I-VLAN Isolation Function ye-Ethernet Switch Ngaphambi kokuqonda, tshintshela umsebenzi wokuhlukanisa i-VLAN, okokuqala siqonde ukutshintshwa kwe-ethernet: Ukutshintsha kwe-Ethernet kusekelwe kwi-Ethernet yokudlulisa idatha yokudlulisa, i-Ethernet yokutshintsha i-port nganye inokudibaniswa kwi-host host, isebenza ngokubanzi kwimodi ye-duplex epheleleyo, c...

I-Optical fiber transceiver iyisixhobo esiguquguqukayo nesisebenzayo sokuguqula i-photoelectric edlala indima ebalulekileyo kwi-multi-protocol photoelectric hybrid LAN. Ngoku, ukuze ubone ngcono kwaye uphelise iimpazamo zekhonkco, ezinye ii-transceivers zefiber optical zine-failover yekhonkco (LFP) kunye ne-remote fault (FEF) ...

Masizuze ukuqonda okunzulu kwe-IEEE802.11a kwi-protocol ye-WIFI, eyiprotocol yokuqala ye-5G frequency band. 1) Utoliko lweProtocol: IEEE 802.11a ngumgangatho ohlaziyiweyo womgangatho wokuqala we-802.11 kwaye wamkelwa ngo-1999.

Zombini i-IEEE802.11b kunye ne-IEEE802.11g zisebenza kwi-band frequency ye-2.4GHz. Makhe sijonge ezi protocols zimbini zilandelelana ukukunceda ufumane ukuqonda okunzulu kwemigangatho yemithetho yomthetho eyahlukeneyo. IEEE 802.11b ngumgangatho kuthungelwano lwengingqi olungenazingcingo. I-frequency carrier yayo ...

Kwiinethiwekhi ezingenazingcingo, kukho iikhonsepthi ezininzi kunye neeprothokholi ezibandakanyekayo. Ukunceda ngcono wonke umntu abe nombono ocacileyo, siya kuyichaza ngokwembono yokuhlela. 1. Ngokomahluko wokugubungela inethiwekhi: Iinethiwekhi ezingenazingcingo zingahlelwa njengeNethiwekhi yeNdawo eWireless ...

Isixa esikhulu sedatha senziwe kwi-IEEE802.11 protocol kwi-WiFi, kwaye uphuhliso lwayo lwembali lushwankathelwa ngolu hlobo lulandelayo. Esi sishwankathelo silandelayo asilorekhodi elibanzi neneenkcukacha, kodwa endaweni yoko sichaza iiprothokholi eziphambili ezisetyenziswa ngoku kwimarike. IEEE 802.11, yenziwe i...
