Expert Solution & Answer
Chapter 4, Problem 3WE
Explanation of Solution
Real-time
- It is a multiprogramming system that aims at executing real time applications.
- This operating system immediately responds to the given input. The task in this system is completed within a specified period of time.
- This OS is a time-sharing system which is based on clock interrupts.
- This operating system execute the process by using priority.
- Once a high priority process arrives into the system, low priority process preempted to support the high priority process.
- There are two types in the real-time operating system:
- Soft real-time operating system:
- In this operating system, a process might not be performed in given limit. This type is able to cross the limit without damaging the given machine.
- Example for this type is multimedia transmission and reception.
- Hard real-time operating system:
- In this operating system, a process should be executes in given limit...
- Soft real-time operating system:
Explanation of Solution
Difference between real-time and non-real-time operating system:
The difference between the real-time and non-real-time operating system is given below:
| Real-time operating system | Non-real-time operating system |
| This operating system is deterministic. | This operating system is not deterministic. |
| It is time sensitive. | It is time insensitive. |
| It can’t use virtual memory. | It can use concept of virtual memory. |
| It is mostly used in the embedded application. | It is mostly used in the desktop and personal computer... |
Explanation of Solution

Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2, 3.3, 4.1. Each transmission requires exactly one time unit. 1 t=0.0 2 3 45 t=1.0 t-2.0 t-3.0 6 t=4.0 t-5.0 For the CSMA protocol (without collision detection), indicate which packets are successfully transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy, then that node will not attempt a retransmission of that packet until sometime after t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.] ☐ U ப 5 - 3 1 4 6 2arrow_forward
- Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still? Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?arrow_forwardHow to develop a C program that receives the message sent by the provided program and displays the name and email included in the message on the screen?Here is the code of the program that sends the message for reference: typedef struct { long tipo; struct { char nome[50]; char email[40]; } dados;} MsgStruct; int main() { int msg_id, status; msg_id = msgget(1000, 0600 | IPC_CREAT); exit_on_error(msg_id, "Creation/Connection"); MsgStruct msg; msg.tipo = 5; strcpy(msg.dados.nome, "Pedro Silva"); strcpy(msg.dados.email, "pedro@sapo.pt"); status = msgsnd(msg_id, &msg, sizeof(msg.dados), 0); exit_on_error(status, "Send"); printf("Message sent!\n");}arrow_forward9.
