Software Network: umbutho ka yentshukumo zayo yonke

software Network ngokuqinileyo kubomi indoda kwinkulungwane yama-21. Ngawaphi amathuba inika abasebenzisi zesiqhelo? Njani na umbutho yentsebenziswano phakathi kwabantu ezahlukeneyo? Ziziphi izixhobo isetyenziselwa le njongo? Nalu uluhlu buso imiba ekufuneka iqwalaselwe kwinqaku.

amathuba

Yintoni le software womnatha ngokwemiqathango kwintlangano yentshukumo zayo? Yonke ngexesha elinye, kwaye ayinakuchazwa. Okokuqala, makhe siqwalasele ngamathuba nokwabelana ngolwazi in networks zehlabathi kunye lendawo:

1. E-mail.
2. Amaqela eendaba.
3. Ukuncokola phezu Internet.
4. Teleconference.
5. Newsletter.
6. izixhobo zonxibelelwano-time real (leyo angathumela umbhalo, isandi kunye nemifanekiso), kwakunye ukusebenzisana kunye nezinye izicelo.
7. Skype.

Konke oku kusetyenziswa ukuze aqhube ebhalelwa, ukusebenza kunye neencwadi ezinika ingcaciso, ukuthumela i data ithumele iifayile eziyimfuneko azise iindaba.

indlela ayisebenzisayo

Ethetha ithuba software network sokucwangcisa yentshukumo zayo, kuyimfuneko ukuba banikele ingqalelo kule software kusetyenziswa. Ngoko ke, ngokuba unxibelelwano phezu Internet indima ebalulekileyo kufuneka abancedisi. Ngoko-ebizwa inkqubo ezikhethekileyo athumele imiyalezo phakathi yeposi isikhokhelo ngayo. Qamba, ukuthumela ukubonisa ukuba umsebenzisi yenza client e-mail. Kusenokwenzeka kusebenza kwakhona iqonga networking lokuququzelela yentshukumo zayo yonke, leyo eziququzelelweyo ukuze baxoxe kwaye iindaba Ukutshintshana indlela ethile. Kuba Iintlanganiso ezingxamisekileyo Ungasebenzisa ividiyo neenkomfa. Banceda ukuba alungiselele iintlobo software ezahlukeneyo. Eyona idumileyo - Skype kunye Raidcall. konke oku Kodwa - kuphela imisebenzi kumphezulu. Ngoko ke, iinkampani ezinkulu abanomdla wokuqalisa uthungelwano zabo esekuhlaleni. Kwaye Ukongeza afanelekileyo - ilinki eyahlukileyo. Ngoko ke ingqalelo kwiimpawu zobugcisa ukuphunyezwa izinto ezinjalo.

Yintoni na le software network?

Oku sokwandiswa ebalulekileyo kulo naliphi na ishishini. Ukuba nokwenzeka software networking ukuvumela ukuba ukunika ufikelelo ekwabelwana kwinethiwekhi ulwazi yenkampani kunye nezibonelelo ikhompyutha, ukwabiwa dynamically ukuba ukunyusa isantya lweenkcukacha kwaye ukulayisha ubuhle hardware. Kucingwa nesimilo ukuba isicwangciso ukusabela xa ukusilela kweeyunithi ngamnye. Ukuzoba isifaniso, uyakwazi ukucinga kolu qweqwe lomhlaba. Umbutho le software network kukuba yinxalenye yomsebenzi kwinqanaba eliphezulu, yaye enye igxininisa iintsimbi. Kodwa lisebenzisana xa iyonke. Kulo mzekelo, uyakwazi ukubona ezi ndidi zilandelayo software:

1. software Iyonke. Omnye ufumana izicelo ezisisiseko iikhompyutha ngamnye ukuba yinxalenye yothungelwano.
2. software Special. Izicelo wadala izicelo ezibonisa ngqo kwisifundo kumsebenzisi xa kuqaliswa ingxaki yolawulo.
3. System networking software. Ngaba ngothotho lwezixhobo ezixhasa nokulungelelanisa zonke izibonelelo kwinethiwekhi yekhompyutha njengenkqubo enye.

Iindlela zokusebenza

Ngokuqhelekileyo, zibandakanya software inoxanduva lokuphunyezwa imisebenzi esisiseko ye computer. Kuthungelwano, bakhonza njengesiseko lombutho kokusingqongileyo msebenzi ezidityanelweyo. Ngenxa yoko, le yokusebenza nkqubo ngenxa amacandelo yayo ukunikeza:

1. ukufikelela Inter-nkqubo. Kulo mzekelo, oko kuthetha ithuba yokulungelelanisa ubudlelwane phakathi abandwendweli ezahlukeneyo isicelo ukuba ziyaphunyezwa kwiindawo ezahlukeneyo network.
2. Isicelo-esikhankanya Unikezelo (ukusuka kwindawo somsebenzisi lwembono, okokuqala zonke libhekisela I / isixhobo O).
3. Ukulingelelanisa software ezahlukeneyo.
4. Kwabelwana ngolwazi.
5. imiyalelo Kusetyenziswa evela terminal, leyo sazisa umqhubi.
6. Ukwabelana iseti data phakathi iikhompyutha ezahlukeneyo eqhagamshelwe kwinethiwekhi efanayo.
7. entry umsebenzi ekude (ukuba ufuna ukusebenza kwindawo esemagqagaleni esibulalayo).
8. Ukufikelela data ezigcinwe kwezinye iikhompyutha, kunye nokukwazi ukwenza kubo.
9. ukhuselo Data kunye nezibonelelo yothungelwano ezivela kubantu besithathu.

