Question
Chapter 12, Problem 1RQ
Program Plan Intro
Waterfall model:
- Waterfall model is the first process model in which each phase is completed before starting the next phase.
- It is the first Software Development Life Cycle (SDLC) approach used for developing the software.
- It includes six different types of phases and they are as follows
- Investigation
- The clear understanding of the problems in a system and solving them is performed in investigation phase.
- This helps in developing the project in less time.
- Analysis
- Gathering the data from the existing system and determining the requirements for new systems is done in analysis phase.
- It defines the user requirements and expectations.
- Design
- The existing program or code is executed according to the required design.
- It mainly depends on user requirements.
- Its aim is to convert the user requirements to a complete system.
- Construction
- Construction phase is used to execute the code according to design.
- It is managed by the group of programmers or developers called development team.
- Integration and Testing
- In integration and testing phase, the individual programs or codes are integrated together and tested as group.
- It is used for finding the errors and solving them.
- Implementation
- It is the last phase of the project development process in which development of the project is implemented and maintained.
- It includes user preparation, site preparation, installation and many such.

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.
