Kutheni i encoding kabini iphela? iindlela zokuhlela

Le khompyutha Iinkqubo isixa esikhulu solwazi. Iifayile zesandi, imifanekiso, umbhalo - nonke ufuna ukudlala okanye ukubonisa. Kutheni binary esephepheni yindlela jikelele iinkqubo data zaso nasiphi na isixhobo technical?

Yintoni yahlukile ngokufihlisa ikhowudi?

Ngokuqhelekileyo abantu equate ingqiqo ka "ukhowudo" yaye "elizinyelisiweyo", xa enyanisweni banayo iintsingiselo ezahlukeneyo. Ngenxa yoko, ukubethela inkqubo yokuguqulwa ulwazi ukuze ukusifihla. Ukuwufunda abakwazi umntu abatshintsha okubhaliweyo, okanye abantu abaqeqeshwe ngokukodwa. Esephepheni isetyenziselwa processing of ulwazi lula lokusetyenziswa kuye. itheyibhile ikhowudi efanayo nesetyenziswa rhoqo, kwiimeko eziqhelekileyo, ukuya wonke. It is eyakhelwe kwi computer yakho.

binary isimiso esephepheni

encoding Binary isekelwe phezu ngokusetyenziswa weesimboli ezimbini kuphela - 0 no 1 - nokuhlawulwa ulwazi esetyenziswa izixhobo ezahlukeneyo. Le miqondiso ngokuba amanani yokubini, IsiNgesi - digit yokubini, okanye bit. Ngalinye iisimboli lwekhowudi yokubini esigcwalisa inkumbulo ngekhompyutha ukuze 1 bit. Kutheni binary esephepheni yindlela jikelele zokulungisa kakuhle ulwazi? Isibakala sokuba lula ikhompyutha ukusingatha ezimbalwa. Ukususela oku kuxhomekeke kunye nokusebenza le PC: imisebenzi ezisebenzayo kangako kuyimfuneko ukwenza ifowuni, loo oluphezulu isantya kunye nomgangatho lomsebenzi.

binary Umgaqo esephepheni ifumaneka kuphela kweenkqubo. Ngenxa alternation of qegu kunye igubu yaveza uyambetha Polynesians nokudlulisela ulwazi omnye komnye. Umgaqo ofanayo uyasebenza e worse ikhowudi, apho izandi elide elifutshane kwaye zisetyenziswa ukudlulisa umyalezo. "Alphabet ngeengcingo" namhlanje.

ukusebenzisa Apho encoding yokubini?

I binary esephepheni kwengcaciso kwikhompyutha isetyenzisiwe kuyo yonke indawo. ifayile nganye, nokuba oko umculo okanye itekisi ekufuneka zahlelwa ukuze kube kamva lula iphathwe nokufunda. binary inkqubo Coding Iluncedo kusebenzo kunye neesimboli kunye neenombolo, iifayile odiyo, imizobo.

encoding Binary kwamanani

Ngoku amanani computer zimelwe kwifomu ikhowudi, Akukwazi kumntu avareji. Ukusetyenziswa Amanani Arabhu, njengoko ngqondweni, kuba indlela usebenze. Isizathu soku yimfuneko ukuba zinyule inombolo ekhethekileyo umlinganiswa ngamnye ntoni ngamaxesha akunakwenzeka.

Kukho olubhalo ezimbini: ngokokuma kunye nepozitsionnyh. inkqubo Nepozitsionnyh isekelwe phezu ukusetyenziswa koonobumba Latin kwaye bayazazi kuthi ngohlobo yamanani zamaGrike. Le ndlela ukurekhodwa kakhulu nzima ukuqonda, ke ngoko, yayekwa.

Inkqubo inani ngokokuma esetyenziswayo namhlanje. Ezi ziquka binary, idesimali, elinekona ezintandathu kunye hexadecimal nokhowudo nokuba ulwazi.

Decimal inkqubo Coding sisebenzisa kubomi bemihla ngemihla. Kuyinto eqhelekileyo ukuba thina Amanani Arabic, ezo luqondakale wonke. Binary encoding amanani ezahlukeneyo usebenzisa zero enye kuphela.

Integers eziguqulelwe kwi iikhowudi lokubini ngokwahlula kubo 2. kuphumela buso kwakhona yahlulwe izigaba ezibini, de ekugqibeleni 0 okanye 1. Umzekelo, inani 123 ₁₀ notation lokubini angamelwa kwifomu ₂ 1111011. A Inani: 20 ₁₀ 10100 _{izakujongeka-2.}

Ekwandiseni 10 no-2 zibonakaliswe amanani ngokulandelelana zokubini nempahla iidecimal nokhowudo nkqubo. uphawu esephepheni binary isetyenziselwa ukuze kube lula ukusebenza amaxabiso thaca kwiinkqubo inani ezahlukeneyo.

Programming ubuchule amanani wokugqibela zisekelwe kwi "lencopho equkuqelayo". Ukuze akhuphele ngokufanelekileyo ixabiso ukusuka kwishumi ukuya kwinkqubo yokubini ikhowudi usebenzisa ifomula N = M x qp. M - ke mantissa (ngaphandle ibinzana zomyalelo), p - yinto yemihla imilinganiselo N, kwaye q - isiseko kwinkqubo yokufakwa (kulo mzekelo 2).

