Nei zvakasikwa binary yeEncoding? zvirongwa nzira

The kombiyuta kurongedza mashoko yakawanda mashoko. Audio mafaira, mifananidzo, chinyorwa - imi mose vanoda kutamba kana kuratidza. Sei binary Coding inzira kwose date zvirongwa chero michina michina?

Chii vakasiyana Coding encryption?

Kazhinji vanhu vanobva vangofunga pfungwa "Coding" uye "encryption", kana iri chokwadi vane nedudziro. Saka, encryption ndiwo muitiro rokutendeutsa mashoko kuitira kuvanza nayo. Decrypt kakawanda zvingaitwa nemunhu akachinja chinyorwa, kana zvikuru akadzidzisawo vanhu. Coding rinoshandiswa kuti kubudiswa mashoko uye shungu kushandiswa kwaari. Coding tafura zvakafanana inowanzoshandiswa, avanoziva wose. It inovakwa kupinda kombiyuta yako.

binary Coding musimboti

Binary yeEncoding kunobva pakushandisa maviri chete zviratidzo - 0 uye 1 - nokuti processing ruzivo aishandiswa dzakasiyana namano. Zviratidzo izvi zvinonzi binary digits, Chirungu - binary digit, kana napaduku pose. Imwe neimwe zviratidzo zviri binary remitemo anopindura ndangariro kombiyuta kuti 1 wedzeredzei. Sei binary Coding inzira kwose processing mashoko? Chokwadi chokuti kombiyuta nyore kugadzirisa vatambi vashoma. Kubva ichi zvinoenderana uye kunyatsoshanda pamusoro PC: kashoma dzichipfekeka mabasa zvakakodzera kuita mudziyo, dzakanga kumhanya uye unhu basa.

binary Coding musimboti chinowanikwa kwete chete mapurogiramu. Tiine alternation kuti rinyerere uye vataura Drum anorova vaPolynesia nekufambisa mashoko kune mumwe. A yakafanana zvinoshandawo muna Morse code, uko refu uye pfupi ruzha zvinoshandiswa kuparadzira mashoko. "Telegraphic arufabheti" kushandiswa nhasi.

Where kushandisa binary yeEncoding?

The binary Coding mashoko ari kombiyuta rinoshandiswa pose pose. Mumwe faira, ingava nziyo kana chinyorwa kuti zvinofanira chiite kuti aizogona nyore avakaita uye kuverenga. binary Coding maitiro runobatsira kushanda zviratidzo uye nhamba, okuteerera, Graphics.

Binary yeEncoding nhamba

Zvino nhamba kombiyuta anomiririrwa mune coded chimiro, isinganzwisisiki kune avhareji munhu. Kushandiswa Arabic sezviverengo, sezvo isu kufungidzira, nokuti magadzirirwo seisingashandi. Chikonzero ichi ndicho chikonzero kurongera rakasiyana nhamba kune mumwe nemumwe zvokuita panguva zvisingabviri.

Kune ukanyora zviviri: positional uye nepozitsionnyh. Nepozitsionnyh hurongwa kunobva pakushandisa tsamba Latin uye yaizivikanwa kwatiri muchimiro pamusoro nenhamba Greek. Ichi kutsikisa nzira rakanyatsojeka yakaoma kunzwisisa, saka, yakasiyiwa.

Positional nhamba ezvinhu kushandiswa nhasi. Izvi zvinosanganisira binary, grade, octal uye hexadecimal Coding kunyange mashoko.

Grade Coding maitiro tinoshandisa muupenyu hwezuva nezuva. Zviri yekushandisa kwatiri Arabic sezviverengo, izvo zvinonzwisisika vose. Binary yeEncoding siyana nhamba vachishandisa chete razero uye mumwe.

Integers vari kutendeukira binary Coding kuburikidza kupatsanura pavo 2. zvichiguma kukwana zvakare rakakamurwa muzvikamu zviviri, kusvikira pakupedzisira 0 kana 1. Somuenzaniso, nhamba 123 ₁₀ binary notation kunogona kumiririrwa mu fomu ₂ 1111011. A anoverengeka October ₂₀ achaonekwa sezvo 10100 _2.

Maindex 10 uye 2 vari runotaurwa azvaitwa binary uye grade zviverengero Coding hurongwa. binary Coding chiratidzo inoshandiswa husava nokushanda tsika dzinotaurwa zvakasiyana nhamba enyika.

Zvirongwa mitoo grade nhamba inotorwa "zvinoyangarara pfungwa". Kuti zvakanaka uchatamisa kukosha kubva grade kusvika binary Coding hurongwa kushandisa nzira N = M X qp. M - ndiye mantissa (pasina kutaura chero murayiro), peji - ndiwo murayiro zvinokosheswa N, uye Q - chawo Coding system (mu iyi 2).

