Answer:
While loops are typically used when you don’t know how many times the loop needs to repeat. The body of the loop will repeat while the condition is true. The logical expression will be evaluated just before the body of the loop is repeated.
Let’s say that we want to find the square root of a number. For some square roots, you’re never going to be exact. Let’s say that we want to find a square root that, when multiplied by itself, is within 0.01 of the square we want. How do we do it? There’s a really old process that we can apply here.
Start by guessing 2.
Compute the guess squared.
Is the guess squared close to the target number? If it’s within 0.01, we’re done. We’ll take the absolute value of the difference, in case we overshoot. (In Python, abs is the absolute value function.)
If it’s not close enough, we divide the target number by our guess, then average that value with our guess.
That’s our new guess. Square it, and go back to Step #3.

Answer: Database design is the model created of data/information for any particular organization .the relation between the information and which data is to be stored is the most important factor for designing .These parameters are decided by the designer of the database.
After the decision of the designed the data is invoked in the database .The data representation in the theoretical manner is known as ontology.The classification and relation defining is the purpose of the database design.
Answer:
Correct Order
2. Select the cell or range you want to move or copy.
1. Move the pointer over the border of the selection until the pointer changes shape.
3. To move the range, click the border and drag the selection to a new location, or to copy the range, hold down the Ctrl key and drag the selection to a new location.
Explanation:
To move or copy range of cells in MS Excel, You first select the cell/range you want to move or copy, hover the mouse pointer and take note when it changes shape, then finally click the border (when you noticed the change of shape of the pointer) and hold down the ctrl key and drag it to the destination location.
