Kwi-computing, umbhobho ogama lingu (ekwaziwa ngokuba yi-FIFO ngokuziphatha kwayo) kukwandiswa kwengcamango yombhobho wendabuko kwiinkqubo ezifana ne-Unix kunye ne-Unix, kwaye yenye yeendlela zonxibelelwano phakathi kwenkqubo (IPC). Ingqikelelo ikwafumaneka kwi-OS/2 nakwi-Microsoft Windows, nangona i-semantics yahluka kakhulu.
Yintoni ebizwa ngokuba yimibhobho kwiLinux?
I-FIFO, eyaziwa ngokuba ngumbhobho ogama lingu ifayile ekhethekileyo efana nombhobho kodwa enegama kwindlela yefayile.

Inokususwa xa ingasasetyenziswa. Ngokuqhelekileyo umbhobho onikwe igama uvela njengefayile kwaye iinkqubo ngokubanzi zincamathele kuyo kunxibelelwano lwenkqubo phakathi.
Isetyenziselwa ntoni imibhobho?

- $ echo "molo" >> pipe1. Ngoku kwifestile yokuqala unokubona "molo" eprintiweyo:
- $ umsila -f pipe1 molo. Kuba ngumbhobho kwaye umyalezo udliwe, ukuba sijonga ubungakanani befayile, unokuyibona isengu-0:

Yintoni umahluko phakathi kombhobho kunye ne-FIFO?
Umbhobho yindlela yonxibelelwano lwenkqubo; idatha ebhaliweyo kumbhobho ngenkqubo enye inokufundwa ngenye inkqubo. … A Ifayile ekhethekileyo yeFIFO ifana nombhobho, kodwa endaweni yokungaziwa, uqhagamshelwano lwexeshana, iFIFO inegama okanye amagama njengayo nayiphi na enye ifayile.