Le nkampani kwenkqubo yokusebenza kubasebenzisi

OS lula kakhulu umsebenzi womntu. Ngoko ke, wabulela kubo,

1. Ungakwazi ukuseta ukulandelelana izisombululo kwiingxaki ezikhoyo.
2. ukusebenza kwezibonelelo ezilawulwa network (hardware ne-software).
3. Imisebenzi kunikwa ingcaciso eyimfuneko, apho agcinwe kwiindawo ezahlukeneyo network.
4. Ukusebenzisa ulwabiwo zokusebenza izicwangciso kwezibonelelo, kuxhomekeke kwiimfuno ngalo mzuzu na abasebenzisi.

Amanqaku imisebenzi OS

Ukuba nokwenzeka software olungagcinwanga kwimibutho kufuna utshintsho olwenziwayo kunye neendlela ezithile umsebenzi. Ngoko ke, kufuneka uthathe unonophelo ixesha nolandelelwano ulwazi ababhalisele, ukusasazwa uluhlu lwemisebenzi phakathi zonke iikhompyutha kumsebenzi womnatha wakho, aze awanike inqanaba ephambili ukuphunyezwa kunye, xa kukho imfuneko, ukutshintsha uqwalaselo kwi computer. ulawulo zoMsebenzi ikuvumela ukuba ukufumana ulwazi inkqubo malunga nemvelaphi kunye nenjongo iinkqubo, ukwenza imisebenzi eyimfuneko aqokelele idatha. Kulo mzekelo, indlela yokusebenza uba dispatcher. Oku kulandela ukuvulwa iifayile yokuvala, ulawulo kusetyenziswa inkumbulo lisebenza kwaye ikhusela inkqubo yabo.

amathuba networking

Lo ngomnye weyona misebenzi ibaluleke gqitha yenkqubo yokusebenza. iindlela ezimbini iikhompyutha zenkxaso iimpawu ukuthetha omnye komnye. Eyokuqala ibandakanya unikezelo kwezibonelelo womnatha ukuthetha OS yakuma wedwa. Indlela yesibini kukuba ebusweni babo njengenxalenye yenkqubo yokusebenza ngokwalo (ifumaneka ixhaphake kakhulu kwihlabathi lanamhlanje). Kwakhona kufanele kuphawulwe ukuba OS kufuneka imisebenzi womnatha ezimbini: iseva kunye client. Osahluleyo kungenxa umahluko iingxaki ezijongene kwabo, owenza izixhobo womnatha. Network Uhlobo server software zangathi ziziikopi zezo ukulawula izibonelelo. A client ikwabonelela iinkonzo iimfuno umnini wayo ngempumelelo enkulu nesantya. Kuyimfuneko ukunikela ingqalelo ngenxa iqonga apho isebenza-software, kwakunye neempawu zawo.

Isantya kwaye multi-seHTML

kufuneka ibe yintoni software network? Umbutho lwemisebenzi ezidityanelweyo inzuzo kuphela sisebenza ngeqondo yona aphezulu kunokwenzeka. ukubaluleka kule nto multithreading. Undoqo kule nkqubo inzima kakhulu, kodwa nayo ubuso bakhe. Ngoko ke, kukho isilawuli ukuba usebenza ngesantya esiphezulu, kulinganiswa ngeeyunithi ezincinane ixesha - ngomzuzwana. Basuke ababulawa nokuba kukho eminye imisebenzi. Ngoko ke, lo iprosesa rhoqo idles. Ukunciphisa ezinjalo, ifowuni ichonga ngamnye amacandelo eziliqela ebandakanyeka kwiinkalo ezithile amanyathelo. Ngokuguqula ubungakanani yabo kuchaphazela inkalo esemgangathweni weqela umsebenzi. Ngokomzekelo, ingxelo, umzekelo, kufuneka rhoqo wafumana data ukusuka kuthungelwano lwezibonelelo ezikhoyo kunye neemveliso ugqibile. Nangona abasebenzi inkxaso karhulumente kufuneka ukufikelela kuyo ngaphandle ukulungiselela iingxelo zenkqubela.

kwabelwana ngolwazi

Ukwenzela ukuba abasebenzisi ukusebenza ngempumelelo, kufuneka ucinge umgangatho networking software (ngokungasilibali izixhobo). Umzekelo, ukuba ufikelelo kude data lweshishini elo, uyakwazi ukuqwalasela modem yakho esebenzisa ngayo lo msebenzi uya kwenziwa, ngokungathi ezindongeni nkampani. Umda kuphela lwedatha kwemiqathango kancinci. Kwakhona, ukwabiwa kwamanqanaba ukufikelela uyakwazi ukusebenzisa izixhobo ngokusebenzisana. Baya kuba luncedo ukuze alungiselele uququzelelo iinguqulelo lwamaxwebhu apho abasebenzisi abaninzi. Not ononyawo kwaye ugcine izimamva ixesha zokuqwalasela agcinwe kwi server womnatha, enye ikhompyutha okanye efini. Kodwa kuyimfuneko ukulawula emgangathweni kunaniselwano data. Oku kuya kunciphisa kakhulu umngcipheko iimpazamo, ngokunjalo abe nempembelelo entle isantya ekudluliseni iipakethi ngcaciso kwi-network.
