Answers
To create a non-updateable rental stats view that returns the rating column and a rent ratio column, we need to first access the film stats view of chapter 14 in the database. This view should contain the necessary data for us to calculate the rent ratio column.
1)Once we have accessed the film stats view, we can use SQL commands to create the rental stats view with the desired structure. The rental stats view should have two fields: the rating column, which should be of the enumerated type ('g', 'pg', 'pg-13', 'r', 'nc-17'), and the rent ratio column, which should be of decimal type with a precision of 24 and a scale of 4. Both fields should allow for null values.
2)To calculate the rent ratio column, we will divide the num rentals column by the inventory cnt column in the film stats view. This will give us the average number of rentals per inventory item for each rating. We will then use this value to populate the rent ratio column in the rental stats view.
3)Once we have created the rental stats view, we can run a query to display the desired data. The query should select all columns from the rental stats view where the rent ratio is greater than 4, and should order the results by rating. This query should display 130 rows of data, each containing a rating and rent ratio value for a particular movie rating.
4)Overall, creating a non-updateable rental stats view that returns the rating column and a rent ratio column is a straightforward process that involves accessing the film stats view, calculating the rent ratio column, and creating the rental stats view with the desired structure. Once the rental stats view is created, we can easily query it to display the desired data.

The voltage or current cycle's shape is described by the waveform. Bipolar current is a type of alternating current (AC) in which the flow of current alternates between positive and negative directions around zero.
Thus, An alternative is a direct current (DC), which has a single direction of flow (unipolarity), either positive or negative.
DC currents are frequently pulsed (pDC), which means that during a portion of the cycle duration, the current is stopped (at zero amplitude).
The mark space ratio (where the mark is the time the current is 'on' and the space is the time the current is 'off', i.e. at zero) can be used to describe the resulting waveform.

With the help of class and object we can implement the real world concept .The object is the run time entity of a class where as the class is physical entity .Without the object we can not implemented the object oriented programming.All the other option are not correct for the object because they are not described the identification of object .If you have verified that the update you made is correct, you can use the ____ command to make the update permanent.
a. ROLL
b. SAVE
c. COMMIT
d. UPDATE
Answers
The correct answer to the question is option C: COMMIT. Once you have made an update to a database, it is important to ensure that the changes you have made are saved permanently.
This is where the COMMIT command comes in handy. When you issue the COMMIT command, the changes that you have made are permanently saved to the database. This means that they will be available even if you close the database and reopen it at a later time. It is important to note that the COMMIT command is not the same as the SAVE command. The SAVE command is typically used to save a copy of a database or file to a different location, while the COMMIT command is used specifically to save updates to a database.
In conclusion, if you want to make sure that your database updates are saved permanently, you should use the COMMIT command. This will ensure that your changes are available for future use and will not be lost if the database is closed or shut down.

In Chapter 20 you read all about different types of private networks -- VLANs, NAT, PAT, and network segmentation. Additionally, the chapter covered virtual networks. Network virtualization has changed computing for the better. It saves money, allows for more scalability in networks, provides a more rich training environment since students or new hires are able to go out and "play" with the virtual machines and really get some hands-on experience! Some of you may not have really heard too much about virtual networks or how to use a virtual computer. For this discussion board, I want you to share with the class what experience (if any) you have with VMs. Initial Response Guidelines:
In roughly 100-150 words, describe to the class your experience with virtual networks or virtual computers. Virtual reality does not really count, but if it's all you have to discuss it will work. I want you to describe not only your experiences but also your thoughts on using virtual machines to save money, learn new techniques and any other aspects of VMs you want to share.
Answers
I have extensive experience with virtual networks and virtual machines (VMs). I have worked with various virtualization platforms like VMware, VirtualBox, and Hyper-V, both for personal use and in professional settings.
Virtual networks have been an integral part of my work and learning environment. They offer several advantages, including cost savings and increased scalability. By running multiple virtual machines on a single physical server, resources can be utilized more efficiently, reducing hardware costs. Moreover, VMs can be easily cloned, allowing for quick deployment and replication of complex network setups.
Using virtual machines has also enhanced my learning experience. I have been able to experiment with different operating systems, software configurations, and networking scenarios without the need for additional physical hardware. This hands-on approach has enabled me to gain practical skills, troubleshoot issues, and explore new techniques in a safe and isolated environment.
Overall, virtual machines have been invaluable tools for me. They have provided cost-effective solutions, facilitated learning opportunities, and allowed for the exploration of diverse network setups. The ability to create and manage virtual networks has not only saved money but also enriched my understanding of networking concepts and technologies.

Whilst it is impractical to convert all the numbers to binary, I will explain how binary works to you.
Binary is usually composed of eight bits, each representing a different number.
0000 0000
Each 0 represents a column in an 8-bit binary number. The far-right column starts at 1 and doubles each time you change to the left column.
128 64 32 16 8 4 2 1
0 0 0 0 0 0 0 0
A number 1 means that there is a number in that column whereas a 0 means there isn't, like the normal "0 means off and 1 means on" system. When there is a 1 in every column:
1 1 1 1 1 1 1 1
There can be a maximum value of 255.
For example, the number 79 would be represented in binary as:
128 64 32 16 8 4 2 1
0 1 0 0 1 1 1 1
64 + 8 + 4 + 2 + 1 = 79
