I-Hot-plugging, eyaziwa nangokuthi i-Hot Swap, isici esivumela abasebenzisi ukuthi basuse futhi bashintshe izingxenye zehadiwe ezilimele njengama-hard drive, izinsiza zamandla, noma amakhadi okunweba ngaphandle kokuvala isistimu noma ukunqamula amandla. Leli khono lithuthukisa ikhono lesistimu lokutholwa ngesikhathi kwenhlekelele, ukunwebeka, kanye nokuguquguquka. Isibonelo, izinhlelo ezithuthukisiwe ze-disk mirroring eziklanyelwe izinhlelo zokusebenza eziphezulu zivame ukunikeza ukusebenza kokuxhuma okushisayo.
Ngokwemibandela yezemfundo, ukuxhuma okushisayo kuhlanganisa Ukushintshwa Okushisayo, Ukunwetshwa Okushisayo, kanye Nokuthuthukisa Okushisayo. Yethulwe ekuqaleni esizindeni seseva ukuze kuthuthukiswe ukusebenziseka kweseva. Kumakhompyutha ethu ansuku zonke, ukuxhumana kwe-USB kuyizibonelo ezivamile zokuxhuma okushisayo. Ngaphandle kokuxhuma okushisayo, noma ngabe idiski ilimele futhi ukulahleka kwedatha kuvinjiwe, abasebenzisi basadinga ukuvala okwesikhashana isistimu ukuze babuyisele idiski. Ngokuphambene, ngobuchwepheshe bokuxhuma okushisayo, abasebenzisi bangavele bavule inkinobho yokuxhuma noma isibambo ukuze bakhiphe idiski ngenkathi uhlelo luqhubeka nokusebenza ngaphandle kokuphazamiseka.
Ukusebenzisa i-hot-plugging kudinga ukusekelwa ezicini ezimbalwa, okuhlanganisa izici zikagesi webhasi, i-BIOS yebhodi lomama, isistimu yokusebenza, nezishayeli zedivayisi. Ukuqinisekisa ukuthi indawo ezungezile ihlangabezana nezidingo ezithile kuvumela ukufezeka kokuxhuma okushisayo. Amabhasi esistimu yamanje asekela kancane ubuchwepheshe bokuxhuma okushisayo, ikakhulukazi kusukela enkathini ye-586 lapho ukunwetshwa kwamabhasi angaphandle kwethulwa. Kusukela ngo-1997, izinguqulo ezintsha ze-BIOS zaqala ukusekela amakhono e-plug-and-play, nakuba lokhu kusekelwa bekungahlanganisi ukuxhuma okugcwele okushisayo kodwa kuhlanganisa kuphela okushisayo nokushintshwa okushisayo. Kodwa-ke, lobu buchwepheshe buvame ukusetshenziswa kakhulu ezimeni zokuxhuma okushisayo, ngaleyo ndlela kunqobe ukukhathazeka kwe-BIOS yebhodi lomama.
Mayelana nesistimu yokusebenza, ukusekelwa kwe-plug-and-play kwethulwa nge-Windows 95. Nokho, ukusekelwa kokuxhuma okushisayo bekunomkhawulo kuze kube yi-Windows NT 4.0. I-Microsoft ibone ukubaluleka kokuxhuma okushisayo esizindeni seseva futhi ngenxa yalokho, ukwesekwa okugcwele kwe-hot-plugging kwengezwa ohlelweni lokusebenza. Lesi sici saqhubeka ngezinguqulo ezalandela ze-Windows ezisekelwe kubuchwepheshe be-NT, okuhlanganisa i-Windows 2000/XP. Inqobo nje uma kusetshenziswa inguqulo yesistimu yokusebenza engaphezulu kwe-NT 4.0, usekelo olubanzi lwe-hot-plugging luyahlinzekwa. Ngokwabashayeli, ukusebenza kwe-hot-plugging kuhlanganiswe kubashayeli be-Windows NT, i-Novell's NetWare, ne-SCO UNIX. Ngokukhetha abashayeli abahambisana nalawa masistimu okusebenza, into yokugcina yokuzuza amandla okuxhuma okushisayo iyagcwaliseka.
Kumakhompyutha ajwayelekile, amadivaysi axhunywe nge-USB (Universal Serial Bus) interface kanye ne-IEEE 1394 interface angafinyelela ukuxhuma okushisayo. Kumaseva, izakhi ezingase zixhumeke ngokushisayo zifaka phakathi ama-hard drive, ama-CPU, inkumbulo, izinsiza zamandla, abalandeli, ama-adaptha e-PCI, namakhadi enethiwekhi. Lapho uthenga amaseva, kubalulekile ukunaka ukuthi yiziphi izingxenye ezisekela ukuxhuma okushisayo, njengoba lokhu kuzoba nomthelela omkhulu ekusebenzeni kwesikhathi esizayo.
