Mhando Computer Networks

Zvinozivikanwa kuti chimwe chinokosha kubudirira yokupedzisira remakore yaiva pakasikwa vanhu uye kukurumidza kukura mashoko michina - ruzivo, kushandisa makombiyuta uye-siyana kombiyuta network, chitoro, muitiro, exchange uye uchatamisa yakawanda mashoko. Zvinokosha kucherechedza kuti yakadaro nokukurumidza kusvetuka mashoko vanhu rava zvichibvira chete pashure kombiyuta kukurukurirana network zvakasikwa.

Ose kombiyuta network vari muunganidzwa makombiyuta akagoverwa pamusoro imwe nzvimbo uye interconnected ne specialized migero, vachibvumira kuti kushandisa mashoko. Nhasi network kombiyuta anoshandiswa nevakawanda,-siyana kombiyuta network kushanda munyika uye kushamwaridzana nemumwe. Modern kunzwisisa zviri network, zvakakonzera kupatsanura pakati miganhu musimboti. Maererano kupatsanura ichi zvinosanganisira mhando kombiyuta network dzakadaro:

Global Area Network (Gan) - pose richikurukura makombiyuta uye nomumbure riri munzvimbo dzakasiyana-siyana dzenyika.

Wide Area Network (Wan) - pamwero mukuru network kuti zvinobatana kombiyuta network pachiyero makondinendi uye nyika;

Metropolitan Area Network (MAN) - refu daro network makombiyuta uye network mukati kumatunhu nezvimwe administrative dzakabatana;

Local Area Network (Lan) - Lan, zvichiratidza kuti kusangana makombiyuta riri pfupi kure - Somuenzaniso, mukati chete chivakwa.

Wan uye MAN ndivo emunharaunda network. Zvinokosha kucherechedza kuti kune zuva, weboka kombiyuta network iri Wan uye MAN iri zvikuru zvimiso, sezvo zvino mumwe anenge remunharaunda rezvebonde zvaisanganisira chero pose network.

Masangano akawanda kuti vanofarira pakupa refu azvipire mashoko kudzivirira encroachments kubva kunze (somuenzaniso, mauto, mabhengi, etc.), nokusika network dzavo, aizivikanwa chepamusoro. Mune yemakambani rezvebonde kungasanganisira makumi ezviuru makombiyuta kuti dziri panguva yakawanda kure mumwe Somuenzaniso, munyika dzakasiyana.

Rakajairika munyika dziwande vari vemo network kombiyuta.

The chikuru chepfungwa zvingangoguma munzvimbo network kubatanidza makombiyuta waya pasina kushandisa mugero kuti mashoko yedzimudzangara, shandisa paupamhi nharaunda network (runhare network, internet optic wire, Nhepfenyuro yeredhiyo nezvakadaro.). Sezvo makombiyuta dziri pedyo nepedyo, kuti asike nomumbure kubatanidza zvakakwana waya yavo uye kuchinja maererano. Network makombiyuta ari kombiyuta pomumbure IPLs rinopa wayo yakawanda zvakanakira.

Mhando vomunharaunda network kombiyuta kazhinji vaudzewo topology - nzira unobva makombiyuta mumwe. The topology kunokosha hunhu omunzvimbo network, nokuti akatsunga nenzira mukomboni anokosha Nhamba akauya kuita uye kushanda rakavimbika.

The zvikuru mukana nemambure vakaita maererano topology kuti "nyeredzi" - mumwe huru kunobva zvakabatana ose dzimwe makombiyuta pamusoro pemambure.

Pane network, akaumba maererano topology ari "mhete" - makombiyuta zvose kukurukura nemumwe mu dzinotevedzana uye pakupedzisira anoumba chinhu chakatodzana mhete.

A chechitatu mhando topology, izvo zvakasikwa omunzvimbo network kombiyuta, bhazi topology - makombiyuta zvose vari chokuita chete waya - date bhazi.

Computer network, sei vanoshanda, protocols, uye Hardware zvinoriumba vari kuramba vari nani uye dzakabudirira.
