I-iMacs ka-2011 iyisinqumo esithandwayo kulabo abafuna i-iMac esetshenzisiwe nazo zonke izintandokazi.2011 babone ukuthuthukiswa okuningi kwe-iMac, ngenkathi begcina izinga eliphezulu lokukhulisa okwenza ukuba babe ngabafundi abafanelekile ngokwezifiso. Eminyakeni eyalandela yabona okunye okukhethwa kukho okufana nokusebenzisa i-RAM engaqondakali emgwaqeni egameni lezindleko zokunciphisa izindleko. Kwakungumnyaka wokugcina we- CD / DVD drive eyasuswa ukuze kuvunyelwe umklamo omncane owethulwe ngamamodeli ka-2012.
Uma ngabe unesithakazelo ekuqoqeni i-iMac esetshenzisiwe ka-2011, funda ukuze uthole ukuthola nokuphuma kwamamodeli kaMac 2011.
I-iMacs ye-2011 iye yathola enye inguquko eguquguqukayo. Kule nkathi, i- iMacs ifakwe amaprocessors we-Quad-Core Intel i5 noma i-Quad-Core Intel i7. Ngcono nakakhulu, amaprosesa ka-2011 asekelwe kwisihlalo sesibili se-Core-i, esivame ukubizwa ngegama layo lekhodi, iSandy Bridge.
I-iMacs iphinde ithole ihluzo ezibuyekeziwe kusukela ku-AMD, nechweba le-Thunderbolt, eliletha ukuxhuma okuphezulu kakhulu kwi-iMac.
Ngenkathi i-iMacs ka-2011 ingcono kakhulu iMacs Apple ikhiqize, kubalulekile ukukhumbula ukuthi noma iyiphi ikhompyutha yedeskithophu yonke idinga ama-tradeoffs ambalwa. Ngakho-ke, masihlole futhi sibone ukuthi i-iMac ye-2011 izohlangabezana nezidingo zakho.
Ukwandiswa kweMac
Umklamo we-iMac unciphisa uhlobo lokuthuthukiswa umnikazi angakwenza, okungenani ngemuva kokuthenga. Lokhu akuyona into embi; i-compact design ineziningi zezici eziningi kubasebenzisi bamaDeskithophu abazoke badinga.
I-iMac iyinhle kakhulu kulabo abachitha isikhathi sabo basebenze ngezinhlelo zokusebenza, futhi abafuni ukuchitha amandla okuzama ukulungisa i-hardware ukugoba ngentando yabo. Lokhu kuhlukaniswa okubalulekile, ikakhulukazi uma ujabulela ukuhambelana ne-hardware ngaphezu kwakho. Kodwa uma ufuna nje ukwenza umsebenzi ufeze (futhi ujabule kancane), i-iMac ingaletha.

I-RAM enwetshiwe
Indawo eyodwa lapho i-iMac ikhanya khona ekunwetsheni komsebenzisi i-RAM. I-iMacs ye-2011 inikeza izinkomba ezine ze-SO-DIMM, ezimbili zazo ezinamamojula amancane we-2 GB RAM ekulungiseleleni okuzenzakalelayo. Ungakwazi ukwengeza kalula amamojuli amemori amabili, ngaphandle kokulahla i-RAM efakiwe.
I-Apple ithi i-iMac ye-2011 isekela okungenani u-8 GB we-RAM, futhi imodeli engu-27 intshi eyenzelwe iprosesa i7 isekela kufika ku-16 GB we-RAM. Ngokweqiniso, ukuhlolwa okwenziwe ngabathengisi be-RAM yangaphandle kubonisa ukuthi wonke amamodeli asekela kuze kufike ku-16 GB, futhi i7 kuya ku-32 GB.
Ukungafani kubangelwa ukuthi i-Apple yayinganiselwe ukuhlola i-iMac ka-2011 ngamamojula we-4 GB RAM, ubukhulu obukhulu obuvame ukutholakala ngaleso sikhathi. Amamojula ayisishiyagalombili we-GB manje atholakala ekucwangcisweni kwe-SO-DIMM.
Ungasebenzisa inzuzo yokwandisa i-RAM ngokuthenga i-iMac enokulinganisa okungenani okungenani kwe-RAM, nokwengeza amamojula wakho we-RAM. I-RAM ethengwe kusuka kumuntu wesithathu ivame ukuba engabizi kakhulu kune-RAM ethengwe ku-Apple, futhi ingxenye enkulu, ilingana nekhwalithi.
Isitoreji se-iMac sika-2011
Isitoreji sangaphakathi se-iMac asikwazi ukuthuthukiswa komsebenzisi, ngakho-ke kufanele wenze isinqumo mayelana nosayizi wesitoreji phezulu. Kokubili i-iMac engu-21.5-intshi ne-27-intshi ihlinzeka nge- hard drive ehlukahlukene kanye ne-SSD (okuyi-Solid State Drive) ongakhetha kukho. Kuye ngesibonelo, izinketho ezitholakalayo zifaka izinkomba ezinzima ze-500 GB, i-1 TB, noma i-2 TB ngesayizi. Ungakhetha futhi ukufaka esikhundleni se-hard drive nge-256 GB SSD , noma ulungise i-iMac yakho ukuthi ibe ne-hard drive yangaphakathi kanye ne-256 GB SSD.
