The most common operating system for personal computers is Windows.
The OSI model layer that provides a user interface in the form of an entry point for software programs to access the network infrastructure is: application layer.
<h3>What is the
OSI model?</h3>
OSI model is an acronym for open systems interconnection and it comprises seven (7) main layers, which typically starts from the hardware layers (layers in hardware systems) to the software layers (layers in software systems)
<h3>The layers of the
OSI model</h3>
In Computer networking, the seven (7) layers of the OSI model include the following in sequential order;
The uppermost layer of the OSI model which is the "application layer" gives software programs an access to the services that allow internet connection or network infrastructure.

Answer:
C. 14.4 kwhr.
Explanation:
To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is 
, where V stands for voltage and I stands for current.
In the given problem, V = 240 volts and I = 15 amp. Therefore,
Now, formulae for calculating energy used i.e. work(W) is 
, where <em>t</em> is the time.
In the given question time is 4 hr. Therefore energy used will be,
Energy used (W) = 
.
Answer:
Yes, Its a good idea but depends upon type of image. Like adding a logo to all the slides at top left corner is not just good but a must for all as well, when we are preparing official documents. However, other images when decided to be repeated must convey the correct intent in each page. If this is not the case, you need to avoid it. Intent is the most important aspect certainly. For rest see explanation.
Explanation:
Yes, and as mentioned above adding logo and other images meaningfully, and with correct intent is a good idea.
However, images must not be blurred, tiny or stretched. Also proper cropping is a must. The border should be solid as well. And when selecting a lot of images, the images must convey the correct meaning together. Moreover, the aspect ratio after stretching must be same as the original. You can do this in PowerPoint by going to format > crop > fill.
Ensure that watermarks are not revealed. Buy them rather than copy from somewhere for better outcome. And never amputate your readers with a headache creating backgrounds. You will loose readers then. The clip arts must be used in right number, and not a lot of them certainly.
Ensure both text and images are in correct ratios. Avoid using more than 2 images per slide.
