Inqubo ye-Init ingumama (umzali) wazo zonke izinqubo ohlelweni, wuhlelo lokuqala olusetshenziswa lapho uhlelo lwe-Linux luqala; ilawula zonke ezinye izinqubo ohlelweni. Iqalwa yi-kernel ngokwayo, ngakho-ke empeleni ayinayo inqubo yomzali. Inqubo ye-init ihlale ine-ID yenqubo engu-1.
Which process has a process ID of 1?
I-ID yenqubo 1 ivamise ukuba yinqubo ye-init ebophezelekile ngokuyinhloko ukuqala nokuvala isistimu. Ekuqaleni, inqubo ye-ID 1 ayizange ibekelwe i-init nganoma yiziphi izinyathelo zobuchwepheshe: imane inale ID njengomphumela wemvelo wokuba inqubo yokuqala ecelwe yi-kernel.

Which is the first process initialized by Linux kernel?
Imemori esetshenziswa uhlelo lwefayela lempande yesikhashana ibe isibuyiselwa. Ngakho, i-kernel iqalisa amadivayisi, ikhweza uhlelo lwefayela lwempande olucaciswe isilayishi sokuqalisa njengoba lufundwa kuphela, futhi lusebenzisa i-Init ( /sbin/init) eqokwe njengenqubo yokuqala eqhutshwa uhlelo (PID = 1).
Ingabe u-0 uyi-PID evumelekile?
Cishe ayinayo i-PID yezinjongo nezinjongo eziningi kodwa amathuluzi amaningi ayibheka njengo-0. I-PID ka-0 igcinelwe i-Idle “psuedo-process”, njenge-PID ye-4 ibekelwe Uhlelo (Windows Kernel ).
Ingabe i-ID yenqubo ihlukile?
I-id yenqubo/yochungechunge izohluka uma izinhlelo zisebenza ngesikhathi esisodwa njengoba i-OS idinga ukuzehlukanisa. Kodwa isistimu iphinda isebenzise ama-id.
Yini igama leNqubo?
