   		First Come First Serve
   		Shortest Job First
   		Shortest Remaining Job First
   		Priority Scheduling

2. Which of the following is NOT the property of a critical section?

   		Mutual Exclusion: If one process is in the critical section then no other process can be in its critical section at the same time
   		Progress: Process should be progressing in the Critical Section
   		Preemption: Process should be preempted in the critical section
   		Fairness: A bound wait must exist on the number of times process are allowed to enter the critical section

   		Ready

1. Which of the following is NOT the goal of an Operating System?

   		Convenient to use the computer system
   		Meet individual user needs
   		Make Problem Solving easier
   		Efficient use of hardware

1. Short process scheduled behind the long process leads to:

   		Busy waiting
   		Deadlock
   		Starvation
   		Convey effect

Answer 1

• Convey effect is related to the first-come-first-serve(FCFS) algorithm in which whole os slows down due to slow processes.
• Preemption is not a property of critical section.
• Spooling acts as a buffer to store the data of the device until it is ready to accept the job.
• There are 3 components in a computer system-input unit,output unit,cu.
• Process control block
• Asynchronous transmission has start and stop bits.
• Linux is structured using loadable module structure.
• CPU sees logical view of the memory.
• Goal of the os is not to meet individual's need.
• It can lead to starvation.
