Answer:
Digital electronics involves 2 states which are abstracted as 0/1 or true/false.
Explanation:
Digital electronics involves 2 states. For TTL logic this corresponds to 0 Volt (0) or 5 Volt (1). Analyzing further, a digital waveform has a square shape (not necessarily a perfect square) with 2 levels denoting the two states, namely, true(1) or false(0). So a 0 or 1 is not actually absolute but 0 corresponds to voltage level below a threshold voltage whereas 1 corresponds to voltage level above a threshold voltage.
First question: On the Format tab, in the Arrange group, click Wrap Text. Do one of the following: Click Square to wrap text around the border of your image. Click Tight to wrap text closely around an irregularly shaped picture.
Second question: you use text wrapping when you want to surround a picture or diagram with text.
Hope this helps!
Answer:
1.) Relative cell reference - A1
2.) Absolute cell reference - $D$2
3.) Mixed cel reference - $D2
Explanation:
In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.
A cell reference is a cell address or a range of cell addresses that can be used in a formula.
There are three types of cell references and they are;
a) Relative reference
b) Absolute reference
c) Mixed reference
A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.
An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.
Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.
