Encoding uye decoding chinyorwa ruzivo

Kana iwe kumanikidza kiibhodhi kiyi pakombiyuta anogamuchira chiratidzo ari muchimiro binary nhamba, iyo inogona kuwanikwa inopangidza petafura remitemo - womukati kumiririrwa vatambi vari PC. Standard pose tenda tafura ASCII.

Zvisinei, vashomanana vanoziva zvinotaurwa yeEncoding uye decoding, unofanirawo kunzwisisa kuti mashoko iri kombiyuta yako. Somuenzaniso, kuti kuchengeta imwe binary chiratidzo yemagetsi kombiyuta asarudza 1 byte, i.e. 8 matomu. Sero Izvi zvinogona kuva maviri chete netsika: 0 uye 1. Zvakaratidza kuti umwe byte unokubvumira encrypt ari 256 vatambi siyana, nokuti inhamba anofambidzana munogona. mubatanidzwa izvi uye ndivo kiyi chikamu tafura ASCII. Somuenzaniso, tsamba S iri coded sezvo 01010011. Kana unopfuurira pamusoro keyboard, pane Coding uye decoding pamusoro data, uye tinowana kuti zvinotarisirwa mugumisiro pamadziro.

Hafu mureza ASCII tafura rine Codes nenhamba, kuzvidzora vatambi tsamba Chirungu. Chimwe chikamu chacho Rakazara mavanga yenyika, ekunyebera mavara uye zviratidzo dzisina chokuita masvomhu. Zviri pachena kuti munyika dzakasiyana, chikamu ichi tafura zvichava zvakasiyana. kana kupinda digits vari kutendeuka kuva binary kukarukureta gadziriro maererano pfupiso.

Encoding nhamba

In binary notation, izvo zviri kushingaira kushandisa makombiyuta, pane chete digits miviri - 0 uye 1.

Matanho vaite binary gadziriro nhamba kudzidza binary svomhu. Vazhinji mitemo dzinokosha kwemasvomhu remapazi nenhamba dzakadaro kuramba akakodzera.

Mienzaniso yeEncoding uye decoding nhamba

We zvamaronga kuti funga 2 yeEncoding nzira nechipi 45. Kana izvi zvaitika mukati chinyorwa chinyorwa, ipapo mumwe nomumwe wayo chinoumba vachanzi encoded maererano ASCII mwero patafura 8 matomu. Four dzokai kuna 01000011, uye shanu - kusvikira 01.010.011.

Kana nhamba 45 rinoshandiswa nokuda kukarukureta, chichagamuchirwa munyaya nzira chaiyo rokutendeutsa masere ikakuruma binary remitemo 001 011 012, iyo inodiwa okuchengetera ndiyo chete 1 byte.

Coding mashoko kwakajeka

Kuwedzera monochrome mufananidzo pamwe rinokudza girazi, uchaona kuti une vakawanda Dots duku kuti vaumbe muenzaniso wakakwana. unhu nomumwe mufananidzo mumwe uye Linear Coordonatele upi pfungwa kunogona kuratidzwa dziri nhamba. Naizvozvo, kuti bitmap yeEncoding inobva binary code, akachinja kuti pakuva ruzivo kwakajeka.

Black uye chena mifananidzo - mubatanidzwa pfungwa yakasiyana noruvara vachena, kureva, nokupenya neimwe mufananidzo pfungwa akatsunga masere-ikakuruma binary nhamba. Pfungwa yacho manyowa ane zvemasanga gradient pamusoro dzinokosha zvinoriumba - ndiyo nheyo iyi, sezvo Coding kwemashoko ari kwakajeka. Decoding mifananidzo rinowanikwa saizvozvo, asi zvisizvo.

Kana kuwedzera dzinokosha mavara matatu: mutema, tsvuku uye zvitema, chero dzinongoitika mumvuri chingawanikwa tichibatanidza gradients izvi. Izvi Coding gadziriro anonzi RGB. Kana maviri nezvina matomu kuti encrypt munhu hwakajeka mufananidzo kutendeuka muoti inonzi zvizere ruvara.

Mavara All dzinokosha juxtaposed noruvara kuti mukwanisi nechigadziko pfungwa, zvichiita chena. Zvimwe ruvara - iri gradient inoumbwa Verengai mamwe mavara dzinokosha. Emit yero, magenta, uye cyan nopindirana mavara.
