Yintoni a kwinethiwekhi yekhompyutha

Nangona ukuba kwiminyaka yakutshanje, uthungelwano lwekhompyutha asetyenziswa ehlabathini lonke, maxa wambi abantu kunzima ukuqonda intsingiselo, emi kule kota. Le meko kakhulu eqhelekileyo kuphela technology computer. Kulo mzekelo, igama elikhulu Uyayifihla ixhaphake kakhulu kubo bonke kwinethiwekhi eyaziwa ikhompyutha.

networks computer basoloko bexakaniseka kunye neenkqubo ukuze computing ezisasaziweyo. Intsingiselo yomsebenzi wabo kuxhomekeke isibakala sokuba umnini-computer ukufakwa isebenza kwi inkqubo client ekhethekileyo. Ngokungqinelana elidityanisiweyo (umzekelo reactions zenyukliya, uphando lwezonyango) idle computing power kulayishwa umsebenzi, isiphumo ethunyelwa ku kumncedisi wobekelo kude. Kubalulekile ukuba ikhompyutha yakho hayi ulindele ngokupheleleyo yonke le ngxaki, yaye inxalenye yayo. Ukubala aseleyo yahlulwa phakathi umqalisi engundoqo kunye namanye amalungu inkqubo computing. Umzekelo odumileyo - Folder & Home. Igama elithi "inethiwekhi esuka kwikhompyutha" kunye bamathidala zingasetyenziswa iiprojekthi ezinjalo. Kwelinye icala, eli gama nangoku ngokuqhelekileyo ndaqonda okuninzi kancinci.

uthungelwano computer inkqubo wonxibelelwano nawuphi na izixhobo zekhompyutha. Ngoko ke, computers ezimbini eziqhagamshelene womnatha, akukho mfuneko yokuba ukudlulisela ulwazi naziphi isekela eliphakathi. Ukusebenzisa yangoku modulated zombane sasiphathwa wire; ukukhanya ifayibha-optic cable okanye kukho mhlaba otsalayo kwimeko uhlobo lonxibelelwano engenazingcingo, kunokwenzeka ukuba ukusombulula ingxaki leyo kakuhle kakhulu ngakumbi bi-owenza transfer data.

Ukwakha inethiwekhi luqala kwenkcazo kwisangqa wemisebenzi. Ukuba nje ufuna ukudibanisa izixhobo computing ezininzi eliphethwe ngumsebenzisi efanayo, njengoko umthetho, oko isekethi elula kakhulu. Loo network kuthiwa PAN (Eng. Area Network Personal). uthungelwano ukwanda kakhulu local (LAN). Bona luphawulwa iziseko evaliweyo closed, leyo bayavunyelwa ukuba kukho kuphela inani eliqingqiweyo abasebenzisi. Ukufikelela ezinye iinethiwekhi ngokuqhelekileyo bani konke konke. Umzekelo iiklabhu computer, apho bonke matshini ezidibene nge LAN; ofisi ezahlukeneyo (kuquka uhlobo kunye izakhiwo ngamnye), apho iikhompyutha ezininzi ezisetyenziswayo ngaxeshanye yaye njalo njalo.

Ukudala uthungelwano sobulali singamiswa engenziwa ngumsebenzisi kunye nolwazi kuphela olusisiseko sifundo. Yiloo nto eyabangela ubunzima "Lokaloka" othandwa kakhulu ngamaxesha ukufikelela ingafikeleleki okanye imali eninzi kwi-Internet ehlabathini. Ngoko ke, esebenzisa isibini ephothiweyo okanye intambo yafakwa nge ntliziyo wajoyina iqela iikhompyutha ngaphakathi kwisakhiwo esasakhiwe. Loo inethiwekhi kufuneka kwandiswa ngokuthi ukuhlanganisa ulwazi kunye nezindlu LAN eselumelwaneni. Bona kusonjululwa ezininzi iingxaki kwaoko: ukutshintshiselana ngolwazi, ukuze ndithethe, ngaphandle zokumka ekhaya, kwakunye kuvunyelwa ukuba basebenzise iinkonzo umniki-sevisi ye-intanethi, kunye ukuhlawula imali yokukhwela.

Okwangoku, iindleko zeenkonzo ukufikelela kwinethiwekhi Internet jikelele (Eng. Area Network Wide, WAN) iye ezikhoyo, kwanomntu nge-avareji kwemivuzo, ngokunjalo nemfuneko kwezi networks local ikhaya ezininzi ngaphambili. Ngoku, angaphezu LAN kakhulu kudityaniswe izixhobo computing ngeendlela ezahlukeneyo nemibutho yoshishino, apho loo izisombululo ebezifunwa kakhulu. Umzekelo, ngokudibanisa iikhompyutha ezibini ariya yobulali yomsebenzi womnatha unako ukwabelana yabavavanyi, abashicileli njalo njalo. Ukuba okunene ithetha imali. Njengoko inani elikhulu koomatshini isiphumo kwezoqoqosho iqapheleka kakhulu ngakumbi.
