ASCII Code Control Characters
Ngokuqinisekileyo uye wazibuza malunga nendlela ihlabathi lekhompyuter elisebenza ngayo, ewe, lintsonkothe ngakumbi kunokuba sicinga kwaye emva kwemisebenzi elula njengokubhala kwiphepha leLizwi okanye ukuthumela uxwebhu ukuprinta, kukho iinkqubo ezenzeka kwii-microseconds ezikhowudwe ngaphambili.
IKhowudi yoMgangatho waseMelika yoTshintsho loLwazi okanye i-ASCII yesifinyezo sayo kwisiNgesi, yiseti yeempawu okanye iisimboli ezisekelwe kwisiLatini ukuya -njengoko igama layo litsho- ulwazi lotshintshiselwano kwaye luphumeze ngokufanelekileyo.
Uluhlu lwabalinganiswa bolawulo kunye neempawu zekhowudi ze-ASCII
Zeziphi iimpawu zolawulo lwekhowudi ye-ASCII?
Zikhona, i ASCII code printable abalinganiswa zeziphi ezo sinokuzibona kunye nabalinganiswa bolawulo abakhoyo abo bathumela ulwazi ukwenza umsebenzi, njengokuthumela ifayile ukuprinta, umzekelo.
Isethi yabalinganiswa kunye neesimboli zezi zimbini zikhokelela kwinto ebizwa ngokuba yi abalinganiswa ikhowudi ASCII eyandisiweyo kwaye ngabalinganiswa "abongezelelweyo" esibasebenzisa yonke imihla, abanje: ¡,',?,-,€,#, njl.
Ukuqonda oku, sinokuthi ke ikhowudi yokulawula ikhowudi ye-ASCII ayizona esizibonayo, kodwa thina zenziwa ngaphakathi kwindlela yokwenza umyalelo.
Iimpawu zokulawula ikhowudi ye-ASCII kunye neempawu zavela ukunika isisombululo kwingxaki yendalo yonke, kwaye oko Kwiminyaka emininzi edlulileyo, ulwazi bekungekho lula ukuhambisa njengokuba kunjalo ngoku.
Ngokuxhomekeke kwikhompyuter esetyenziswa ngabasebenzisi, inkqubo yokusebenza yahluka, kwaye nayo, ifomathi ekunokwabelwana ngayo iifayile, oko kukuthi, ifayile ayizange ijonge okanye ifunde ngokufanayo kwikhompyuter enye njengoko yenzayo kwenye.
Oku kwenzeka ngenxa yokuba ikhompyuter nganye yayibhalwe ngokwahlukileyo, masikhumbule ukuba, ekuqaleni kwexesha lekhompyuter, imfuno yayingeyona nto ikhoyo namhlanje kwaye. bekukho amathuba amaninzi okudibanisa iitafile, iisimboli, iikhowudi kunye nabanye ngabanye.
Njengoko imfuno yezixhobo zombane isanda kwaye nemfuno yokwabelana ngolwazi ikhula, i Ikhowudi ye-ASCII.
Ngale ndlela, kwakunokwenzeka ukubonelela ngesisombululo kwingxaki, eye yaphuhliswa.
Iimpawu zokulawula ikhowudi ye-ASCII ziye zagcinwa kunye neekhowudi zokuqala ezingamashumi amathathu anesibini, ezibalwe kwi-0 nge-31; bezingenzelwanga kwasekuqaleni ukumela ulwazi olushicilelweyo, kodwa ukulawula izixhobo.
Zenzelwe ntoni?
Iimpawu zolawulo lwekhowudi ye-ASCII zisetyenziselwa ukunika imiyalelo, oko kukuthi, ukwenza imiyalelo kwaye ube nako ukuvelisa kwakhona intshukumo nokuba ziitheyibhile kunye neesimboli.
Umzekelo, yonke into esiyenzayo ngekhompyuter, inikwe kwiitheyibhile isimboli ehambelana neempawu zokulawula ikhowudi ye-ASCII, ekubeni, ukuba isenzo "sokucima" sinikwe ikhowudi ye-125, rhoqo xa ucinezela iqhosha lokucima, le nombolo iphinda iphinde ivele kwisitshixo kulawulo lwekhompyutheni, kwaye into oyikhethayo iyacinywa.
Omnye umzekelo kukuprinta naluphi na uxwebhu okanye ifoto, ngeli xesha sikhetha ukhetho lokuprinta yenza ikhowudi ehambelana noko kwabelwe kwitheyibhile yomlinganiswa Ulawulo lwekhowudi ye-ASCII.
Ngale ndlela, oonobumba bolawulo lwekhowudi ye-ASCII bavela bada baba yindawo yonke kwaye phantse zonke izixhobo zinabo.
