Resumen del Recurso

Pregunta 1

Pregunta
A program
Respuesta
  • 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

Pregunta 13

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

Pregunta 14

Pregunta
With the use of swapping one other state must be added to the 5-state model:
Respuesta
  • Suspend state
  • Resume state
  • Blocked state

Pregunta 15

Pregunta
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:
Respuesta
  • state
  • listing
  • fetch
  • trace

Pregunta 16

Pregunta
The state of a process is defined by:
Respuesta
  • 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

Pregunta 17

Pregunta
In the Blocked state:
Respuesta
  • 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

Pregunta 18

Pregunta
In the Ready/Suspend state:
Respuesta
  • 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

Pregunta 19

Pregunta
In the Exit state:
Respuesta
  • 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

Pregunta 20

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

Pregunta 21

Pregunta
Identify which state the process will transit: P2 is chosen by dispatcher
Respuesta
  • Exit
  • Blocked/Suspend
  • Running
  • Ready
  • Blocked
  • New
  • Ready/Suspend

Pregunta 22

Pregunta
The data neede by the OS to control a process is contained in the:
Respuesta

Pregunta 25

Pregunta
A reason for swapping:
