox was the first external sound card.

- Connecting a large number of cables, including from microphones, a mixing console, an amplifier, to the block of an external sound card, is much easier than hanging this bundle of wires together with others on one computer.
- The portable sound card can be connected to any mobile device having the required connector, for example, to a laptop.
