The use of the inheritance to have a structure inherit attributes and methods of classes above it.
One of the key milestones in the period in which the object-relational model was created was the creation of a data
model that closely represented the real world. In this approach, objects were created in which both data and its
relationships were all contained in one place. These data models were becoming a norm to be stored on the web. They
also incorporated support for star schemas within data warehouses. Objects that had similar characteristics were
grouped into classes, where they had a shared structure of attributes and behaviors.
Answer:
a.the number of cycles per second
Explanation:
The frequency of a sine wave is defined as the number of cycles per second.
Frequency is the inverse of the time period. The frequency of a sine wave is given by 1/TimePeriod . It is generally expressed in units of Hertz(Hz) or sec^-1. Larger the time period, lower will be the frequency and vice versa. So for higher frequency waves we need to ensure that the time period is small.
Answer:
Virtualization is the technology that is used to create virtual representation and version of the different devices like software, many storage devices and server.
It also help in organize the working framework where the structure isolates the asset into at least one execution situations.
The benefits of using the virtualization on the single machine are:
- The virtualization increased the productivity when it used in the cluster environment.
- We can able to access the different resources faster.
- The data center management is simple while using the virtualization in the cluster environment.
The drawback of using virtualization on single machine are:
- The virtual machine is less efficient as compared to the real machines.
- The virtual machine indirectly access the computer hardware system so that is why it is less efficient and also consume more power to run the system.
If only S1 is closed, due to the diode across S3 is pointing to the right, the current cannot be flowing to the left.
So nothing will happen, the bulb is not on.
