LVS - a mabikirwo chipo

Pari guru kwazvo kwakapararira kombiyuta network. Navo vanokwanisa kushanda pamwe chete zvinhu, zvirongwa, data, zvakananga kubva yavo workstation.

Chii chinonzi Lan?

Vakawanda mhando network - yemo nzvimbo network.

LVS - kombiyuta Network unobva yomunharaunda muchina vanoshandisa vari chinhambwe kubva mumwe. Kunyange kuwanda pomumbure kusvikira wandei makiromita, kakawanda kushandiswa kubatana makombiyuta ari kure duku. Kazhinji, nokushanda uyu muchina mumwe zvebhizimisi kana musha hrs.

configuration pamusoro Lan

Configuration inogona kutaurwa LANs uye Server kuzvidzora pasina (zvakaenzana).

Nyatsotarira vemunzvimbo samambure

In network dzakadaro, makombiyuta zvose akafanana tichitaura nokurondedzerwa. Nyatsotarira-to-Lan - yomunzvimbo samambure umo mumwe workstation anogona kuita zvose zvinowanika mashandiro anoita zvose nemhosva uye Server. For vakarongeka mutoro BALANCInG mune nhamba pokuita kombiyuta Lan haangavi anopfuura 10. Zvimwe, yose zvakarukwa waivako anotambura.

Network kutarisirwa Server (multilevel)

In akadaro Lan mumwe makombiyuta ari kuita zvakasiyana nani, ndangariro vanokwanisa, uye zvimwe zviratidzo. PC Izvi basa ne Server. Servers pamusoro Lan - ndivo makombiyuta dzakakwirira kuita uye guru ndangariro vanokwanisa kufananidzwa rokushandisa vemo muchina. Ndiye anopa inowanikwa kune dzimwe makombiyuta pamusoro pomumbure, zvitoro uye anoronga ruzhinji mafaira kuwana kwavari, transmits humboo kusvika yeGmail.END_STRONG muchimiro ruzivo kuti ribude kana kuguma mugumisiro. Lan, umo Server chete kushandiswa kutakura zvakajairika data, inonzi network ine akazvitsaurira faira Server. Pamwe izvozvo gadziriro, pane Lan, umo Server chiri kuitwa uye kubudiswa ruzivo, uye nemhosva anogamuchira chete mugumisiro. Izvi zvinonzi yeGmail.END_STRONG-Server enyika.

Lan topology

makombiyuta All pamusoro pomumbure panguva mumuviri pamwero vari interconnected. Lan topology - nzira kubatanidza yomunharaunda muchina. Zvino LANs yeimwe anoshandiswa nzira dzakadai bhazi, nyeredzi, uye mhete.

bhazi topology

Mune Lan, iyo kereke akaronga maererano ichi topology rinoshandiswa paungano imwe waya, vakabatana zveko kombiyuta user. Saka, mashoko ari mumwe muchina anoenda kuburikidza vamwe vose. The workstation, izvo yakanyorerwa data, anosarudza zvandinenge mashoko kubva rwevanhu rukova.

Zvakanakira bhazi topology Lan:

• mumwe atadze kushanda zvakanaka imwe vemo makombiyuta hakumbokanganisi kushanda nevamwe michina uye network zvavo;
• munhu zviri nyore kunzwisisa configuration uye pamasikiro Lan;
• vade yakaderera mari consumables (ane diki nharaunda kuita Somuenzaniso, mukati chete sangano).

Payakaipira topology:

• Cable kukuvara chakavhara samambure zvavo;
• shoma siyana uye vanoshandisa shoma;
• mumwe nokukurumidza zviduku (zvichienderana nokuwanda makombiyuta pamusoro pemambure).

"Nyeredzi" topology

The topology iri mhando kunosanganisira kubata vomunharaunda makombiyuta Via Network midziyo (nomusimboti kana nomusimboti) kuti anopa yakafanana kubatana yokushanda michina. chiteshi Mumwe zvakabatana hondo mudziyo kuburikidza yoga waya Network kadhi. Sezvo muzvirevo muchimiro topology, zvekubuda mashoko anowanikwa pamakombiyuta zvose pamusoro pomumbure, uye zvichaita chete kugamuchirwa inodzidzisa ravakanga vari chinangwa.

Benefits topology:

• shungu kuronga basa idzva;
• mukuru kunyatsoshanda;
• Kutsanya mhosva kana waya kumbozorora;
• pamusoro nokushanda nemambure regai kukanganisa mhosva vomunharaunda michina nomumwe.

Payakaipira topology:

• kukundikana chikuru chikwata rinomira oparesheni yose samambure;
• nhamba vanoshandisa kurambidzwa nhamba zvengarava zviri nechepakati chikwata;
• uneconomical kunwa mu waya;
• kutora mari Hub (kana zvimwe zvinoshandiswa Network).

Topology "mhete"

Lan kugadzwa yakaitwa maererano nemitemo iyi mhando topology, ine akatevedzana interconnected kushanda michina wezvamatongerwe rin'i. The Data muchiitiko ichi vari kubva kombiyuta imwe neimwe, uye vanogara chokwadi kuti vari kutaurwa.

Advantages topology "mhete":

• Hapana mari pamumbure midziyo (nomusimboti, router);
• kukwanisa kubvisa mashoko pakati makombiyuta akawanda panguva imwe chete.

Payakaipira topology:

• chokupika yose rezvebonde ichitovimbawo kumhanya neimwe kombiyuta;
• Kukurira waya kana kukundikana kombiyuta imwe yavharwa mashandiro panyika nemambure;
• kunzwisisa kwakaita setup uye configuration;
• The sangano mabasa matsva panguva remadza basa Lan.

The topology of "ring" iri zvinenge harimboshandiswi mune tsika nokuda vakawanda kuchengeteka, asi zviri pasi okunatsiridza siyana.

Pari, zvokuti hapana sangano kuita pasina Lan. More zvakafanana "nyeredzi" zvakarukwa topology nokuda akavimbika dzavo uye mhosva shiviriro. Lan topology "mhete" Kusiyana neizvi, regai kusangana ano utano uye vakachengeteka zviratidzo. Zvisinei, Lan yose vava chikamu hwedu uye zvinobatsira kubudirira chero vachida.
