Ndi mphamvu zilembo chiyani? Kodi kupeza mphamvu ya zilembo: chilinganizo

Modern kompyuta luso, informatics, zilembo mphamvu, dongosolo analipo ndi mfundo zina zambiri ndi kugwirizana kwambiri pakati pa iwo. ochepa kwambiri anthu lero bwino nkhani imeneyi. Tiyeni tiyese kufotokozera mphamvu ya zilembo, mmene kuwerengera ndi ntchito mchitidwe. Mtsogolo, ichi palibe chikaiko, zingakhale zothandiza kuchita.

Kodi mudziwe

Asananyamuke kufufuza funso kodi cardinality wa alifabeti, ndipo ambiri, chimene icho chiri, inu muyenera kuyamba, titero, kuchokera zikande.

Ndithudi ife tonse tikudziwa kuti lero pali wapadera chingwe dongosolo laphindu, pa maziko a makhalidwe kutchulidwa. Mwachitsanzo, chifukwa makhalidwe ofanana kwa malo ndi mamita, chifukwa misa ndi kulemera - kulemera kwa intervals nthawi - masekondi, etc.

Koma mmene kuyeza buku la mudziwe m'lingaliro lemba? Ichi ndi chifukwa chake chiphunzitso cha mphamvu ya zilembo polima.

Kodi mphamvu zilembo: mfundo koyamba

Choncho, ngati inu kutsatira Tinganene kuti phindu chomaliza cha kuchuluka ali chizindikiro kumene kumatsimikizira chiwerengero cha nthawi unit patchulidwa zakhala zikuzunza m'miyoyo mu mtengo mpandawo, tinganene kuti mphamvu ya zilembo ndi chiwerengero cha anthu otchulidwa ntchito chinenero makamaka.

Kuti izo bwino, tiyeni kusiya funso mmene kupeza mphamvu ya zilembo pambali, ndipo kulabadira zilembo okha, ndithudi, mwa mawu a sayansi zambiri. Ziri kulankhula, ndi mndandanda wa zizindikiro ntchito lili makalata, manambala, m'mabokosi osiyanasiyana otchulidwa mwapadera, zopumira, etc. Komabe, ngati ife tikuyandikira kufunsa kuti mphamvu ya zilembo ndi njira kompyuta ofotokoza ayenera talemba muno komanso kusiyana (kusiyana pakati pa mawu umodzi kapena zizindikiro zina).

Mwachitsanzo Chirasha, kapena kani, kiyibodi Kamangidwe. Zochokera kumwamba, ndi mndandanda uli 33 makalata, manambala 10 ndi 11 otchulidwa mwapadera. Choncho, munkalowa a zilembo ndi 54.

chizindikiro Information kulemera

Komabe, mfundo zonse za mphamvu ya zilembo silitchula chikhalidwe cha mawerengedwe a mabuku a m'lemba mudziwe munali makalata, manambala ndi zizindikiro. Izi zimafunika njira yapadera.

Kwenikweni, ine ndikuganiza, chabwino, izo ziri angakonde osachepera anaika mu mawu a dongosolo computer, mmene anthu ambiri akhoza kugwira? Yankho: awiri. Apa pali chifukwa. mfundo ndi yakuti aliyense chikhalidwe, kaya kalata kapena manambala ali ake kulemera mfundo imene makina ndi kuzindikira kuti kutsogolo kwake. Koma kompyuta amadziwa chizindikiro mu mawonekedwe a anthu ndi maziro zimene Ndipotu, anayambitsa sayansi lonse.

Choncho khalidwe aliyense akhoza umaimiridwa ndi mbali chikukhudza manambala 1 ndi 0, i.e., ndondomeko kochepa kusonyeza kalata, nambala kapena chizindikiro tichipeza zigawo ziwiri.

Chimodzimodzi mudziwe kulemera, kutengedwa ngati unit muyezo mfundo amatchedwa pang'ono (1 pang'ono). Motero, 8 Akamva amapanga mamvekedwe wina.

Chifaniziro cha zilembo code bayinare

Choncho, kodi mphamvu ya zilembo, ine ndikuganiza, ndi pang'ono zomveka. Tsopano yang'anani pa mbali, makamaka zothandiza kuzindikira mphamvu ntchito malamulo bayinare. Monga chitsanzo kwa kuphweka ife kutenga zilembo munali chizindikiro 4 okha.

Awiri manambala bayinare malamulo zinayendera ndi chizindikiro mudziwe tinganene motere:

Choncho - losavuta mapeto: mphamvu N = 4 zilembo chizindikiro wagawo kulemera ndi 2 Akamva.

