Lecture 1

Process

• Virtual Address

• Process Image

• Process model’s limitation is cooperating & multiprocess (sharing is limited)

• So we use
  Thread

Process Control Block

• Process switching
• Process switching case
• Process switching steps
• thread_struct,
  Hardware Context

Thread

• Multi-threading
• clone()
• fork()
• vfork()
• do_fork()
• System call
• Linux Kernel function

• Kernel thread
• Linux Init Process

Lecture 2

Process Scheduling

• Preemption

• Job scheduler
• Time quantum
• Process Priority

• Queueing theory
• FIFO Algorithm
• Round Robin

• Schedule Invocation

• Process Priority

Linux Scheduler

• O(n) scheduler

• O(1) scheduler
