Answer:
Hi, for this exercise we have two laws to bear in mind:
Morgan's laws
NOT(А).NOT(В) = NOT(A) + NOT (B)
NOT(A) + NOT (B) = NOT(А).NOT(В)
And the table of the Nand
INPUT OUTPUT
A B A NAND B
0 0 1
0 1 1
1 0 1
1 1 0
Let's start!
a.
Input OUTPUT
A A A NAND A
1 1 0
0 0 1
b.
Input OUTPUT
A B (A NAND B ) NAND (A NAND B )
0 0 0
0 1 0
1 0 0
1 1 1
C.
Input OUTPUT
A B (A NAND A ) NAND (B NAND B )
0 0 0
0 1 1
1 0 1
1 1 1
Explanation:
In the first one, we only need one input in this case A and comparing with the truth table we have the not gate
In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.
In the third case we have that the OR is A + B and we know in base of the morgan's law that:
A + B = NOT(NOT(А).NOT(В))
So, we have to negate the two inputs and after make nand with the two inputs negated.
I hope it's help you.

¿???????????? SORRY..........
Answer:
All of the above.
Explanation:
In Computer science, a bit is a short word for the term binary digit and it's primarily the basic (smallest) unit measurement of data or information.
A bit is a logical state which represents a single binary value of either one (1) or zero (0). This ultimately implies that, a single bit in computer science represents a boolean value of;
- True or ON, which is equal to one (1).
- False or OFF, which is equal to zero (0).
Therefore, a bit that is turned off represents the value of binary numbering because it has a numerical value of zero (0).
A binary sequence represents all binary digits that are to be written in sequences of ones (1s) and zeroes (0s). Hence, a binary sequence can be used to encode data such as sound (audio) strings of characters, video, images, colors, computer instruction codes etc.
<em>The true statements about the data that can be represented using binary sequences are;</em>
1. Binary sequences can be used to represent strings of characters.
2. Binary sequences can be used to represent colors.
3. Binary sequences can be used to represent audio recordings.
Answer:
Spreadsheet.
Explanation:
Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.
The document that is use in excel to store a work with data that's formatted in a pattern of uniformly spaced horizontalal and vertical lines is called a spreadsheet.
A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.
Additionally, workbooks are known as Microsoft Excel files. An Excel workbook can be defined as a collection of one or more charts and worksheets (spreadsheets) used for data entry and storage in an excel file. In order to create a project on Excel you will have to use a workbook.
