System development: It is a collection of activities that is used in order to create an information system . The activities that are done during system development are called as phases and the set of phases is known as system development life cycle. There are five phases in system development process. They are: Planning – In this phase, all the requirements and information are gathered from the customer. Analysis – This phase is used to break down the deliverables into detailed business requirements. Design – In this step, the requirements gathered are used to develop the application or a product. Implementation – Here, all the components of the application is implemented in this phase. Support and security – This phase is to offer ongoing assistance for the information system.

System development:

It is a collection of activities that is used in order to create an information system.

The activities that are done during system development are called as phases and the set of phases is known as system development life cycle.

There are five phases in system development process. They are:

Planning – In this phase, all the requirements and information are gathered from the customer.

Analysis – This phase is used to break down the deliverables into detailed business requirements.

Design – In this step, the requirements gathered are used to develop the application or a product.

Implementation – Here, all the components of the application is implemented in this phase.

Support and security – This phase is to offer ongoing assistance for the information system.

6.3A-3. Multiple Access protocols (3). 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 2

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?
