Impela ulibonile igama elithi 'inkumbulo yenqolobane' izikhathi ezingaphezu kwesisodwa, mhlawumbe ngenkathi ufunda ngendlela yokuthuthukisa ukusebenza kweselula noma ikhompuyutha yakho. Lona umqondo ohlobene eduze nezinto eziningi zedijithali esizisebenzisa nsuku zonke. Kule post siyachaza ithini inqolobane futhi ingeyani, ungayihlanza kanjani kumaselula namakhompyutha e-Windows futhi yiziphi izinzuzo zokwenza kanjalo.
Imemori yenqolobane iwumthombo obalulekile wezinhlelo zokusebenza nezinhlelo ukuthi zisebenze ngokushesha kunoma iyiphi i-CPU. Amadivaysi eselula namakhompyutha analolu hlobo lwememori yesigcinalwazi, kanye neziphequluli zewebhu. Njengezinye izindawo zokugcina, ngokuvamile kuwumqondo omuhle ukusula inqolobane njalo ukuze isebenze kahle.
Iyini inqolobane futhi ingeyani?
Kukhompyutha, inkulumo ethi 'cache memory' ibhekisela esisetshenziswa i-Central Processing Unit (CPU) okufanele iyisebenzise. gcina okwesikhashana idatha esanda kucutshungulwa kumemori eyisiza. Yaziwa nangokuthi inkumbulo yokufinyelela okusheshayo, njengoba igijima ngokushesha kunenkumbulo eyinhloko ye-CPU futhi yenza kube lula ukufinyelela idatha esanda kucutshungulwa.
Inkumbulo yenqolobane iyinkumbulo ephakathi phakathi kwe-CPU ne-RAM (Inkumbulo Yokufinyelela Engahleliwe), esebenzela ukuzuza isikhathi nokulondoloza izinsiza lapho kucutshungulwa idatha. Ngamanye amazwi, le nsiza kunciphisa isikhathi sokufinyelela kudatha ebalulekile futhi igwema ukuphindaphinda kwezinqubo ukwandisa isikhathi sokuphendula sesisetshenziswa.
Phakathi kwe idatha ebalulekile evame ukugcinwa kunqolobane ukunciphisa isikhathi sokufinyelela yilezi:
- Idatha esetshenziswa njalo okungaba ukuchitha isikhathi ukuyilayisha uma ihlale ilayishwa ukusuka kumemori enensa kakhulu.
- Idatha eyinkimbinkimbi ukuyikhiqiza, ngenxa yokuthi idinga inqubo yokubala ejulile noma ukuhlanganiswa kwayo okwenziwa emithonjeni ehlukene.
- Idatha okufanele isetshenziswe ndawonye futhi ngaleyo ndlela igcinwe ukuze igweme ukuyilayisha ngayinye ngayinye.
Izinhlobo ze-cache
Kunezinhlobo eziningana zama-cache, kodwa ngokuvamile sijwayelene kakhulu nezimbili ikakhulukazi:
- inqolobane yediski, okuyingxenye encane yenkumbulo ye-RAM ehlotshaniswa ne-hard drive yokugcina idatha esanda kusetshenziswa. Lokhu kuvumela ukuqalisa nokusebenza kahle kwezinhlelo ezifakiwe nezinhlelo zokusebenza.
- inqolobane yewebhu, isikhala esibonakalayo esikhona kuziphequluli zewebhu ukuze sigcine idatha yamakhasi esisanda kuwavula. Uma sivala ikhasi bese silivula futhi, sizobona ukuthi kuthatha isikhathi esincane ukulayisha. Lokhu kungenxa yokuthi idatha edingekayo yokulayisha ibhekwa kunqolobane, hhayi kuseva.
Isebenza kanjani inqolobane?
Ukusebenza kwe-cache kulula kakhulu: igcina idatha esanda kucutshungulwa ukuze inikeze ukufinyelela okusheshayo kuyo futhi ngaleyo ndlela yonge isikhathi nezinsiza. Ake sinikeze isibonelo ukuze sikuqonde kangcono:
Uma sisesha i-inthanethi noma sizama ukuvula uhlelo lokusebenza kukhompuyutha noma iselula, isisetshenziswa siyacelwa ohlelweni. Okusho ukuthi, sicela ithimba ukuthi lenze isenzo ngedatha ethile.
Ngenxa yalokho, isistimu ibheka idatha kunqolobane noma imemori yokufinyelela ngokushesha ukuze yonge isikhathi; uma zikhona, isenzo esiceliwe senziwa ngokushesha, okwaziwa ngokuthi i-cache hit noma i-cache hit.
