Chapter 1, Problem R19RQ

Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2 = 2 Mbps, and R3 = 1 Mbps.

  1. a. Assuming no other traffic in the network, what is the throughput for the file transfer?
  2. b. Suppose the file is 4 million bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B?
  3. c. Repeat (a) and (b), but now with R2 reduced to 100 kbps.

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?
How 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");}