Khumbula: Ngeke ukwazi ukushintsha kalula i-hard drive yangaphakathi kamuva, ngakho-ke khetha isayizi enkulu kakhulu ongayithola.
Ukubonisa Okuhle
Uma kuziwa ekubonisweni kwe-iMac, kunkulu yini kangcono njalo? Ngimi impendulo inguyebo, yebo, yebo. Umbukiso we-iMac wamasentimitha angu-27 umane umangalisa ukusebenza nawo, kodwa, mfana, kuthatha indawo enkulu yedeskithophu yangempela.
Uma ufuna ukulondoloza isikhala, i-iMac engu-21.5-intshi ikufakile. Zombili izibukeli zeMac zenza kahle, zisebenzisa amapaneli e-IPS LCD ne-LED ukukhanyisa. Le nhlanganisela inikeza i-angle ebanzi yokubukwa, ububanzi obukhulu obuhlukile, nobuqotho obuhle bombala.
I-iMac engu-21.5-intshi inesinqumo sokubuka sika-1920x1080, esizokuvumela ukuthi ubuke okuqukethwe kwe-HD ngendlela yobuqiniso obuyi-16x9. I-iMac engu-27 intshi igcina ububanzi obuyi-16x9, kodwa inesinqumo esingu-2560x1440
Okuwukuphela kwendlela engase ibe yinkinga ekubonisweni kwe-iMac ukuthi kuhlinzekwa kuphela ngokucushwa okuluhlaza; akukho ndlela yokubonisa i-matte etholakalayo. Ukuboniswa okwesibhakabhaka kuveza abamnyama abajulile kanye nemibala enamandla kakhulu, kepha ukukhanya kungaba yinkinga.
Ama-Graphics Processors
I-Apple igxile iMacs ka-2011 enezinhlu ze-graphics ze-AMD. I-iMac engu-21.5-intshi isebenzisa i-AMD HD 6750M noma i-AMD HD 6770M; kokubili kufaka i-RAM engu-512 MB yehluzo ze-RAM. I-iMac yama-27 intshi inikeza i-AMD HD 6770M noma i-AMD HD 6970M, ne-1 GB yamahluzo we-RAM. Uma ukhetha i-iMac engu-27 intshi neprojector ye-i7, i-RAM ihluzo ingalungiswa nge-2 GB.
I-6750M esetshenziswe kuMacac 21.5-intshi iMac ngumculi omuhle kakhulu, ngokushaya kalula ukusebenza komprosesa we-4670 wonyaka odlule. I-6770 inikeza ukusebenza kwehluzo okungcono nakakhulu, futhi cishe kuyoba yinkqubo yegrase ethandwa kakhulu ngo-2011 iMacs. Ungumdlali omkhulu ohamba phambili, futhi kufanele ahlangabezane kalula nezidingo zezingcweti zegrafu, kanye nalabo abajabulela imidlalo embalwa ngezikhathi ezithile.
Uma ufuna ukucindezela ukusebenza kwehluzo, kufanele ucabange ngo-6970.
Izinketho Zezinqubo ze-iMac
I-iMacs yango-2011 isebenzisa i-Quad-Core Intel i5 noma i-processors ye-i7 esekelwe kwisakhiwo se-Sandy Bridge. Akusekho amaprosesa ase-i3 asekelwe esizukulwaneni esidlule. Ama-iMacs angu-21,5-intshi anikezwa nge-2.5 GHz noma 2.7 GHz i5 prosesa; i-2.8 GHz i7 iyatholakala njengokhetho lokuzakhela. I-iMac yama-27 intshi iyatholakala nge-2.7 GHz noma i-proxy 3.1 GHz i5, ene-3.4 GHz i7 etholakala kumodeli wokwakha ukwakha.
Bonke abaprosesa basekela i-Turbo Boost, okwandisa isivinini seprosesa lapho kusetshenziselwa ingqikithi eyodwa. Amamodeli we-i7 nawo anikela nge-Hyper-Threading, ikhono lokusebenzisa imicu emibili engxenyeni eyodwa. Lokhu kungenza i-i7 ibonakale njengeprosesa eyisi-8 efonini yakho ye-Mac. Ngeke ubone ukusebenza okungaphakathi kwe-8, noma kunjalo; Kunalokho, into ephakathi kwama-5 no-6 ama-cores ingokoqobo ekusebenzeni kwezwe langempela.
Thunderbolt
I-iMacs ka-2011 yonke ine- Thunderbolt I / O. I-Thunderbolt iyinhlangano ejwayelekile yokuxhuma izithako kwi-iMac. Inzuzo enkulu enkulu ijubane; iphuma ngaphandle kwe-USB 2 nge-20x, futhi ingasetshenziselwa ukuxhumana kwedatha nevidiyo, ngesikhathi esifanayo.
I-Port Thunderbolt kwi-iMac ingasetshenziswa nje kuphela njengendlela yokuxhumana yangaphandle, kodwa futhi njengedatha yedatha yokuxhumana yendawo. Okwamanje, kunamadivaysi ambalwa kuphela atholakalayo, ikakhulukazi ama-RAID angaphandle okufakwe ngaphakathi, kodwa iMakethe yezinto ezibonakalayo ezibhekene nokuduma kufanele ibone ukuthuthukiswa okukhulu ehlobo lika-2011.
