Zingwe Network kwa kompyuta: mtundu ndi kugwirizana

Zingwe ntchito yomanga zomangamanga Intaneti computer, zilipo zosiyanasiyana mitundu. Pakati wotchuka - m'chakudya chokoma, wopota awiri ndi CHIKWANGWANI kuwala. ndi mfundo ya aliyense wa iwo? ndi mbali ya unsembe ambiri Kodi - zopotoka awiri?

Mitundu chingwe: coaxial

Anthu ambiri mbiri oyambirira mitundu ya zingwe ntchito kugwirizana zopezera - coaxial. Makulidwe izo ziri limafanana ndi mphamvu chingwe kundipatsako kwa computer, lakonzedwa kuti ntchito ndi zitsulo 220 V.

Kapangidwe ka kapangidwe coaxial chiri motere: pakati - ndi zachitsulo wochititsa lili mu izo wandiweyani, kutchinjiriza zambiri pulasitiki. Pamwamba pa izo - ndi kuluka zamkuwa kapena zotayidwa. Kunja wosanjikiza - chimateteza jekete.

A pawiri wa mtundu uwu LAN chingwe akhoza kunatheka chifukwa:

- BNC-cholumikizira;

- BNC-Terminator;

- BNC-T-cholumikizira;

- BNC-cholumikizira Burrell.

Taganizirani mfundo awo enieni.

BNC-cholumikizira kumafuna kuika pa chingwe malekezero ntchito mogwirizana ndi zolumikizira Burrell-T-. BNC-Terminator ntchito monga zokutira zitsulo kumulepheretsa kayendedwe ka chingwe chizindikiro. Kukhoza ntchito maukonde popanda chinthu ichi, zina zosatheka. Polumikiza kudzera maukonde mtundu chingwe coaxial zimaphatikizapo kugwiritsa ntchito terminators awiri, mmodzi amene amafuna grounding. BNC-T-cholumikizira ali chinkhoswe kugwirizanitsa PC ndi msewu waukulu. Pa kapangidwe ake, pali mipata atatu. The cholumikizira woyamba olumikizidwa kwa maukonde khadi kompyuta kudzera kumalekezero ena awiri kugwirizana ndi osiyana nsana. mtundu wina wa cholumikizira kwa coaxial chingwe - BNC-mbiya. Izo ntchito kugwirizanitsa madera osiyana a mzere, kapena kuonjezera utali wozungulira wa maukonde kompyuta.

Pakati pa mbali zothandiza nyumba ya coaxial - palibe mavuto ndi njira ya funso mmene kulumikiza zingwe ziwiri zopezera mtundu uwu. Zotha kuonetsetsa kukhudzana odalirika mawaya wochititsa, kumene, pansi pa mawonekedwe luso kudzipatula ndi chophimba gululi. Komabe, chingwe coaxial amakhudzidwa kwambiri kulowelela mu atomu. Choncho, mwambo wa kumanga Intaneti kompyuta panopa ntchito infrequently. Komabe, chofunika kwambiri pa mawu a zomangamanga gulu cha kufala kwa chizindikiro TV - kuchokera trays kapena wosamalira chingwe.

zopotoka awiri

Mwina masiku ano chifukwa zingwe kompyuta maukonde amatchedwa "zopotoka awiri". Chifukwa dzina ili? chakuti chingwe kapangidwe ka mtundu kudzapereka ochititsa pairwise. Iwo zopangidwa ndi mkuwa. Standard mtundu chingwe pansi kulingalira limapangidwa 8 mitima (a, potero, 4 awiriawiri), koma pali zitsanzo ndi ochititsa anayi. Otchedwa maukonde chingwe pinouts wa mtundu uwu (wa malumikizanidwe aliyense chingwe ndi ntchito ina yapadera) zimaphatikizapo kugwiritsa ntchito pawekha mtundu yeniyeni aliyense kondakitala.

Kunja kutchinjiriza wa peyala zopotoka anapangidwa kuchokera PVC, amene amaonetsetsa okwanira kutetezedwa zinthu conductive ku kulowelela mu atomu. Ndi zingwe isagwe wa mtundu uwu - FTP ndi STP. Mu amachita kale yoyenera ntchito zojambulazo pamwamba pa moyo zonse, lachiwiri - aliyense ochititsa lapansi. Pali kusinthidwa wa unshielded awiri zopotoka - UTP. Monga ulamuliro, zingwe zodula ndi zojambulazo. Koma iwo ayenera kugwiritsidwa ntchito pokhapokha ngati pali kufunika kufala deta apamwamba pa mtunda ndi lalikulu. Home Intaneti njira ndi loyenereradi unshielded zopotoka awiri.

Zingapo makalasi osiyana lolingana nyumba mtundu, aliyense wa iwo amatchedwa mphaka angapo kuchokera 1 mpaka 7. apamwamba chithunzi ofanana, zipangizo bwino kupereka HIV chizindikiro. Modern maukonde zingwe kuti kompyuta kusinthitsa deta kudzera Efaneti Intaneti kunyumba amati zinthu ofananira CAT5 kalasi. Mu mankhwala kumene adamulowetsa awiri zopotoka zolumikizira ntchito, zomwe molondola wachinsinsi monga 8P8C, koma pali dzina zosavomerezeka iwo - RJ-45. Mwina kudziŵika kuti zingwe lolingana osachepera kalasi CAT5 ndi CAT6, angathe kupatsira deta imathamanga pafupi pazipita kwa zomangamanga mtundu - mpaka 1 Gbit / s.

CHIKWANGWANI kuwala

Mwina kwambiri masiku ano ndi kusala zingwe kompyuta zopezera - CHIKWANGWANI. Mu dongosolo lawo, panopa kuwala kalozera zinthu za galasi kuti kudziteteza olimba kutchinjiriza pulasitiki. Mwa ubwino chifungulo cha zingwe deta maukonde anu kompyuta - chitetezo chokwanira mkulu kusokonezedwa. Komanso kupyolera CHIKWANGWANI akhoza kusamutsa deta pa mtunda wa pafupi 100 Km. A pawiri wa mtundu uwu ndi zipangizo chingwe angathe kuchitidwa ndi mitundu yosiyanasiyana ya zolumikizira. Pakati ambiri - SC, FC, F-3000.

Kodi izi moni-chatekinoloje maukonde chingwe kuti kompyuta? Photo CHIKWANGWANI chamawonedwe mapulani pansipa.
