Izinhlamvu Zokulawula Ikhodi ye-ASCII
Impela uke wazibuza ukuthi umhlaba wekhompyutha usebenza kanjani, awu, uyinkimbinkimbi kakhulu kunalokho esikucabangayo futhi ngemuva kwemisebenzi elula njengokubhala eshidini le-Word noma ukuthumela idokhumenti ukuthi iphrinte, kunezinqubo ezenzeka kuma-microsecond afakwe ikhodi ngaphambilini.
I-American Standard Code for Information Exchange noma i-ASCII yesifinyezo sayo ngesiNgisi, isethi yezinhlamvu noma izimpawu ezisuselwe kusiLatini kuya -njengoba igama layo lisho- ukushintshanisa ulwazi futhi isebenzise ngendlela efanele.
Ithebula lezinhlamvu zokulawula nezimpawu zekhodi ye-ASCII
Yiziphi izinhlamvu zokulawula ikhodi ye-ASCII?
Zikhona, i Ikhodi ye-ASCII izinhlamvu eziphrintekayo okuyizona esizibonayo kanye nezinhlamvu ezilawulayo ezikhona labo abathumela ulwazi ukwenza umsebenzi, njengokuthumela ifayela ukuze liphrintwe, isibonelo.
Iqoqo lezinhlamvu nezimpawu zalezi zinto ezimbili ziphumela kokuthile okubizwa ngokuthi Izinhlamvu zekhodi ye-ASCII enwetshiwe futhi ziyizinhlamvu “ezengeziwe” esizisebenzisa nsuku zonke, njengokuthi: ¡,',?,-,€,#, njll.
Ngokuqonda lokhu, singase sithi izinhlamvu zokulawula ikhodi ye-ASCII akuzona esizibonayo, kodwa yizo esizibonayo. zenziwa ngaphakathi ohlelweni ukuze zikhiphe umyalo.
Izinhlamvu zokulawula ikhodi ye-ASCII nezimpawu zavela ukuze zinikeze isisombululo senkinga yendawo yonke, futhi yilokho Eminyakeni eminingi edlule, ulwazi bekungelula ukudlulisa njengoba kwenzeka manje.
Ngokuya ngekhompyutha esetshenziswa abasebenzisi, isistimu yokusebenza iyahlukahluka, futhi ngayo, ifomethi amafayela angabiwa ngayo iyahlukahluka, okungukuthi, ifayela alibukekanga noma lifunde ngendlela efanayo kwenye ikhompuyutha njengoba lenza kwenye.
Lokhu kwenzeka ngoba ikhompuyutha ngayinye yayinekhodi ehlukile, masikhumbule ukuthi, ekuqaleni kwenkathi yekhompyutha, isidingo sasingekho njengoba sinjalo namuhla futhi bekunamathuba amaningi okufaka amatafula, izimpawu, amakhodi nokunye ngakunye.
Njengoba isidingo semishini kagesi sikhula futhi isidingo sokwabelana ngolwazi sikhula cishe, i Ikhodi ye-ASCII.
Ngale ndlela, kwakungenzeka ukunikeza isisombululo senkinga, eye yathuthukiswa.
Izinhlamvu zokulawula amakhodi ze-ASCII zigcinwe ngamakhodi okuqala angamashumi amathathu nambili, anenombolo 0 kuya ku-31; bezingahloselwe kusukela ekuqaleni ukumela ukwaziswa okuphrintekayo, kodwa ukulawula amadivaysi.
Zisetshenziselwani?
Izinhlamvu zokulawula ikhodi ze-ASCII zisetshenziselwa ukunikeza imiyalo, okungukuthi, ukwenza imiyalo futhi ukwazi ukukhiqiza kabusha isenzo noma amatafula nezimpawu.
Isibonelo, zonke izenzo esizenzayo ngekhompyutha, inikezwe kumathebula uphawu oluhambisana nezinhlamvu zokulawula ikhodi ye-ASCII, njengoba, uma isenzo "sokususa" sinikezwe ikhodi engu-125, njalo uma ucindezela inkinobho yokususa, le nombolo iphinde ikhiqizwe kusukela kukhiye wokulawula ikhompyutha, futhi lokho okukhethayo kuyasuswa.
Esinye isibonelo ukuphrinta noma iyiphi idokhumenti noma isithombe, ngesikhathi lapho sikhetha khona inketho yokuphrinta ikhipha ikhodi ehambisana nalokho okwabelwe kuthebula lohlamvu Ukulawulwa kwekhodi ye-ASCII.
Ngale ndlela, izinhlamvu zokulawula amakhodi ze-ASCII zavela zaze zaba yindawo yonke futhi cishe wonke amadivaysi ayenazo.
Zisetshenziswa kanjani izinhlamvu zokulawula ikhodi ye-ASCII?
