Yintoni a LAN?

Area Network Local - iqela iikhompyutha kwadityaniswa, ibekwe kwindawo ethile, ezifana sisakhiwo. Imilinganiselo uthungelwano enjalo nomahluko. Inokuba yenziwe of workstations ezimbini ibekwe kwigumbi elinye, ukuze workstations eziliqela ikhulu, apho ibekwe phezu imigangatho eyahlukeneyo kwisakhiwo solawulo. Kwiimeko ezininzi, umbutho lweekhompyutha uthungelwano zingasetyenziswa iintlobo ezahlukeneyo kweekhebhile. Noko ke, admissibility kunye nokusetyenziswa kwemijelo wireless, njengokuba nayo iya kuxoxwa. Ngoko ke, masikhe aqonde ntoni LAN? Kubalulekile ukuba uqaphele ukuba umsebenzi womnatha ushiya imida kwisakhiwo esinye, bekuya kuba echanekileyo ukubiza ehlabathini. Ngokubanzi, iincwadi ezikhethekileyo kokuba ugqibe ukuba umsebenzi womnatha wobulali lelona isakhiwo, nangenxa jikelele, akukho isithintelo enjalo.

Akusoloko definition uncwadi ekwafanekisa nesithethe, kuba ngokuqhelekileyo uthungelwano ixhomekeke obusebenzayo, kunokuba Iimpawu zomzimba. Ngale ndlela, leyo yeyona ixhaphakileyo, uthungelwano ezinjalo ziyindlela ukukhonkca PC, ebavumela ukuba bafumane hardware ezahlukeneyo. Oko kukuthi, ezi iikhompyutha ukufikelela kwizibonelelo kwinethiwekhi ezahlukeneyo, ezifana ingabashicileli, yabavavanyi, ngokungathi ufakwe ngokobulali. Ngokwendalo, phantsi ukufikelela kwi izixhobo kwaye wenzelwe ukufikelela data ekhoyo kule izixhobo.

Ngoko ke, umbuzo wokuba yintoni ariya yobulali yomsebenzi womnatha, sele kubonakala onke acacile. Noko ke, nalapha kukho bokuqonda ezininzi. Zonke computer womnatha nje kuphela nako ukufikelela amacandelo womnatha efakiweyo, kodwa ukuze bazisebenzise ngendlela efanayo kufakelo lwasekuhlaleni, nto leyo iquka ukuqaliswa yokwabelana data enyanzelekileyo.

Le ndawo yokuqala indawo network wacofa ofisi computer lokuqala isizukulwana - kweekhompyutha mainframe kwi womnatha, Noko ke, imoto lokuqala wasiwa ukufaka njengezixhobo ezahlukeneyo. Kufuneka athi malunga ndlela abangekaphuhli le womnatha wobulali xa umsebenzisi for data nokuzikhuphela ifloppy diski kwifowuni enye, uze emva koko wegqitha kwenye ukuprinta ulwazi okanye ukugcina nje apho. Esi sigqibo ayikwazi kuba yinto embi, ingakumbi xa ucinga ithuba bekhuphela imiqulu esikhulu solwazi. Kodwa apha, kananjalo, kukho iziphene, yaye kakhulu kunene;

- umngcipheko ukulahleka kwengcaciso kwimeko yelahleko okanye ingozi ufomatha data laliphezulu kakhulu;

- kuvela Ubunzima kunye ungqamaniso iinguqulelo ezahlukileyo loxwebhu xa kuyimfuneko ukusebenza nangaphezulu komntu omnye ngexesha;

- ubukhulu yediski ebhetyebhetye yi 1,44 MB kuphela, kwaye ubungakanani ifayile yeenkcukacha efunekayo kudodobalise kugqithisela;

- lulungiselele abasebenzisi ukwenza umsebenzi amaxwebhu usebenzisa izicelo ezahlukeneyo pre-kufakwa ezikhompuyutheni;

- idatha kwakunzima ukukhusela njengoko yediski ebhetyebhetye kufuneka nje ibiwe;

- bachitha ixesha elininzi kwinkqubo njengokukhuphela iifayile, ukutshintshela ukuba omnye umatshini, ngokunjalo nemisebenzi ezilandelayo kuyo.

Yiyo loo nto loo iinethiwekhi ifanele kuphela zokusombulula imisebenzi kwakudala. Ngoko ke, yintoni na womnatha wobulali kule ngqiqo? izibonelelo-ofisi mihla kufuneka ihlangabezane neemfuno ezintsha:

- ukwabelana, ukukhuselwa kunye nokusasazwa data;

- izicelo kufuneka zifikeleleke ukuba kwabelwane;

- abasebenzisi kufuneka kube lula ukunxibelelana nabanye;

- izixhobo neuropathy kufuneka zenziwe zifumaneke kuzo zonke koomatshini.

Ngoku uyazi nje kuphela yintoni na indawo womnatha wobulali, kodwa yintoni na imigaqo ebekwe phantsi isisekelo salo.