Ngati tigwiritsa ntchito zitatu manambala bayinare malamulo zilembo Mwachitsanzo, ndi makhalidwe 8, chiwerengero cha ma adzakhala:

M'mawu ena, pamene mphamvu ya zilembo N = 8, kulemera kwa chizindikiro chimodzi kwa atatu manambala bayinare malamulo ndi wofanana 3 Akamva.

Kodi kupeza mphamvu ya zilembo ndi ntchito mawu kompyuta

Tsopano tiyeni tiyese kuyang'ana ubale akufotokoza chiwerengero cha manambala code ndi mphamvu ya zilembo. Chilinganizo kumene N - zilembo afabeti mphamvu, ndi B - chiwerengero cha manambala Mpambo bayinare lidzaonekera izi:

N = 2 ^b

Ie, 2 ¹ = 2, 2 ² = 4, 2 ³ = 8, 2 ⁴ = 16, etc. Ziri chilankhulire, chiwerengero manambala a malamulo bayinare chizindikiro kulemera. Kumbali ya mudziwe izo zikuwoneka ngati izi:

Muyeso buku deta

Komabe, iyo inali chabe Mwachitsanzo losavuta kotero kunena pakuti kumvetsa koyamba zomwe mphamvu ya zilembo. Chitani mwachindunji kuchita.

Pa nthawi imeneyi chitukuko makompyuta kwa capitalization kalembedwe maziko zazikulu ndi lowercase makalata, Chisililiki ndi makalata Latin, zopumira zizindikiro, parentheses, zizindikiro masamu, etc. Ndi ntchito zilembo 256. Zochokera chakuti ndi 2 256 ^8, munthu mosavuta ndikuganiza kuti kulemera kwa wina chizindikiro cha alifabeti iyi 8, i.e., Akamva 8 kapena 1 mamvekedwe.

Ngati tingayerekezere magawo onse amene akudziwika, inu mosavuta kupeza chofunika kufunika kwa mfundo buku la mawu alionse. Mwachitsanzo, tili ndi mawu kompyuta, munali 30 masamba. tsamba limodzi ndi mizere 50 zilembo 60 kapena chikhalidwe chilichonse, kuphatikizapo malo.

Choncho, tsamba limodzi adzakhala ali 50 × 60 = 3000 mabayiti mauthenga, ndi malemba onse - 3,000 × 50 = 150,000 mabayiti. Monga mukuonera ngakhale mawu yaing'ono amayezedwa mabayiti wovuta. Nanga laibulale lonse?

Pankhaniyi bwino kumasulira mu mtengo amphamvu kwambiri buku - kilobytes, megabytes, gigabytes, etc. Zochokera chakuti Mwachitsanzo, 1 kilobyte ndi 1024 mabayiti (2 ^10), ndipo megabyte - February ¹⁰ kilobytes (1,024 Kbytes), n'zosavuta kuwerengera kuti kuchuluka kwa mfundo mawu ndi mawu masamu Mwachitsanzo uyu adzakhala 150000/1024 = 146 484 375 kilobytes kapena megabytes pafupifupi 0,14305.

m'malo posleloviya

Ambiri, ndi mwachidule ndi onse, ndi nkhani kuganizira zimene mphamvu ya zilembo. Mpaka kuwonjezera kuti kulongosola anali ntchito njira mwangwiro masamu. Ndizosachita kunena kuti katundu zamalankhulidwe lemba la mu nkhani iyi si.

Koma, ngati ife tikuyandikira review za izo pamalo wopereka munthu chinachake kuganizira, akonzedwa a ma tanthauzo kapena mbali za anthu otchulidwa mu nkhani imeneyi adzakhala ndi ziro magalimoto katundu, ngakhale ku maganizo ndi maganizo buku deta, zotsatira akadali zosatheka kuwerengetsa.

Ambiri, chidziwitso cha mphamvu ya zilembo ndi mfundo ofanana si zovuta kumvetsa pulayimale ndipo angagwiritsidwe ntchito m'njira ya kanthu. Pankhaniyi, wosuta aliyense pafupifupi tsiku lililonse anakumana ndi ichi. Amapereka chitsanzo cha Mawu purosesa otchuka kapena mlingo yemweyo, amene amagwiritsa m'njira imeneyi. Koma sizikusokonezani ndi alipidwa "polembapo." Apa zilembo mphamvu m'munsi, kuyambira kalembedwe si ntchito Mwachitsanzo, likulu makalata.
