Mayunitsi a mudziwe

Unit amapezeka pa munda wa zochita za anthu monga ochiritsira ofanana muyeso chilichonse. Volume, kutalika ndi kulemera - ambiri mwa anthu alipo. M'mayiko osiyanasiyana, zinenero zosiyanasiyana, mosaganizira chipembedzo, ife ntchito choyezera yemweyo amatanthauza. Pakuti munthu zili lomwenso ndi zomveka, izo sikutanthauza kanthu kuti angatembenuke, zomwe nthawi zambiri kumayambitsa zolakwika.

Mkubwela kwa kompyuta moyo wa munthu, palinso kukhazikitsa gulu limodzi la mudziwe kuchuluka. Inde, ngati kuti amaona ndipo Chinese, ndi American, ndi kompyuta lina lililonse padziko lapansi. Onse mapulogalamu a dziko angakhoze ntchito monga chinenero chimodzi. Choncho pang'ono ndi logarithm bayinare.

Pang'ono - unit wa mudziwe wofanana mudziwe chiwerengero ndi odzimva makhalidwe awiri okha "pa" ndi "kusiya" (kumujambula 1 ndi 0). Kuti kompyuta encode zilembo English, zidutswa zisanu ndi chokwanira, koma kukwaniritsidwa kwa zovuta kwambiri ndondomeko mapulogalamu Pakufunika zambiri buku mayunitsi mudziwe zimene anaitenga ku Latin masamu manambala oyambirira. Tinthu mu kompyuta - Ndi zimachitika magetsi umaperekedwa ku positi lamulo thupi wamkulu ndi kugula reciprocal la ntchito. 0 1 malamulo ali ranges osiyana voteji. Zonsezi zikuchitika pa anthu thamanga kwambiri, mofanana ndi kulanda zambiri pakati ubongo ndiponso mitsempha mathero mu thupi la munthu.

zinenero zonse mapulogalamu angamvetsere kuti malamulo bayinare. Photos anasamutsa mu mawonekedwe a pakompyuta, masewera ndi pulogalamu iliyonse mapulogalamu, kasamalidwe kupanga makina - zonse ntchito wamba mayunitsi mudziwe - pang'ono.

Kusonkhanitsa mu Akamva nyemba unyolo kupanga zinthu zatsopano kuyeza wagawo: mabayiti, kilobits, kilobytes, megabits, megabytes, gigabytes, terabytes, PB ndi zina zotero.

Mamvekedwe amaganiza kuti Akamva eyiti ndipo ali ndi dzina chachiwiri - octet monga mwa mbiri kompyuta pali njira monga 6-bit mabayiti 32-bit, koma mapulogalamu Njira yothetsera ena makampani kusintha kwa unit zomwe sanatipatse zotsatira zipatso. Koma chachikulu ndi eyiti-bit mamvekedwe, wotchedwa dzina wamba "octet".

Magawowa anathetsera zambiri, chiwerengero cha mayunitsi a mudziwe ndiyotengera mu mwapadera ovomerezeka tebulo mtundu Unicod, ndi mitundu ina wolemba pulogalamu ntchito Windows Os kapena chimzake. Aliyense wa matebulo ntchito cholinga chake. Chifukwa wakuda ndi woyera chithunzi ntchito 8-bit dongosolo bayinare, ndi kwa mtundu uli kale 24-bit. Kulemba nkhani mu chinenero cha dziko kugwiritsa ntchito 16-bit UNICOD zokwanira.

Pa nthawi, wosuta pafupifupi alipo tasam chachikulu unit wa mudziwe ngati terabyte ndi - ndicho 1.024 gigabytes, zomwe zimapanga Nayenso 1.024 gigabytes. Ngati inu kuchulukitsa ndi 1024, timapeza chiwerengero cha megabytes amene amapanga terabyte wina. Ngati yosavuta chulutsa mpaka unit koyamba, ndiyeno nkutembenuka pa tsiku loyamba la, mu Chiwerengero aliyense si woyenera. Ichi chidzakhala chiwerengero cha zizindikiro bayinare kuti akufunika kudzaza m'buku lino.

Ndipotu opanga ambiri zigawo zikuluzikulu ntchito issuance tanthauzo lenileni la prefixes kilo, Mega ndi giga. Zimenezi zimabweretsa zolakwika zikuluzikulu ndipo uphimbika chinyengo. Ndiko kuti, litayamba molimba 1 terabyte thupi angathe kusunga okwana 950 megabytes deta. ammudzi kompyuta yakhala anapereka njira kupewa izo.

Prefixes kilo, Mega, ndi zina zotero kukhala ndi zinthu zawo mwachizolowezi. Kilo - chikwi, Mega - miliyoni. Pakuti zida kompyuta kugwiritsa ntchito bwino ndi multiplier si 1000 ndipo 1024. Dzina iyenso anatulukira - KIBI. Ndi, prefixes lolondola ndi kuchulukitsa ndi: kibi-, mibi- ndi kupitirira.
