Question 1

Question
A program
Answer
  • is a device where information is stored.
  • is a device that performs a sequence of operations specified by instructions in memory.
  • is a sequence of instructions

Question
In the Running state:
Answer

Question 13

Question
Suppose that the process is in “Blocked” state waiting for some I/O device. When the service is completed, it goes to the
Answer
  • Terminated state
  • Ready state

  • Running state

Question 14

Question

Question 15

Question
We can characterize the behavior of an individual process by listing the sequence of instructions that execute for that process. Such a listing is referred to as:
Answer
  • state
  • listing
  • fetch
  • trace

Question 16

Question
The state of a process is defined by:
Answer
  • The activity to next be executed by the process
  • The current activity of the process
  • The activity just executed by the process
  • The final activity of the products

Question 17

Question
In the Blocked state:
Answer
  • The process cannot execute until some event occurs
  • The process is available for execution as soons as it is loaded into main memory
  • The process has been created but has not yet been admitted to the pool of executable processes
  • The process has been released from the pool of executable processes
  • The process is currently being executed
  • The process is prepared to execute

Question 18

Question
In the Ready/Suspend state:
Answer
  • the process is available for execution as soon as it is loaded into memory
  • the process is currently being executed
  • the process cannot execute until some event occurs
  • the process has been created but has not yet been admitted to the pool of executable processes
  • the process has been released from the pool of executable processes
  • the process is prepared to execute

Question 19

Question
In the Exit state:
Answer
  • the process cannot execute until some event occurs
  • the process is currently being executed
  • the process is available for execution as soon as it is loaded into memory
  • the process is prepared to execute
  • the process has been released from the pool of executable processes
  • the process has been created but has not yet admitted to the pool of executable processes

Question 20

Question
Identify which state the process will transit: P3 swapped out
Answer
  • Ready
  • New
  • Running
  • Blocked/Suspend
  • Blocked

Question 22

Question
The data neede by the OS to control a process is contained in the:
Answer

Question 25

Question
A reason for swapping:
Answer
  • processor is so much faster than I/O, it will be common for all processes in memory to be waiting for I/O
