Zingaphi KBs kwi-MB okanye i-GB? Fumana ukuba ikhompyutha yakho ininzi kangakanani.
Ukuba uziva udidekile malunga nokuba imemori kunye nokugcinwa kwendawo ekhompyutheni yakho inakho, kwaye ukhonjiswe yiK KBs, MBs, ne-GBs, akumangalisi. Kukho ezininzi izifinyezo kwi-computing, kwaye ngamanye amaxesha amanxeba adibanisayo emva kokudibana nabo.
Kukho iindlela ezimbini ezahlukeneyo zokubonisa indawo yokugcina kunye nememori yekhompyutha yakho. Le ngcaciso elula yento eyenzekayo, kodwa ukuba awufuni izibalo emva kwempendulo, unokweqa ngokuthe ngqo ukuya ekupheleni.
Ukuqonda iBhinary vs. Numimal Numbers
Okokuqala, isifundo esifutshane sematriki. Senza izibalo zethu zemihla ngemihla kwinkqubo yokugqibela. Inkqubo yokugqibela idijithi ezilishumi (0-9) esisebenzisayo ukubonisa zonke iinombolo zethu. Iikhomputha, ngenxa yazo zonke eziyinkimbinkimbi ezibonakalayo, ekugqibeleni zisekelwe kwizinto ezimbini nje kwezo zidijithi, i-0 kunye ne-1 emela "kwi" okanye "ngaphandle" izixhobo zamandla kagesi.
Oku kuthethwa njengenkqubo yebhanari, kunye nezixhobo zeros kunye nazo zisetyenziselwa ukubonisa ixabiso lamanani. Umzekelo, ukufikelela kwinombolo ye-decimal kwi-binary uya kubala oku: 00,01,10,11. Ukuba ufuna ukuya phezulu kunelo, udinga amanani amaninzi.
Ziziphi iiBits kunye nee-Byte?
Kancinci ukwanda okuncinci kokugcinwa kwikhompyutha. Khawucinge ngento nganye ifana ne-bulb. Ngamnye uvumelekile okanye uyacima, ngoko ke unokuba nexabiso elilodwa (okanye i-0 okanye 1).
I- byte ngumtya wesibhozo ezisibhozo (iibhola zokukhanya ezisibhozo zilandelana). I-byte iyona yunithi yincinci yedata engacatshungulwa kwikhompyutheni yakho yintsapho. Ngaloo ndlela, indawo yokugcina igcinwa ngama-bytes kunokuba ibitshi. Ixabiso elidlulileyo eliphezulu elingamelwa yi-byte li-2 8 (2 x 2 x 2 x 2 x 2 x 2 x2 x2) okanye 256.
Ukufumana ulwazi oluthe xaxa kumanani amabini, kuquka ukuguqulwa kwinqanaba, nceda ubone indawo yendalo enezantsi.
I- kilobyte (KB) kwi-binary ngu-1024 bytes (2 10 ). Isiqalo se "kilo" sithetha iwaka; Nangona kunjalo, kwi-kilobyte yebinki (1024) yinto encinci kuneyona nkcazelo yokugqibela (1,000). Yilapho izinto ziqala ukudideka!
I- megabyte kwi-binary yi-1,048,576 (2 20 ) bytes. Kwinqanaba li-1,000,000 byte (10 6 ).
I- gigabyte i-2 30 (i-1,073,741,824) i-bytes okanye i-10 9 (1 billion) bytes. Kulo nqaku, umahluko phakathi kwenguqulo yebhinari kunye neyesiqulatho sesigqiba iya kuba yinto ebalulekileyo.
Ngoko Ingaba Imemori / Isitoreji Ngaba Ndinayo?
Isizathu esikhulu sokuba abantu badideke kukuba ngamanye amaxesha abavelisi banikezela ngolwazi kwixesha elide kwaye ngamanye amaxesha banikezela ngokubhaliweyo.
Ukuqhutshwa kanzima, ukuqhuma kwefowuni, kunye nezinye izixhobo zokugcina zivame ukuchazwa kwisidanga sokuba kube lula (ngakumbi xa kuthengiswa kumthengi). Imemori (efana ne-RAM) kunye neprojekhthi zibonelela ngokubaluleka kwamanani.
Ukususela kwi-1GB kumbhinqa mkhulu kune-1GB kwisidanga, abanye bethu badla ngokudideka malunga nokuba sininzi kangakanani indawo esiyifumanayo / ukuyisebenzisa. Okubi nakakhulu, ikhomputha yakho inokuthi ithi ine-80GB drive drive, kodwa inkqubo yakho yokusebenza (echaza ingxelo kwi-binary!) Iya kukuxelela ukuba ingaphantsi (malunga ne-7-8 GB).
Isisombululo esilula kakhulu kulo mbandela kukungayihoyi nje ngangokunokwenzeka. Xa uthenga i-device yokugcina, khumbula ukuba ufumana ngaphantsi ngaphantsi kokucinga kwakho kwaye uceba ngokufanelekileyo. Ngokwenene, ukuba unayo i-100 GB kwiifayile ukugcina okanye isofthiwe yokufakela, uya kufuna idiski ekhuni kunye ne-110 GB yendawo.
