olemus
OSI mudeli lülikihis töötav võrguseade
kohtvõrgu segmentide ühendamiseks
(näiteks Ethernetil põhinevas kohtvõrgus),
edastab liiklust MAC-aadresside põhjal,
mis on muude seadmete võrguliidestes,
erikiibi abil peetavate aadressitabelite järgi;
kommuteerimine toimub riistvaras

Techopedia:
a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded; it uses hardware based switching techniques to connect and transmit data in a local area network (LAN)
