Bangaki amakhilobhayithi Megabyte? Sekuyisikhathi ukwazi wonke umuntu!

Akukhona nje esikoleni yebo computer science kudinga ulwazi mayelana amakhilobhayithi eziningi kanjani ngendlela megabyte. izimo yamanje ukubeka abavamile abasebenzisa i-Internet ukuba kumile lo mbuzo olula. Ukwazi impendulo, ungasho, isibonelo, kangakanani umculo ungakwazi agqoke abezindaba ezinye esikhiphekayo. Ngakho-ke, ake sibone ukuthi singakanani e MB amabhayithi.

Ekuqaleni, iyunithi zonke izibalo computer washaywa. Ngemva amavolumu Imininingwane eqala ukukhuluphala, waqala ukwandisa isibalo wachitha inkumbulo amaseli. Manje-ke kwenzeka ukuthi 1 ibhayithi = 8 izingcezu. Ngesizathu esithile kufanele kube lula ukuwakhumbula. Ngaphezu kwalokho, kubantu abawaziyo izibalo noma i-physics, kuyoba kancane sobala. Igama elithi "kilobyte" ezakhiwe ibhokisi set-top, nakho kusho 10 ^ 3. Lokhu kusho ukuthi 1 kB = 1024 bytes. Lapho benza zokugcina Izinombolo ezimbili, akudingekile kokubuka ikakhulukazi kusukela bengebona ezibaluleke kakhulu. Ngakho, siye ususondela umbuzo ka amakhilobhayithi eziningi kanjani ngendlela megabyte.

Ebhekisela futhi ulwazi jikelele, okuyinto ihlanganisa yizinqamu eziningana isayensi "wemvelo". Yena waziwa elinye Isiqalo "Mega", okusho ukuthi 10 ^ 6 (noma kwesigidi ezahlukene). Okungukuthi, maqondana amabhayithi 1 MB = 1,000,000 b. Lokhu kuvamile kakhulu okwamanje ukubaluleka lapho ephawula Usayizi sebuningini amafayela. Nokho, kufanele kusho ukuthi esikhathini esizayo esiseduze kungenzeka gxuma isihlobo kwezinye inkumbulo lokungcolisa, okuholela a shift kwezinye aduduze njengoba main. Indlela logic nolwazi ezincane zemvelo sesamukele, bangaki amabhayithi endaweni megabyte. Kwakumelwe ayisigidi.

Sekuyisikhathi ujike yombuzo main, impendulo lapho sesizokwenza. iminithi Okokuqala wezibalo:

1 kb = 1024 b;

1000000 1 mb = b;

1 mb = 1,000 kb.

Manje ngosizo indlela zezibalo iye waphendula umbuzo mayelana amakhilobhayithi eziningi kanjani ngendlela megabyte. Njengoba ubona, kukhona into ekhethekile. izibalo Ordinary kuzokusiza esimweni esinzima. Hhayi ukuba okungenasisekelo, ake sicabangele isibonelo njalo umsebenzi wesikole.

Ake sithi drive yakho isikhala mahhala 200 MB. Futhi udinga ukubeka kuso usayizi wefayela mbhalo 700 KB. Inombolo yabo kumele bavame infinity (lena isimo), kodwa elinganiselwe ngosayizi. Umbuzo ilula: kangakanani uzoba ukulondoloza idokhumenti?

Isixazululo kanje. Ukuze uqale, oyikhumbulayo kangakanani megabyte kilobyte. Kulesi sigaba, inhloko has ukuza mbono unembile ukuthi 1 MB = 1024 KB. Khona-ke uyaqaphela ukuthi onawo 200 * 1024 = 204,800 KB. Le nombolo lihlukaniswe by ubukhulu amafayela. Okungukuthi, n = [204800/700] = 292. I abakaki square isho inamba ingxenye inombolo, ngoba ifayela kungenziwa kuphela ifakwe ngokugcwele, ngaphandle kokushintsha lingakanani. Inombolo abasabeli n. Lesi sibonelo elula sibonisa kuphela indlela, ngokomthetho bangasebentisa lolwati mayelana amakhilobhayithi eziningi kanjani ngendlela megabyte.

Ngakho ngayithola impendulo, wabuza umbuzo othi ngaphambili. Sikhombisa yokuthi computer kuyinto akunandaba ngempela. Konke ehlangene nabo, kungenzeka ukubala, usebenzisa hhayi olunzulu kakhulu.
