Ethernet splitter<\/strong><\/h2>\n\n\n\n

Ethernet splitter je jednoduch\u00e9 pas\u00edvne zariadenie, ktor\u00e9 sa objavilo na za\u010diatku v\u00fdvoja internetu. V tom \u010dase sa internet \u010dasto pren\u00e1\u0161al cez telef\u00f3nne linky a sign\u00e1l obsahoval dve zlo\u017eky:<\/p>\n\n\n\n

  • N\u00edzkofrekven\u010dn\u00fd hlasov\u00fd sign\u00e1l<\/strong>,<\/li>\n\n\n\n

    Splitter obsahoval filtre, ktor\u00e9 kombinovan\u00fd sign\u00e1l rozdelili na dva: hlas a Ethernet. T\u00fdm sa zabr\u00e1nilo ru\u0161eniu. Osoba, ktor\u00e1 telefonovala, nepo\u010dula vysokofrekven\u010dn\u00fd \u0161um z prenosu d\u00e1t, a hlasov\u00fd sign\u00e1l neovplyv\u0148oval internetov\u00e9 pripojenie.<\/p>\n\n\n\n

    Dnes sa pojem Ethernet splitter<\/em> \u010dasto nespr\u00e1vne pou\u017e\u00edva na ozna\u010denie jednoduch\u00fdch unmanaged switchov.

Nepotrebuj\u00fa \u017eiadnu konfigur\u00e1ciu. Najjednoduch\u0161ie switche s jedn\u00fdm vstupn\u00fdm a dvoma v\u00fdstupn\u00fdmi portami sa niekedy naz\u00fdvaj\u00fa splittery, hoci to nie je spr\u00e1vne.<\/p>\n\n\n

    Ethernet switch<\/strong><\/h2>\n\n\n\n

    Ethernet switch je akt\u00edvne sie\u0165ov\u00e9 zariadenie, ktor\u00e9 umo\u017e\u0148uje pripoji\u0165 viacer\u00e9 zariadenia k rovnak\u00e9mu internetov\u00e9mu zdroju a vytvori\u0165 intern\u00fa sie\u0165 na prenos d\u00e1t medzi zariadeniami. To umo\u017e\u0148uje komunik\u00e1ciu medzi zariadeniami v lok\u00e1lnej sieti (LAN). Jednoduch\u00fdm pr\u00edkladom je streamovanie videa z telef\u00f3nu na telev\u00edzor pomocou AirPlay (pre iPhone) alebo Google Cast (pre zariadenia s Androidom).<\/p>\n\n\n

    Typy Ethernet switchov<\/strong><\/h3>\n\n\n\n
      \n
    • Z\u00e1kladn\u00e9 switche<\/strong>: Ide o unmanaged switche, ako napr\u00edklad tie zabudovan\u00e9 v Wi-Fi routeroch. Zvy\u010dajne maj\u00fa 2 alebo 4 porty, nevy\u017eaduj\u00fa konfigur\u00e1ciu a s\u00fa ve\u013emi jednoduch\u00e9 na pou\u017eitie.<\/li>\n\n\n\n

        \n
      • Obmedzenie r\u00fdchlosti<\/strong> na konkr\u00e9tnych portoch, aby jedno zariadenie nevyu\u017e\u00edvalo cel\u00fa \u0161\u00edrku p\u00e1sma.<\/li>\n\n\n\n