Kunetafula lapho unikezwe khona ikhodi ehambisana nezinhlamvu zokulawula ikhodi ye-ASCII.
Eqinisweni, usebenzisa lezi zinhlamvu zokulawula ikhodi ye-ASCII nsuku zonke, isibonelo, uma usebenzisa uhlamvu lwe-ESC ukuphuma kumodi yokudlala yesikrini esigcwele ku-YouTube.
Noma futhi, lapho usebenzisa ukhiye we-TAB, ophethe ukuhambisa ikhesa emugqeni ubheke endaweni echazwe ngaphambilini kulesi simo, futhi ngokuvamile ibheke endaweni evundlile, nakuba ngendlela efanayo, kukhona i-VT, okuyithebhu eqondile.
Emafasiteleni
Kusistimu yokusebenza ye-Windows, ungase ukwazi ukufaka imiyalo okungeyona eyekhibhodi ngokusebenzisa nje imephu yezinhlamvu ngokuchofoza inkinobho yokuqala.
Uma kuvela iwindi, uzothayipha "i-charmap" endaweni yokusesha lapho futhi uzoyenza Chofoza kumphumela ohlongozwayo.
Ngemva kokuqeda lezi zinyathelo, kuzovela imephu yezinhlamvu esikrinini, egcwele zonke izici ezitholakalayo, vele ukhethe eyodwa ofuna ukuyiqhuba futhi yikho nje.
KuMac
Uma ukudivayisi enesistimu yokusebenza ye-iOS efana ne-Macs, sizosebenzisa izinqamuleli zekhibhodi.
Kukhona eziningana futhi kuzohluka kuye ngokuthi yini oyifunayos, ngokwesibonelo, ukuze uphume ngokuphelele kunoma yiluphi uhlelo ku-Mac uzodinga umyalo wokuphuma, kungaba ngesinqamuleli noma ngemenyu kuhlelo lokusebenza ngoba nge-X ebomvu ayiphumi ngokuphelele:
- Ukuze uphoqe ukuyeka noma yiluphi uhlelo lokusebenza olungaphenduli, bamba i-Command + Shift + Option + Esc imizuzwana emithathu.
- Ukuvala noma yiliphi iwindi elisebenzayo olisebenzisayo sebenzisa i-Command + W
- Ukuvala wonke amawindi avuliwe kuhlelo lokusebenza, sebenzisa i-Option + Command + W
- Ukuze uvule ithebhu entsha kunoma yisiphi isiphequluli, sebenzisa i-Command + T
- Ukuze uvule idokhumenti entsha, cindezela u-Command + N
- Ukufihla iwindi lohlelo olusebenzisayo, cindezela u-Command + H
- Ukuze ufihle wonke amawindi ohlelo lokusebenza futhi ubuyele esikrinini sangemuva, sebenzisa i-Command + Option + H
- Ukuze ubonise ukuqalisa kabusha, ingxoxo yokulala noma yokuvala shaqa cindezela u-Ctrl + Eject
- Ukwenza isibonisi silale cindezela u-Shift + Control + Eject
- Ukuze ulalise ikhompuyutha cindezela u-Command + Alt + Eject
- Ukugcina noma ukuvala zonke izinhlelo zokusebenza futhi ngemva kwalokhu, qala kabusha i-MAC, sebenzisa i-Command + Control + Eject
- Ukuze uphume ku-akhawunti yakho yomsebenzisi ye-OS X, sebenzisa i-Command + Shift + Q, nakuba lokhu kuzocela ukuqinisekiswa.
Kwi-Linux
Ukuyisebenzisa ohlelweni lokusebenza lwamahhala, olufana ne-Linux, inqubo imvamisa ihluke kancane ngoba izinhlamvu zokulawula ziyashintsha futhi kufanele. yazi ikhodi ye-hex okudingayo, ngoba ngokujwayelekile ezinye izinhlelo zokusebenza ezimbili zangaphambilini zisebenzisa amadesimali.
Ukuze uvule iwindi ukuze ubhale enye yezinhlamvu zokulawula, kufanele ucindezele izinkinobho ze-Ctrl + Shift + U ukuze ngemva kokuvula ibha yokusesha ufake ikhodi ye-hexadecimal.
Isibonelo, ukuqalisa isibali sesayensi kutheminali ye-Windows ikhodi yedesimali ithi 126, uma siyiguqulela ohlelweni lwe-hexadecimal sithola u-7E, ngakho sithayipha u-7E enjinini yokusesha bese sishaya u-Enter.
Lona bekuwumsebenzi lapho izigidi zabahleli bezinhlelo bezibandakanyeka, ukuze uhlelo kanye ne Izinhlamvu zokulawula ikhodi ye-ASCII kube ulimi olufanayo emhlabeni wonke.
