STRUKTUR SISTEM OPERASI

1. STRUKTUR SISTEM OPERASI

Secara umum, Sistem Operasi adalah software pada lapisan pertama yang ditempatkan pada memori komputer pada saat komputer dinyalakan. Sedangkan software-software lainnya dijalankan setelah Sistem Operasi berjalan, dan Sistem Operasi akan melakukan layanan inti umum untuk software-software itu. Layanan inti umum tersebut seperti akses ke disk, manajemen memori, skeduling task, dan antar-muka user. Sehingga masing-masing software tidak perlu lagi melakukan tugas-tugas inti umum tersebut, karena dapat dilayani dan dilakukan oleh Sistem Operasi. Bagian kode yang melakukan tugas-tugas inti dan umum tersebut dinamakan dengan “kernel” suatu Sistem Operasi. Kalau sistem komputer terbagi dalam lapisan-lapisan, maka Sistem Operasi adalah  penghubung antara lapisan hardware dan lapisan software. Lebih jauh daripada itu, Sistem Operasi melakukan semua tugas-tugas penting dalam komputer, dan menjamin aplikasi-aplikasi yang berbeda dapat berjalan secara bersamaan dengan lancar. Sistem Operasi menjamin aplikasi software lainnya dapat menggunakan memori, melakukan input dan output terhadap peralatan lain dan memiliki akses kepada sistem file. Apabila beberapa aplikasi berjalan secara bersamaan, maka Sistem Operasi mengatur skedule yang tepat, sehingga sedapat mungkin semua proses yang berjalan mendapatkan waktu yang cukup untuk menggunakan prosesor (CPU) serta tidak saling mengganggu.

Berikut ini adalah Struktur Sistem Operasi;

• Struktur Sederhana ( system Monoiltik )

• Sistem Berlapis  ( layered system )

• Kernel Mikro

• Modular ( Modules )

• Mesin Maya (  Virtual Machine )

• Client-Server Model

• Sistem Berorientasi Objek baca selengkapnya
