Every school is different. Some you have to keep above a C average. Others you only have to be passing. You will have to check your student handbook.
Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
Answer:
No.
Explanation:
Because wives should make decisions for their life themselves.It helps them be self dependent so that they won't have to depend on their husbands. By letting them make decisions themselves they can get a successful career on their own effort and decisions.
The correct answer is letter c. exhaust manifolds. Most V-type engines use two exhaust manifolds, one attached to each cylinder head. An exhaust manifold in automative engineering refers to the collection of the exhaust gases from different cylinders into another single pipe.
Waiting time for a 100 Mbps broadcast channel is 0.512 ms
Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,
where K is drawn randomly. For K = 100,
The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms
The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms
Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms
Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms
<h3>
What is a collision in Ethernet?</h3>
- A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time.
- The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them.
- On Ethernets, collisions are unavoidable.
- A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work.
- Collisions entail the application of force (there is a change in velocity).
