Kunzwisisa Kuparidzirwa vs. Zvechokwadi Drive Storage Capacities
Pane imwe nguva, vazhinji vashandisi vasangana nemamiriro ezvinhu apo kukwanisa kwekutya kana dhayi hakusi yakakura sekutsvaga. Kazhinji, izvi hazvina maturo kumutsa mutengi. Ichi chinyorwa chinotsanangura kuti vakugadziri vanokwanisa sei kukwanisa kuchengetedza zvigadzirwa zvakadai sekufambisa zvinotyisa , kutenderera kwakasimba , maDVD uye Blu-ray discs zvichienzaniswa nehukuru hwavo chaihwo.

Zvose zvinowanikwa pamakombiyuta zvakachengetwa mumutambo webhanari seimwe kana zero. Eight yezvibatanidza pamwe chete inoita inonyanya kutaurwa-pane chinhu mukombiyuta, inte. Izvo zviyero zvakasiyana zvekuchengetedza simba zvinorondedzerwa nechikamu chekutanga chinomiririra chiyero chakasiyana, chakafanana nematricx prefixes. Sezvo makombiyuta ose akavakirwa pamatanha emabhadha, aya mafiropu anomiririra chikamu chechipiri. Zuva rimwe nerimwe nhamba yekuwedzera kwemasimba maviri kusvika ku100. Zvose zvinowanikwa kare zvinotevera:
- Kilobyte (KB) = 1,024 bytes
- Megabyte (MB) = 1,024 kilobytes kana 1,048,576 bytes
- Gigabyte (GB) = 1,024 megabytes kana 1,073 741 824 bytes
- Terabyte (TB) = 1,024 gigabytes kana 1 099 511 627 776 bytes
Izvi zvakakosha ruzivo nokuti kana kombiyuta inoshandisa chirongwa kana purogiramu inoshuma nzvimbo inenge iripo kune motokari, ichazopa huwandu hwehuwandu hwaihwo huripo kana hutsanangudzo yavo neimwe ye prefixes. Saka, iyo OS inoratidzira nzvimbo yose ye 70.4 GB chaizvoizvo inenge inenge 75,591.424 409 bytes yekuchengetedza nzvimbo.

Sezvo vashandi vasingafungi muchitsiko chemasvomhu 2, vashandi vakasarudza kuenzanisa zvikuru motokari zvigadziro zvichienderana nehuwandu hwemashamba gumi nhamba isu tese tinojaira. Nokudaro, rimwe gigabyte rakaenzana nemabhiriyoni rimwe bytes, asi imwe tababyte inokwana imwe trillion bytes. Izvi zvaisava dambudziko guru zvakare kana tikashandisa kilobyte, asi imwe nhanho yekuwedzera mumugumo wekutanga inowedzerawo kukanganisa kwakazara kwemaoko chaiwo zvichienzaniswa nezvimbo yakaparidzirwa.
Heino nhaurirano inokurumidza kuratidzira mari iyo maonero chaiwo anosiyana kana ichienzaniswa nechinoshandiswa kune imwe neimwe inowanikwa inofanirwa kukosha:
- Megabyte kusiyana = 48,576 bytes
- Gigabyte kusiyana = 73741 824 bytes
- Terabyte kusiyana = 99 511 627 777 bytes
Kubva pane izvi, kune gigabyte imwe neimwe inogadzirwa nemotokari, inopfuura-kureva kuti yakawanda disk space ne 73 731 824 byte kana inenge 70.3 MB ye disk space. Saka, kana mugadziri anotengesa 80 GB (80 bhiliyoni bytes) hard drive, chaiyo disk space inenge 74,5 GB ye nzvimbo, inenge 7 muzana pasi pezvakadhindwa.
Izvi hazvisi chokwadi kune zvose zvinotungamirira uye kuchengetedza mhizha pamusika. Apa ndipo apo vatengi vanofanira kuchenjerera. Mafambiro akaoma akawanda anorondedzerwa zvichienderana nehuwandu hwezvinhu zvinozivikanwa apo gigabyte imwe bhiliyoni rimwe. Kune rumwe rutivi, vazhinji vanofambisa mashoko vekuchengetedzwa kwepamusoro kunobva pane chaiyo yekuyeuchidza zviyero. Saka 512 MB memori kadi ine 512 MB chaiyo yehuwandu hwemashoko. Imhizha iyi yave iri kuchinja pane izvi zvakare. Semuenzaniso, SSD inogona kuverengwa se 256 GB model asi ine 240 GB nzvimbo. Vashandi veSSSD vanoisa pane imwe nzvimbo yemafa akafa uye nebhadhayasi vs. kusiyana kwechirevo.
Akafananidzirwa vs. Unformatted
Kuti chero rudzi rwekuchengetedza ruzivo rwuve runoshanda, panofanira kunge kune imwe nzira yekombiyuta kuziva kuti mabheji akachengetwa mairi anorevei kune mamwe mafaira. Iyi ndiyo iyo kuumbwa kwemotokari kunopinda . Mhando dzemafomu ekufambisa dzinogona kusiyana zvichienderana nekombiyuta asi dzimwe dzowanowanikwa ndeye FAT16, FAT32 uye NTFS. Muchimwe nechimwe chezvinhu izvi zvinogadzirisa zvirongwa, chikamu chekuchengetedza nzvimbo inopiwa kuitira kuti data iri pairi inogona kunyorwa kuitira kuti kombiyuta kana imwe chimbo chiverengere kuverenga zvakanaka nekunyora data kune motokari.
Izvi zvinoreva kuti kana motokari yakagadziridzwa, basa rekuchengetedza nzvimbo yefambisi iri pasi pehuwandu hwaro husingazivikanwi. Nhamba iyo nzvimbo yakaderedzwa inopesana zvichienderana nehuwandu hwekugadzirisa hunoshandiswa pakudha uye pamwe uye chiyero uye ukuru hweiyo mafaira akasiyana-siyana pahurongwa. Sezvo zvichinyatsosiyana, hazvigoneki kuti vakugadziri vatidze ukuru hwakarongeka. Dambudziko iri rinowanzotarisana ne- flash media storage kunze kwekukura kukuru kwekutyaira.