Kunalokho, uma insiza eceliwe ingekho kuyo, idatha ilayishwa isuka kusistimu engaphansi (i-RAM noma iseva), edla isikhathi esiningi nezinsiza (i-cache miss noma i-cache miss). Le datha igcinwa kunqolobane ukuze uma iphinda iceliwe ngokuzayo, izotholwa lapho.
Sula inqolobane: kungani kudingekile?
Kusobala ukuthi ukusetshenziswa kwenkumbulo yenqolobane emishinini yesimanje ehlukene kagesi kubalulekile ukuze kuthuthukiswe ukusebenza kwayo. Ngenxa yale nkumbulo yesikhashana yokufinyelela okusheshayo, amakhompyutha namadivayisi eselula athatha isikhathi esincane ukuphendula futhi asebenze ngokuphumelelayo. Izikhathi zokulayisha ziyafinyezwa futhi izinsiza ezidingekayo ukuze kuqhutshwe izinqubo ziyagcinwa.
Kodwa-ke, njengoba inkumbulo yenqolobane inesikhala sokugcina esilinganiselwe (okuvame ukungesikhulu kakhulu), kuvamile ukuthi igcwale ngokuhamba kwesikhathi. Ngalesi sizathu, iphrosesa yekhompuyutha ngokwayo yenza inqubo evamile yokususa ngaphandle kokuthi ukungenelela kwethu kudingeke. Nokho, ngezinye izikhathi kuyadingeka sebenzisa ukusula inqolobane ngesandla ukuze uhlelo lukhulule isikhala.
Uyisula kanjani inqolobane yamadivayisi akho?
Uma sikhuluma ngememori ye-cache, akunakugwenywa ukuthi sizibuze ukuthi siyisusa kanjani idatha egcinwe kuyo. Uma ufuna ukwazi ukuthi ungayisusa kanjani i-cache yesiphequluli nezinhlelo zokusebenza kuselula yakho, ngena kokufakiwe uyisula kanjani inqolobane yeselula ukuze uvule isikhala. Ngakolunye uhlangothi, uma lokho okufunayo kuyinto khulula isikhala senqolobane kukhompuyutha yakho ye-Windows, landela imiyalo engezansi:
- Cindezela okhiye be-Windows + S ukuze uveze injini yokusesha yesistimu bese uthayipha i-Dick Cleanup, okuyithuluzi le-Windows lokukhulula isikhala sokulondoloza.
- Khetha ithuluzi bese ukhetha idrayivu ofuna ukukhulula isikhala kuyo.
- Bese, isistimu izokwenza ukuskena kwedrayivu ekhethiwe ukubala isikhala esingasulwa, kuhlanganise nedatha yenqolobane.
- Qinisekisa ofuna ukukususa bese uchofoza okuthi 'KULUNGILE'.
Yiziphi izinzuzo zokususa inqolobane?
Ukusula idatha egcinwe kunqolobane ngezikhathi ezithile kunenzuzo ngenxa yezizathu ezilandelayo:
- Indawo okuhlalwa kuyo iyakhululwa ngezinqubo okungenzeka ukuthi azisasebenzi, okwenza kube nesikhala sezinqubo ezintsha ezizosingathwa.
- Yandisa isivinini nokusebenza uma uphequlula i-inthanethi, ikakhulukazi uma sichitha isikhathi esiningi ku-inthanethi futhi sivula amakhasi ewebhu ahlukahlukene.
- Imikhondo yedatha yomuntu siqu iyasuswa ezigcinwe okwesikhashana kunqolobane, okunciphisa ubungozi bokuveza ulwazi olubalulekile noma oluyimfihlo, ikakhulukazi uma sisebenzisa amakhompyutha omphakathi noma okwabelwana ngawo.
- Iziphazamisi zesiphequluli zilungisiwe, njengamakhasi angalayishi. Ngaphezu kwalokho, inguqulo yakamuva yekhasi lewebhu iyaboniswa.
Okokugcina, khumbula ukuthi ukusula inqolobane akufani nokusula idatha kumadivayisi akho. Njengoba sesichazile, amakhophi edatha agcinwa kunqolobane ukuze kusheshiswe ukwenziwa kwezinqubo. Ngakho ukusula inqolobane akususi izilungiselelo noma okuncamelayo, futhi akususi idatha egcinwe kusigcinalwazi sakho.
