Nawa KB a cikin MB ko GB? Nemi yadda kwamfutarka na da kowane.
Idan kun ji damu game da yawan ƙwaƙwalwar ajiya da ajiya kwamfutarku na da, kuma kullun da KBs, MBs, da GBs ya ba ku, ba abin mamaki bane. Akwai raguwa da yawa a cikin lissafi, da kuma wasu lokuta mawuyacin lambobi bayan hade da su.
Akwai hanyoyi guda biyu na bayyana filin ajiya da ƙwaƙwalwar ajiyar kwamfutarka. Wannan bayani ne mai sauƙi game da abin da ke faruwa, amma idan ba ku so math a bayan amsa ba, za ku iya tsallake zuwa ƙarshen.
Fahimtar Binary vs. Lambar Ƙididdiga
Na farko, taƙaitaccen darasin math. Muna yin math ɗin mu na yau da kullum a cikin tsarin adadi. Tsarin decimal yana da lambobi goma (0-9) wanda muke amfani da su don bayyana duk lambobinmu. Kwamfuta, saboda dukkanin abubuwan da suke da mahimmanci, suna dogara ne kawai akan waɗannan lambobi biyu, 0 da 1 wanda ke wakiltar alamun "a" ko "kashe" na kayan aikin lantarki.
Wannan ake kira tsarin binary, kuma nau'ikan nau'ikan nau'i ne kuma waɗanda aka yi amfani da su don bayyana yawan lambobi. Alal misali, don samun lambar adadi na 4 a cikin binary za ku ƙidaya kamar wannan: 00,01,10,11. Idan kana so ka tafi mafi girma daga wannan, kana buƙatar karin lambobi.
Mene ne Bits da Bytes?
A bit shi ne ƙaramin increment na ajiya a kwamfuta. Ka yi la'akari da kowane abu kamar walƙiya mai haske. Kowane ɗayan yana a kunne ko a kashe, don haka yana iya samun ɗaya daga cikin dabi'u biyu (ko dai 0 ko 1).
A byte ne mai layi na takwas ratsi (ramukan haske takwas a jere). A byte shine mahimmin ƙananan bayanan da za a iya sarrafawa akan kwamfutarka na iyali. Saboda haka, ana amfani da sararin ajiya a ma'aunin ajiya maimakon ƙwallon ƙafa. Mafi yawan ƙimar adadi wanda mai byte zai wakilta shine 2 8 (2 x 2 x 2 x 2 x 2 x 2 x2 x2) ko 256.
Don ƙarin bayani game da lambobi binary, ciki har da yadda za a sake mayar da su zuwa decimal, don Allah a duba yankin da ke ƙasa.
A kilobyte (KB) a cikin binary shine 1024 bytes (2 10 ). Kalmar "kilo" tana nufin dubban; Duk da haka, a cikin binary kilobyte (1024) dan kadan ya fi girma ƙayyadaddun (1000). Wannan shi ne inda abubuwa ke fara rikici!
Magabyte a binary shine 1,048,576 (2 20 ) bytes. A ƙananan adadi yana da 1,000,000 bytes (10 6 ).
Wani babban abu mai mahimmanci shine ko dai guda biyu (1,073,741,824) bytes ko 10 9 (1 biliyan) bytes. A wannan batu, bambancin tsakanin binary version da decimal version ya zama mahimmanci.
To, Yaya Mafi yawan Kwaffi / ajiya Ina da Ni?
Dalilin da ya sa mutane suke rikita rikice shi ne cewa wani lokaci masana'antun suna ba da bayani game da lalatawa kuma wani lokacin sukan samar da shi a binary.
Ana fitar da matsaloli masu wuya, masu motsi na flash, da sauran na'urori masu ajiya a cikin ƙaddarar sauƙi don sauki (musamman a lokacin da tallace-tallace zuwa mabukaci). Ƙwaƙwalwar ajiya (kamar RAM) da software suna samar da dabi'u binary.
Tun da 1GB a cikin binary ya fi girma fiye da 1GB, sauranmu muna rikita rikice game da yadda za mu iya amfani / amfani. Kuma mafi mahimmanci, kwamfutarka na iya cewa yana da rumbun kwamfutarka 80GB, amma tsarin da kake yi (wanda ya yi rahoton a binary!) Zai gaya muku cewa yana da ƙananan (ta game da 7-8 GB).
Mafi kyawun bayani ga wannan batu shine kawai ka watsar da shi yadda ya kamata. Lokacin da ka sayi na'urar ajiya, tuna cewa kana samun dan kadan kadan fiye da yadda kuke tunani da tsara yadda ya dace. M, idan kana da 100 GB a cikin fayiloli don adana ko software don shigarwa, za ku buƙaci kundin kwamfutarka tare da akalla 110 GB na sarari.