Havasi nhamba zvose akanaka. Kuti asiyanise zvakanaka nezvakaipa nhamba, kombiyuta anosiya nzvimbo 1 ikakuruma kuti encode chiratidzo. Pano razero ari plus uye chikwata - kubvisa.

Muchishandisa ichi vaverengwa hurongwa zvinoita nyore kuti kombiyuta kushanda nenhamba. Ndokusaka binary Coding pose apo kadambari pezvakaitwa.

Binary yeEncoding unonyatsoratidza kuti mashoko acho mashoko

Mumwe arufabheti coded unhu akagadzirwa zeros ayo uye vaya. The chinyorwa chine dzakasiyana kutaurwa: tsamba (uppercase uye lowercase), svomhu zviratidzo uye dzimwe tsika dzakasiyana-siyana. The yeEncoding unonyatsoratidza kuti mashoko acho mashoko zvinoda kushandiswa masere anotevedzana binary tsika kubva 00000000 kusvika 11111111. Saka zvinoita kutendeutsa 256 vatambi siyana.

Kuti tidzivise kuvhiringidzika ari yeEncoding chorugwaro, shandisa chaiyo patafura netsika mumwe hunhu. Ivo kupa Latin arufabheti, svomhu zviratidzo uye zviratidzo chinangwa chinokosha (somuenzaniso, €, ¥, ©, etc.). Zviratidzo penguva 128-255 encode munyika National arufabheti.

To encode zviratidzo kunoda 1 8 ikakuruma ndangariro. Kurerutsa podstchetov 8 matomu vakaenzana 1 byte, saka yose dhisiki nzvimbo chinyorwa ruzivo unotaurwa bytes.

makombiyuta Most pachako takashongedzerwa ane mwero tafura ASCII (American Standard Code nokuda Information Kukurudzirana). dzimwe matafura anoshandiswawo, umo Coding mamiriro zvakawedzerwa mashoko akasiyana. Somuenzaniso, mashoko okutanga kuvazivisa unhu yeEncoding rinonzi Koi-8 (Code nokuti Information Kukurudzirana 8-yati), uye zvinoshanda pamusoro Unix Os makombiyuta. Table SR1251 Codes unowanikwa zvikuru, hwakasikwa nokuda Windows kushanda hurongwa.

Binary Coding mazwi

Chimwe chikonzero nei binary Coding inzira kwose date zvirongwa - raro nyore kana tichishanda okuteerera. mumhanzi Chero riri ruzha kunosiyana amplitude uye kakawanda oscillation. Kurongwa izvi zvinokanganisa vhoriyamu uye kukwirira kwenzwi.

Kuti chirongwa kurira chinozunguzirwa, kombiyuta rinokamukana kuva akawanda zvikamu conditionally, kana "ivhu". Kuwanda ivhu dzakadaro angava makuru, saka kune 65536 akasiyana mubatanidzwa Kwemagandanga Achishandisa Kombiyuta. Saizvozvowo, makombiyuta ano vari vakapakata 16-ikakuruma mutsindo kadhi rinoreva kuti kushandiswa 16 binary digits kuti encode nzwisa inzwi wave.

Kuridza maCD faira, kombiyuta kurongedza mashoko chiite kutevedzana kwezviitiko binary remitemo uye rinoabatanidza munzvimbo imwe chichiitwa wave.

Coding machati

Graphical mashoko anogona kupiwa muchimiro Graphics, Madhayagiramu, mifananidzo kana Slideshow muna PowerPoint. mufananidzo Mumwe rinoumbwa Dots diki - pixels kuti inogona kupendwa yakasiyana ruvara. Ruvara neimwe Pixel ari encoded uye inochengetwa, uye pakupedzisira tinoona kuwana mufananidzo zvizere.

Kana mufananidzo rasviba uye chena, mumwe Pixel yekubvuma vangava chikwata kana razero. Kana uchishandisa zvina mavara, bumbiro remitemo neimwe ine nhamba mbiri: 00, 01, 10 kana 11. Maererano nenheyo iyi kusiyanisa unhu kwemifananidzo kugadzira. Wedzerai kana kuderera Nokupenya iri kukanganiswa nokuwanda mavara akashandiswa. In yakanakisisa nyaya, kombiyuta chinosiyanisa vanenge 16.777.216 mavara.

mhedziso

Pane nzira dzakasiyana mapurogiramu mashoko, kusanganisira binary yeEncoding ndiyo inonyatsobudirira. na chete zviratidzo zviviri - 0 1 - kombiyuta nyore anoverenga mafaira akawanda. Pakazoti kubudiswa nokukurumidza kwakakwirira zvikuru kupfuura kuti kushandiswa Somuenzaniso, zvirongwa ari grade hurongwa. Kujeka Nzira iyi inoita dzetsika dzemagariro chero rwokugadzira. Ndokusaka binary Coding pose vezera ake.