Asingabo bonke amanani ezincomekayo. Ukuze ukwahlula phakathi amanani akhabayo kunye navumelanayo, ikhompyutha ishiya indawo 1 bit uku encoder umqondiso. Apha zero ke dibanisa, kunye neyunithi - thabatha.

Ukusebenzisa le ngokwendlela yokunombola yenza kube lula ukuba computer ukusebenza ngamanani. Kungenxa yoko le nto ikhowudi yokubini jikelele xa computing iinkqubo.

encoding Binary kolwazi oye

alphabet ikhowudi neqela ngalinye zeros yayo kunye nabantwana. Okubhaliweyo siquka zabalinganiswa ezahlukeneyo: oonobumba (abakhulu abakhulu nabancinci), iimpawu izibalo kunye nezinye izinto ezahlukeneyo. I enkhowudingi lolwazi oye kufuna ukusetyenziswa lwamaxabiso ezisibhozo ezilandelelanayo lokubini ukusuka 00000000 ukuya 11111111. Ngaloo yinto enokwenzeka ukuguqula abalinganiswa ezahlukeneyo 256.

Ukunqanda uphazamiseko kwi khowudi yesicatshulwa, sebenzisa itafile ezizodwa amaxabiso ngomlinganiswa ngamnye. Bethule Latin alfabhethi, iimpawu izibalo kunye iimpawu injongo ekhethekileyo (umzekelo, €, ¥, ©, njalo njalo). Imiqondiso lokuphumla 128-255 encode oonobumba yesizwe eli lizwe.

Uku encoder iisimboli kufuna 1 8 bit memory. Ukuze lula podstchetov 8 amasuntswana ayalingana 1 byte, ngoko ke isithuba iyonke disk ulwazi itekisi ulinganiswa bytes.

Uninzi computer zixhotyiswe netafile esemgangathweni ASCII (iKhowudi eMiselweyo yaseMelika yoTshintshiselwano ngoLwazi). ezinye iitheyibhile zikwasetyenziswa, apho inkqubo ikhowudi inkcazelo oye yohlukile. Umzekelo, ezaziwayo enkhowudingi wokuqala ekuthiwa koi-8 (Code for yoTshintshiselwano ngoLwazi-8-bit), kwaye asebenze iikhompyutha UNIX OS. Iikhowudi SR1251 Table nazo zifumaneka ngokubanzi, nto leyo wadalwa ukuze isebenze kwisistim yeWindows.

esephepheni Binary sindo

Esinye isizathu sokuba esephepheni yokubini yindlela yendalo senkqubo data - yinto elula wayo xa usebenza iifayile audio. Nawuphi na umculo amaza isandi ezahlukeneyo awo kunye nezihlandlo oscillation. Ezi Useto luchaphazela umthamo kunye yitela.

Ukuze kwiprogram i isandi, ikhompyutha yahlula libe zizabelo eziliqela imiqathango, okanye "iisampuli". Inani leesampulu ezinjalo lingaba likhulu, ngoko kukho 65536 imidibaniso ezahlukeneyo amaqanda abo aba. Ngako oko, iikhompyutha mihla zixhotyiswe nge bit-16 ikhadi lesandi ukuba kuthetha ukusetyenziswa kwe-16 sebhithi uku encoder isampulu lencinibakazi yesandi.

Ukuze ukudlala i fayile audio, ikhompyutha kwiinkqubo ukulandelelana esetwe ngayo kwikhowudi yokubini kwaye idibanisa kwenye wave ngokuqhubekayo.

esephepheni chart

ulwazi Ujongano zinganikezelwa ngohlobo yemizobo, imizobo, imifanekiso okanye umbukiso kwi-PowerPoint. umfanekiso ngamnye wenziwa ngamachaphaza amancinci - pixels ezinokuthi zipeyintwe ngombala owahlukileyo. Umbala we pixel nganye ufakwe kwaye igcinwe, yaye ekugqibeleni sifumana umfanekiso opheleleyo.

Ukuba umfanekiso umnyama namhlophe, ikhowudi nganye pixel inokuba nokuba iyunithi okanye zero. Xa usebenzisa imibala emine, ikhowudi nganye kuzo luquka amanani amabini: 00, 01, 10 okanye 11. Ngokwalo mgaqo ukwahlula mfanelo nawuphi na umfanekiso processing. Ukwandisa okanye ukunciphisa ukugqama kwakhona abachatshazelwa yi inani lemibala ezisetyenziswayo. Kwimeko ilungileyo, ikhompyutha iyayahlula i malunga 16.777.216 imibala.

isiphelo

Kukho iindlela ezahlukeneyo lolwazi lwenkqubo, kuquka encoding yokubini enempumelelo kakhulu. Kuphela weesimboli ezimbini - 0 no 1 - computer ngokulula ufunda iifayile ezininzi. Esikhoyo isantya processing liphezulu kakhulu kunokuba kusetyenziswa, umzekelo, nodweliso lwenkqubo i inkqubo wokugqibela. Elula le ndlela yenza kube ziluncedo na ubugcisa. Kungenxa yoko le nto ikhowudi yokubini kubantu bonke abahlobo bakhe.