Zisetyenziswa njani iimpawu zolawulo lwekhowudi ye-ASCII?
Kukho itafile apho unikwe ikhowudi ehambelana neempawu zokulawula ikhowudi ye-ASCII.
Enyanisweni, usebenzisa ezi ASCII ikhowudi abalinganiswa yokulawula yonke imihla, umzekelo, xa usebenzisa unobumba we-ESC ukuphuma kwimowudi yokudlala yesikrini esigcweleyo kuYouTube.
Okanye kwakhona, xa usebenzisa iqhosha le-TAB, elijongene nokuhambisa ikhesa kumgca ukuya kwindawo echazwe ngaphambili kule meko, kwaye ngokubanzi ukuya kwindawo ethe tye, nangona ngendlela efanayo, kukho i-VT, ethe nkqo isithuba.
Kwiifestile
Kwinkqubo yokusebenza yeWindows, usenokukwazi ukufaka imiyalelo engeyiyo eyebhodibhodi ngokusebenzisa imephu yeempawu ngokucofa iqhosha lokuqala.
Nje ukuba kuvele ifestile, uya kuchwetheza "i-charmap" kwindawo yokukhangela apho kwaye uya Cofa kwisiphumo esicetywayo.
Emva kokuba ugqibezele la manyathelo, imephu yomlinganiswa iya kuvela esikrinini, igqibe yonke into ekhoyo, khetha nje leyo ufuna ukuyiqhuba kwaye yiloo nto.
KwiMac
Ukuba ukwisixhobo esinenkqubo yokusebenza ye-iOS efana neeMacs, siza kusebenzisa iindlela ezimfutshane zebhodi yezitshixo.
Zininzi kwaye ziya kwahluka ngokuxhomekeke kwinto oyifunayos, umzekelo, ukuphuma ngokupheleleyo kuyo nayiphi na inkqubo kwiMac uya kufuna umyalelo wokuPhuma, nokuba yindlela emfutshane okanye ngemenyu ekwisicelo kuba nge-X ebomvu ayiphumi ngokupheleleyo:
- Ukuze unyanzelise ukuyeka naluphi na usetyenziso olungaphenduliyo, bamba Umyalelo + Shift + Option + Esc imizuzwana emithathu.
- Ukuvala nayiphi na ifestile esebenzayo oyisebenzisayo sebenzisa Umyalelo + W
- Ukuvala zonke iifestile ezivuliweyo kusetyenziso, sebenzisa uKhetho + Umyalelo + W
- Ukuvula ithebhu entsha nakwesiphi na isikhangeli, sebenzisa Umyalelo + T
- Ukuvula uxwebhu olutsha, cofa Umyalelo + N
- Ukufihla ifestile yesicelo osisebenzisayo, cofa Umyalelo + H
- Ukufihla lonke usetyenziso olukhoyo windows kwaye ubuyele kwiscreen esingasemva, sebenzisa Command + Option + H
- Ukubonisa ukuqalisa kwakhona, lala okanye uvale incoko yababini cofa Ctrl + Eject
- Ukubeka umboniso ukuba ulale cofa uShift + Control + Eject
- Ukubeka ikhompyuter ukuba ilale cofa Command + Alt + Eject
- Ukugcina okanye ukuvala zonke izicelo kwaye emva koku, qalisa kwakhona i-MAC, sebenzisa Command + Control + Eject
- Ukuphuma kwiakhawunti yakho yomsebenzisi we-OS X, sebenzisa uMyalelo + Shift + Q, nangona oku kuya kucela ukuqinisekiswa.
Kwi-Linux
Ukuyisebenzisa kwinkqubo yokusebenza yasimahla, efana neLinux, inkqubo iqhele ukuba yahluke kancinane kuba iimpawu zolawulo ziyatshintsha kwaye kufuneka. yazi ikhowudi ye-hex okufunayo, kuba ngokwesiqhelo ezinye iinkqubo ezimbini ezidlulileyo zisebenzisa idesimali.
Ukuze uvule ifestile ukuze ubhale omnye wabalinganiswa bolawulo, kufuneka ucinezele i-Ctrl + Shift + U izitshixo ukwenzela ukuba emva kokuba ibha yokukhangela ivula ufake ikhowudi ye-hexadecimal.
Umzekelo, ukuqalisa i-science calculator kwi-terminal ye-Windows ikhowudi yesishumi yi-126, ukuba siyiguqulela kwi-hexadecimal system sifumana u-7E, ngoko ke sichwetheza ngo-7E kwi-injini yokukhangela kwaye sibethe u-Enter.
Lo ibingumsebenzi apho izigidi zabaprogram bezibandakanyeka, ukuze inkqubo kunye ne Iimpawu zokulawula ikhowudi ye-ASCII ibe lulwimi olunye jikelele.
