State Proses pada Sistem Operasi

Proses pada system operasi dapat diartikan sebuah atau ebberapa program yang dijalankan atau di eksekusi dimana program tersebut berupa perintah – perintah yang membutuhkan beberapa sumber daya tertentu.

Ada tiga macam state dasar dalam proses yaitu ready, running dan blocked. Pada awalnya proses berada pada state ready dimana proses siap untuk di eksekusi atau dijalankan. Kemudian memasuki state berikutnya yaitu state running. State running menandakan bahwa proses saat ini sedang berjalan atau sedang dieksekusi oleh prosesor. Yang trakhir state blocked ini maksudnya adalah adanya proses yang menunggu suatu perintah berikutnya. Sebuah proses dapat meninggalkan state running meskipun dalam keadaan state ready atau blocked jika terjadi kesalan atau sengaja digagalkan atau dihentikan oleh user.
