Slide3Variable Lock(1) Variable Lock(1) Kelemahan/Kesalahan : 2 buah proses dapat memasuki critical section pada saat yang bersamaan Hal ini disebut dengan Race Condition
Slide4Simulasi Variable Lock Simulasi Variable Lock PLAY
Slide5Lock = 1Lock = 0 P2 P2 P3 P3 Cek OK ! Masuk Critical Section CRITICAL SECTION P1 P1
Slide6Lock = 0Lock = 1 Lock = 0 P3 P3 CRITICAL SECTION P1 P1 wait OK ! Masuk Critical Section P2 P2
Slide7Pemberian Variable Lock adalah agar dalam 1 waktu , hanya ada 1 proses pada Critical Section
