Imposiso IO kunye nokupheliswa kwayo

Xa iinkqubo zokusebenza, inkampani "Microsoft" Impazamo igalelo-output kwisixhobo kuthetha ukuba inkqubo ethile kwakukho ubunzima ekufundeni okanye data ukonga kwisixhobo yokugcina. Ukuba oku intonga, ngoko lo myalezo kubonakala ngexesha ukusetyenziswa kwazo ngokusebenzisa umfundi khadi, okanye xa uzama ukufikelela nayiphi na ifayile. Amaxesha amaninzi imposiso IO ibonisa ukuba esi sixhobo kufuneka kufakwe. Nangona kunjalo, unga zama ukuvuselela data yakho, nkqu kubuyela ebomini yogcino.

Masiqonde kuqala kutheni oku kuyenzeka. Umonakalo diski okanye flash drive ayikwazi ngu ntshikilelo ngoomatshini (umz, ukuwa, ukothuka, njalo njalo). Ukuba phosakeleyo elifakwe okanye isuswe ikhadi, ahlole ngenyameko oko ngokukhubazeka ezicacileyo yeqela qhagamshelana okanye emzimbeni. Kudla ngokuthi ukuba ungumgqithi iqokobhe ebuyiselweyo, imephu iqalisa ukusebenza kwakhona. Emva koko uya kuba nako ukubuyela ulwazi. Emva oku kufuneka balahle elibi drive. Oku kukuvumela ukuba ukuthintela liphindwe ulahleko lwe data.

IO imposiso disk kwakhona zenzeka ngenxa kwindlela yefayile yonakele. Oku kwenzeka xa nesikhululo isuswe ngaphandle kokusebenzisa iifitsha zokhuseleko, kwakunye xa amandla elahlekile ngexesha udlulisela le data. Ngokomzekelo, cinga imeko ukuba umntu ukuthatha umfanekiso, kwaye ngeli xesha ibhetri iphele tu. Kulo mzekelo, kukho amathuba aphezulu yokusilela ikhadi lememori. Ukubuyisela inkqubo yefayile, zama ukuchwetheza kumgca command "chkdsk (unobumba drive): / r". Kubalulekile ukuba ubhale phantsi zonke iinkcukacha ukuba khompyutha uyakwazi ukufunda, phezu ukusebenza drive.

Enye impazamo igalelo-output kunokwenzeka ngenxa ukungasebenzi le umfundi ikhadi. Kulungile ukusebenzisa isixhobo yonke uyakwazi ukuxhasa izakhiwo ezininzi. Ukuphelisa unobangela yokusilela esi sixhobo ethile, khangela ukuba kukho naziphi na ngamaqhekeza kwaphulwa-off ngaphakathi intonga. Enye ukuba banikele ingqalelo ukuthembakala intambo.

Isizathu elandelayo kaninzi kubonakala imposiso IO kunokuba ukungavumelani kwe transfer ulwazi. Ekupheleni koo-, uninzi iikhompyutha inkxaso technology ufikelelo ebizwa DMA. Ukuba umatshini wakho uya kuzama ukuyisebenzisa ngenxa iinguqulelo ezindala drives flash oluxhasa kuphela imo ipha, impazamo-I output wangenwa yintaka. Njengoko sihlelwa xa yokusebenzisa yokugcina standard IiBhalbhu Flash. Oku akuvumelekanga ukuba ukudibanisa umfundi ikhadi ukuya umlawuli ATA kwi computer yakho.

Ukususa ezi iimpazamo, yiya kwi "Umphathi Device", apho kufuneka ufumane i candelo isilawuli, nto leyo impazamo imephu. Cofa i Izicwangciso Ezibhekisa phambili, skrolela ukwenza imo DMA kunye ayisuse elimakishayo. Oku kuya kuvumela umlawuli usebenze kwimo ipha. Apha, isimiso, kwaye zonke iimeko xa PC yakho okanye kwi laptop yakho bangakhupha mpazamo enjalo. Landela zonke iingcebiso, yaye yonke into iza kulunga.
