I-VLAN Isolation Function ye-Ethernet Switch Ngaphambi kokuqonda, shintsha umsebenzi wokuhlukanisa we-VLAN, siqala ukuqonda ukushintshwa kwe-ethernet: Iswishi ye-Ethernet isekelwe ekushintsheni kwedatha yokudlulisa ye-Ethernet, shintsha imbobo ye-Ethernet ngayinye ingaxhunywa kumsingathi, ngokuvamile isebenze kumodi ye-duplex egcwele, c...

I-Optical fiber transceiver iyithuluzi lokuguqula i-photoelectric eliguqukayo nelisebenzayo elidlala indima ebalulekile ku-multi-protocol photoelectric hybrid LAN. Manje, ukuze kutholwe kangcono futhi kuqedwe amaphutha esixhumanisi, amanye ama-optical fiber transceivers ane-link failover (LFP) kanye ne-remote fault (FEF)...

Masizuze ukuqonda okujulile kwe-IEEE802.11a kuphrothokholi ye-WIFI, okuyiphrothokholi yokuqala yebhendi yefrikhwensi ye-5G. 1) Ukutolikwa Kwephrothokholi: I-IEEE 802.11a iyindinganiso ebuyekeziwe yezinga lokuqala le-802.11 futhi yavunywa ngo-1999. Iphrothokholi ewumongo ye-802.11a standa...

Kokubili i-IEEE802.11b kanye ne-IEEE802.11g asebenza kubhendi yefrikhwensi engu-2.4GHz. Ake sibheke la maphrothokholi amabili ngokulandelana ukuze akusize uthole ukuqonda okujulile kwamazinga ezivumelwano ezihlukene. I-IEEE 802.11b indinganiso kumanethiwekhi endawo angenantambo. Imvamisa yenkampani yenethiwekhi ...

Kumanethiwekhi angenawaya, kunemiqondo eminingi namaphrothokholi ahilelekile. Ukuze sisize kangcono wonke umuntu abe nomqondo ocacile, sizowuchaza ngokombono wokuhlukanisa. 1. Ngokomehluko ekufakweni kwenethiwekhi: Amanethiwekhi angenantambo angahlukaniswa njengenethiwekhi yendawo engenantambo ...

Inani elikhulu ledatha lenziwe kuphrothokholi ye-IEEE802.11 ku-WiFi, futhi ukuthuthukiswa kwayo komlando kufinyezwa kanje. Isifinyezo esilandelayo akulona irekhodi eliphelele nelinemininingwane, kodwa sichaza izimiso ezijwayelekile ezisetshenziswa emakethe njengamanje. I-IEEE 802.11, eyakhiwe i...
