The statement "Flowcharts cannot be used to describe business relationships between participants in a management system" is not true about flow chart.
Flowcharts can indeed be used to describe business relationships between participants in a management system. However, they are primarily used to visually describe a working process in a step-by-step manner, and any complete flow chart must have a unique start box and a unique end box. Additionally, the flow chart must be clear to be effective.

8. Answer the following a) Draw the flowchart and hardware implementation of division. b) Solve the below problem using multiplication algorithm Multiplicand=0010, Multiplier=0011
a) Flowchart and hardware implementation of division:
Flowchart:
```
Start
Input dividend (D) and divisor (d)
Set quotient (Q) = 0
Set remainder (R) = 0
While D >= d do
Subtract d from D
Increment Q
End While
Set R = D
Output Q and R
End
```
Hardware implementation:
The hardware implementation of division involves a series of subtractions and comparisons to determine the quotient and remainder. Here is a basic diagram of the hardware implementation:
```
_________________
| |
Dividend --| Subtractor |
|_________________|
|
| _______________
| | |
|------->| Comparator |
| |_______________|
|
| _____
| | |
| | 0 |
| |_____| Quotient
|
| _____
| | |
| | 0 |
| |_____| Remainder
|
V
Output registers
```
b) Multiplication algorithm:
To multiply the multiplicand (0010) by the multiplier (0011), we can use the following algorithm:
1. Set the result to 0.
2. For each bit in the multiplier, starting with the least significant bit:
a. If the bit is 1, add the multiplicand to the result.
b. Shift the multiplicand left by 1 bit.
3. The final result is the product of the multiplicand and multiplier.
Using this algorithm, we can perform the multiplication as follows:
```
0010 (multiplicand)
x 0011 (multiplier)
-------
0010 (add 0, since last bit of multiplier is 0)
+00100 (add 0010, since second-to-last bit of multiplier is 1)
-------
0110 (product)
```
Therefore, the product of the multiplicand (0010) and the multiplier (0011) is 0110.
draw a labelled schmatic diagram of 4-bit Shift Register
Sure, here is a labelled schematic diagram of a 4-bit shift register:
```

CP \ \ | |
\ \ | |
\__\| D |--- Q1

```
In this diagram, "CP" represents the clock pulse input, "D" represents the data input, and "Q0" through "Q3" represent the four output bits. The clock pulse input controls when the data is shifted through the register, and the data input determines what data is shifted in. Each output bit represents a stage in the shift register, with the output of each stage being fed into the input of the next stage.
