Ngawaphi ikhadi lesandi?

Ngoku umsindo amakhadi computer zibe yinxenye eqhelekileyo kwiinkqubo zekhompyutha. Abasebenzisi abaninzi makhwelo musa nakubona ukuze kubekho ezinye indlela. Kodwa kwiminyaka elishumi elinesihlanu kuphela ethile eyadlulayo, zonke umnini ikhompyutha, owayefuna ukuva inkqubo ayincedi ukukrikriza inkqubo isithethi, kwaye isandi lokwenene (nkqu namazwi abantu kwizicelo yemultimedia!), Kwanyanzeleka ukuba bathenge zombini odiyo. Ngaphezu koko, ukufunda amakhadi isandi efunekayo Itshaneli DMA kunye ziphazamise uqwalaselo siseko, ukhetho ngokutsho parameters ibhasi kwi iifayile imithi. Ukongeza, neendlela zokuqala zibiza imali eninzi kakhulu. Ngenxa yoko, amakhadi isandi sele ifakiwe kuphela midlalo. Yaye yintoni na imeko ngoku?

Solutions ezakhayo

Zonke ekhoyo amakhadi isandi nga zohlulwa ngokwendidi ezintathu eziphambili:

• uhle ekhethekileyo. Mhlawumbi oku kubizwa ngokuba Classic. Eli khadi i omncinane PCB kunye ezibekwe phezu kwawo kumacandelo elektroniki kunye iqela labantu ofowunelana nabo utyhala ukudibanisa kwi isinxibelelanisi efanelekileyo motherboard ibhasi. Ekubeni zifakwa kwinkqubo unit le, kodwa ngamanye amaxesha kuthiwa zangaphakathi;
• Ibephakathi (eyayifakwe, integrated). Loo modeli soldered ukuya chipset motherboard kunye nezinto igiza abangabancedani eziliqela, nto leyo owenza yonke imisebenzi esisiseko ye ikhadi lesandi classical;
• Bangaphandle. Zizixhobo kakhulu ukuba sidityaniswe mazibuko USB.

Iimpawu nezisombululo eyakhelwe-ngaphakathi

Kaninzi abantu ukude kuphela zingagilani kunye bokuqonda isandi computer, umbuzo ophakamayo ngomahluko iluncedo amakhadi yesandi. Ngapha koko, yonke enye, imodeli iimpawu, akunguye umahluko kubalulekile. Izisombululo ubuncinane eninzi thaca iimaphu eyakhelwe-ngaphakathi. Ixabiso lokwenene chip isandi sivela-1 ukuya $ 10 (ngokuba kuthelekiswa, oyena mncinane kumnombo obubobu ikhadi lesandi Asus Xonar abenzi ezifundisa phantse $ 40). Ukongeza, isandi sokuqala-class uyazi ukuba ngenxa yamalungiselelo olwandeleyo yeekhomponenti kwi motherboard kuvela baya- nokuphazamiseka zombane efanayo ezichaphazela "ntumbuluko" umdlalo. Nangona oku kusombululeka ngokuthi ilahla analog digital, le yokugqibela akufanelekanga ukusebenzisa i amakhadi afanayo kangako. Kwaye ekugqibeleni, simele sikhumbule ukuba uninzi lwemisebenzi ukwenza abaqhubi umsinga processing ukuba ikhadi lakho sandi usebenzisa amandla of the CPU. Ngoko ke, ikhadi eyakhelwe-ngaphakathi sisisombululo elikhulu umntu akafuni ukuchitha imali kuthengwe iadaptha eyahlukileyo ezirekhodiweyo, kwaye alizithathi umculo wenene umthandi.

Bokuqonda uhle ekhethekileyo

Okwangoku, i izisombululo ifanelekileyo PCI-Express bus. Ezo iimephu, nkqu avareji yeendleko, sele ziqulathe "kwibhodi" umqhubekekisi ezinikeleyo yinxalenye eyenza flow lweenkcukacha okwehlisa. Amaxesha amaninzi imifuziselo ezahlukene ineenketho ezininzi (umzekelo, ASIO inkxaso) ngaphezu kunoogxa eyakhelwe-ngaphakathi. umgangatho welizwi iphezulu kakhulu ngokuqhelekileyo ngaphezu koko kwezi izisombululo ekwinqwelo. Xa ukhetha, kuba uyazi ukuba nayiphi na ikhadi ezongezelelweyo ngaphakathi ityala mandundu umoya kwegazi, ngokumandla ngokwaphula ubushushu. Ukongeza, ukusetyenziswa kwamandla ingaphezulu kunolo iimaphu eyakhelwe-ngaphakathi.

amakhadi sound lwangaphandle

Ezi zixhobo lungahlulwa-hlulwa ibe ngamaqela amabini: i cheap, enyanisweni, amele chip efanayo izisombululo ekwinqwelo, kodwa 'ehleli "kwi-USB ibhasi; kwakunye amakhadi zobungcali isiphelo ophezulu.
