Answer:
This Print Screen key is used to take the screenshots of all that is appearing on the screen, and this can then be pasted in paint and saved in some location of the computer.
The Home key takes the cursor from the current position to the top left, or the start of the file.
Shift: There are two shift keys. And they are used to print the character in the capital. And when the caps lock is busy it can be used to print in lower case. It is also used together with arrow keys to select a part of the text.
Tab: This key moves the cursor from the current location to the location which we know as tab stops ( and the very next one).
Pg Up: The page up is being used for scrolling up, and the distance to which limit the scrolling will take place depends upon the application you are working on.

Answer:
There are certainly many hidden costs, and you need to find them out. I am listing some. The GPU can cost a lot if you are using them for complex computing like in the case of Bitcoin. You need to pay heavy electricity bills as well. And if you want to install the webserver then as well, you need to keep your computer open all the time, and pay a good sum as an electricity bill. Many more hidden costs can be found. And one out of above is used in Schools, the webserver. Some more hidden costs can be Network cost, as the school is big, and you need to connect all through LAN, and at times we also need WAN set up. And these are another hidden cost. Various education licenses come for free, and smart classes cost as well. The video conferencing, VOIP, etc costs as well. Smart classes training by various computer training institute for teachers like one from adhesive.

Answer:
There's a parking lot that is 600m² big. The lot must be able to hold at least 3 buses and 10 cars.
Each car takes up 6m² and each bus takes up 30m².
However, there can only be 60 vehicles in the lot at any given time.
The cost to park in the lot is $2.50 per day for cars and $7.50 per day for buses. The lot must make at least $75 each day to break even.
What is a possible car to bus ratio that would allow the lot to make profit?
Answer:
The correct answer is A.
Explanation:
Moore's Law states/predicts that the maximum number of transistors that can be used on integrated circuits (processors etc.) will be doubled every two years so it basically predicts an exponential growth in terms of transistors used.
Doubling the number of transistors used means that it will almost certainly increase the performance of the processors. Of course there are a lot of other variables that the performance depends on but Moore's Law is proven to be true and is being used since 1960's. The answer given in option A is the one that best reflects on this law.
I hope this answer helps.
